Best Ariens Genuine OEM Ariens 5 16th Deluxe
As an Amazon Associate we earn from qualifying purchases.
If you searched for the best Ariens genuine OEM Ariens 5 16th Deluxe part, this page covers one product: a three-pack of genuine Ariens shear bolts with nuts, model 52100100. A shear bolt is a deliberately weak link between the auger and the auger shaft, and it breaks when the auger meets a solid object. The listing says the set does not work with pre-2008 Deluxe or Pro units, and it states no other fit limits. The listing was read on 2026-10-23. The Ariens support article was opened the same day, and the Illinois Extension page is reused from another post with its original opened date of 2026-10-22.
Quick answer
- The listing describes a three-pack of genuine Ariens 5/16-inch Deluxe Platinum Pro snow thrower shear bolts and nuts, model 52100100.
- The listing says the set does not work with pre-2008 Deluxe or Pro units. Check your model year and the part number in your owner’s manual before you order.
- Ariens says a shear pin breaks by design to protect the auger gearcase, and it recommends keeping spares on hand.
- Buy it if your Ariens snow thrower is a 2008 or newer Deluxe or Platinum Pro that takes this part number. Look again if the manual lists a different pin or size.
The product at a glance
The table lists what the Amazon listing states. Where the listing is silent, the cell says “not stated”.

| Model number | 52100100 |
| Manufacturer part number | 521001×3 |
| Description | 5/16-inch Deluxe Platinum Pro snow thrower shear bolts and nuts |
| Pack count | 3 (number of items 3) |
| Genuine status | Genuine Ariens part, described as genuine OEM |
| Fit limit | Does not work with pre-2008 models of Deluxe or Pro units |
| Item weight | 1.6 ounces |
| Color | Gray |
| Bolt length | Not stated |

The listing uses the same part number in the title, the model number and the description. That consistency helps, because a buyer can check one number against the owner’s manual and the box.
The arithmetic here is small but useful. Three pins at 1.6 ounces in total is the listing’s own weight figure, so each pin is roughly half an ounce if the pack is evenly weighted. The listing does not give a weight per pin, so treat that as a rough division, not a stated spec. What matters more is the count: Ariens says every two-stage snow blower has at least one shear pin on each side of the auger gear case, which means a machine with two pins needs two of the set, and a machine with more needs more.
Who it suits
It suits an owner of a 2008 or newer Ariens Deluxe or Platinum Pro snow thrower who needs a replacement shear bolt. The listing gives that model-year limit, and its title and description name the Deluxe and Platinum Pro models. The part is described as a genuine Ariens part, so an owner who wants a factory match rather than an aftermarket pin has a clear reason to choose it.
It suits an owner who wants a spare on hand. Ariens says, “We recommend keeping extra shear pins on hand because you never know when you’ll need them.” A three-pack gives you a replacement for the pin that breaks and a spare for the next jam, which is the use the manufacturer describes.
It suits someone replacing pins in a two-stage machine. Ariens says, “All two-stage snow blowers have at least one shear pin on each side of the auger gear case.” A reader who knows the pin position and size from the manual can match the set to the job without guessing.
It suits a reader who needs to confirm a break before buying. Ariens describes the symptom: “If it feels like your snow blower is pushing snow rather than processing it, or if you see snow building up outside either side of your auger housing, you likely broke a shear bolt.” If that matches what you see, the part is the repair, and the model check comes next.
It also suits someone who wants to avoid the wrong pin size. The Ariens article warns that a pin able to take more torque than the machine can cause extensive damage, so a genuine part with a checked number removes one guess from the job.
Skip it if
Skip it if your snow thrower is a pre-2008 Deluxe or Pro. The listing says the set does not work with those units, so a fit mismatch would be a return, not a repair.
Skip it if your owner’s manual gives a different part number or pin size. Ariens says, “Make sure to use the right size shear pin for your snow blower.” It also says, “Reference the service parts section of your owner’s manual to identify the correct part number for your unit.” Do that check before you order, not after.
Skip it if you cannot confirm the match. Ariens warns that a pin rated for more torque than the machine can cause damage. In its words, “If you use a pin that can handle more torque than your machine, you risk causing extensive damage to your snow blower.” A part number you have checked is safer than a part that looks the same.
Skip it if you need a bolt length, a material grade or a warranty term before you buy. None of those is stated in the text read, and the listing’s warranty link was not opened for this post.
What the listing does not say
The fit limit is the first gap. The listing says “Does not work with Pre-2008 models of Deluxe or Pro units”, but it does not list the models or serial ranges that do fit. A buyer with a 2008-or-newer machine still has to check the part number in the owner’s manual, because the listing does not confirm it against a model list.
The dimensions are the second gap. The listing gives a 5/16-inch size in the description, but it does not state bolt length, thread pitch, material or hardness. Ariens does not give those figures in the article either, so the owner’s manual or the old pin are the only sources for them.
The pack contents are the third gap. The title and description say “Shear Bolts & Nuts” in a 3 PK, so the nuts appear to be included. The text read does not describe the nut type, and it does not say whether the pack includes a cotter pin or any other hardware.
The details table lists the engine type as “4 Cycle”. That line describes an engine, not a bolt, and it does not make sense for this part. This post does not use it as a fit or compatibility fact.
The warranty is the fourth gap. The listing links to a product warranty page, but the terms are not in the text read. The return policy shown is Amazon’s 30-day voluntary return guarantee.
How we chose
This post covers one product: the Ariens Genuine OEM Ariens 5/16th Deluxe Snow Blower Shear Bolt 52100100, Amazon ASIN B00N25STVC. We did not compare it against other shear pin sets, and the post does not claim it is the best set for every snow thrower. The product data was read from the Amazon listing on 2026-10-23 (CHECKED date). Ratings, seller details and sponsored items on the page are left out, because they are not facts about the part.
The criteria were plain. Does the listing state the model number, pack count, pin size and fit limit? Does the manufacturer describe the same part function and the same check, meaning the owner’s manual part number? Is there a non-retail source on the tool type that a reader can open? The Ariens article is manufacturer support content about shear pins in general. It is not the parts page for part 52100100, and the post says so. The Illinois Extension page covers winter preparation of a snow blower, not shear pins, and it is used only for that general point.
We chose this listing because it is the one assigned for this post, and its fit limit and pack count are the two facts a buyer needs before ordering. Every claim in the post is either a listing fact labelled as the listing’s, an Ariens statement attributed to Ariens, or a general winter-prep point from Illinois Extension. Anything the sources do not say is listed under what we could not verify.
What we could not verify
- Whether this set fits your machine beyond the listing’s pre-2008 limit. The listing gives no model or serial list, and no Ariens parts page for 52100100 was opened.
- Bolt length, thread pitch, material and hardness. The listing does not state them, and the Ariens article does not give them.
- Whether the nuts are the right type for your shear bolt position.
- What the product warranty covers, since its terms were not in the text read.
- Whether the “4 Cycle” engine line is a catalogue error or simply irrelevant to a bolt. Either way, it does not describe this part.
- How many shear pins your machine uses. The Ariens article gives one per side of a two-stage gear case as a general rule, and the owner’s manual is the authority for your unit.
- Whether a worn or broken pin in your own machine matches this part. We did not inspect any machine, so the check is the one Ariens describes: the service parts section of the owner’s manual.
FAQ
Does this shear bolt fit every Ariens snow thrower?
No. The listing rules out pre-2008 Deluxe and Pro units. For a newer machine, Ariens says to reference the service parts section of the owner’s manual to find the correct part number. Check that number before you order.
How many shear pins does a snow blower have?
Ariens says all two-stage snow blowers have at least one shear pin on each side of the auger gear case. The exact count depends on your model, so the owner’s manual is the final source.
Why does a shear pin break on purpose?
Ariens says a shear pin is a weak bolt that connects the auger to the auger shaft. If a large object gets wedged between the augers and the housing, the pin breaks as designed to protect the gearcase from damage.
How tight should the nut be?
Ariens says to tighten the nut to the torque specification in your operator’s manual, or to finger tighten it until the nut no longer spins freely if the manual is not at hand. It also warns against overtightening, because that could stress the pin and cause early failure.
Should you keep spare shear pins?
Yes, according to Ariens, which says it recommends keeping extra shear pins on hand because you never know when you will need them. A three-pack gives you a spare for the next jam.
What should you do before replacing a shear pin?
Ariens says to stop the unit, remove the key and disconnect the spark plug wire from the engine. It also says to move the unit to a warm, enclosed area and wipe the auger shaft clean so you can see and reach the pin. Ariens also says that when a pin breaks, usually only half of it falls out, so you may need to line up the holes in the auger and the shaft and push the rest out with a thin screwdriver. In rare cases, it says, a fairly flat punch and a gentle tap may be needed.
Bottom line
Buy this three-pack only after you confirm from your owner’s manual or your model’s service parts list that your Ariens snow thrower takes the 5/16-inch shear bolt with part number 52100100. If the part number does not match, or the machine is a pre-2008 Deluxe or Pro, skip it.
