6mm Snow Blower Shear Pin for Auger Protection
This is a 6mm OD shear pin for snow blower augers, sold to dealers, rental fleets and importers who have to keep machines running through a season. The shear pin is designed to break when the auger hits a kerb stone, a frozen newspaper or a buried step, sacrificing a cheap pin instead of the auger gearbox behind it, which means it is a consumable rather than a failure. The practical problem is that operators replace broken pins with whatever bolt is in the toolbox, and a hardened bolt will not shear, so the next impact goes straight into the gearbox. SONJUN offers the full accessory range for its snow blowers, so a fleet can be supplied with the correct pin in quantity and keep spares on the machine.
- Sacrificial pin that breaks before the auger gearbox does, which is the expensive part behind it
- 6mm OD supplied as the correct pin rather than a substitute bolt from the toolbox
- Low value consumable that can be bought in quantity and carried on every machine
- Ordered against the machine model from its manufacturer rather than cross referenced
- Sample orders accepted so fitment can be confirmed before stocking depth
- Warranty quality failures replaced free of charge; out of warranty parts sold at cost price

Application Scenarios
- Mid route repair when the auger has stopped turning after hitting a buried obstruction
- Pre season stocking so every machine in a fleet carries spare pins on board
- Rental fleets where untrained operators regularly find the kerb under the snow
- Dealers supplying a pack of pins with every machine sold
- Importers stocking a fast moving consumable alongside the machine range
Who It Is For
- Importers and distributors of snow throwers running a parts programme
- Service dealers and small engine repair workshops
- Equipment rental companies maintaining their own fleet
- Municipal and facility maintenance workshops
- Online spare parts and consumables resellers
Problems It Solves
- Operators fit a hardened bolt in place of a shear pin, so the next impact destroys the auger gearbox
- A machine with a sheared pin and no spare on board is stranded mid route in a snow event
- An auger that will not turn is often misdiagnosed as a belt or transmission fault
- Sourcing the correct pin locally means matching a diameter off a broken half
- Buying a fast moving consumable from a third party adds a supplier and a shipment

How It Compares
Against A standard hardware bolt
A hardened bolt will not shear on impact, so the load goes into the auger gearbox instead. The shear pin is meant to be the part that fails.
Against Replacing the auger gearbox
A gearbox repair is the outcome the shear pin exists to prevent, and costs many times what a stock of pins does.
Against Buying pins from a local fastener supplier
A local supplier matches on diameter alone and cannot confirm shear behaviour. This pin is supplied at 6mm OD against the machines it belongs to.
Use Guide
- Stop the engine and disconnect the spark plug lead before going near the auger
- Clear the obstruction that broke the pin before fitting the replacement
- Drive out both halves of the old pin so the new one seats fully in the bore
- Fit only the correct shear pin, never a hardened bolt, or the next impact will reach the gearbox
- Carry spare pins on the machine so a shear does not end the route

How to Choose a Snow Thrower for a Commercial Clearing Route
Clearing width, intake height and drive type decide how long a fixed route takes. Here is how to specify a machine against the route rather than against a brochure.
