Protect Auger Gearboxes & Eliminate Winter Downtime: Genuine MTD Shear Bolt Kit

Eliminate shattered brass worm gears, bent auger drive shafts, and blizzard downtime on your two-stage snow blower. This Genuine MTD / Troy-Bilt Factory OEM Shear Bolt Kit (Part Number OEM-710-0890) is the authentic mechanical protection hardware pack engineered explicitly for MTD, Troy-Bilt, Yard Machines, Cub Cadet, and Craftsman two-stage snow throwers (2004 & prior with 3/4" auger shafts, directly replacing part numbers 710-0890, 910-0890A, and 712-0158 lock nuts) . Operating a snowblower with standard grade-5 or grade-8 hardware-store bolts bypasses your machine's primary safety defense, turning a minor ice jam into a catastrophic gearbox rebuild.

Precision-engineered by MTD, each shear bolt in this kit is manufactured with specialized shear grooves machined into the shank to provide a calibrated breaking threshold. When the auger strikes a frozen obstacle, the bolt instantly shears clean across the relief groove, disengaging the auger flight in milliseconds and saving the internal bronze gear and cast aluminum gearcase from shock damage. Each bolt is forged with standard 5/16"-18 threads and a 1.5-inch length, finished in a corrosion-resistant yellow dichromate plating to resist road salt and slush, and paired with factory Grade-5 nylon-insert lock nuts (712-0158) that resist vibration loosening in sub-zero working conditions.

This authentic factory replacement hardware kit is cataloged under MTD / Troy-Bilt OEM Part Number OEM-710-0890 (OEM7100890 / 710-0890 / 910-0890A / 712-0158 / Kit, Shear Pin / Auger Shear Bolts) .

Why This Genuine MTD OEM-710-0890 Kit is the Pro Standard:

🛠️ Pro-Maintenance Tip: Watch the "Auger Shaft Anti-Seize Lube & Nut Tightening Secret!" Anti-Seize Secret: Every time you replace a sheared bolt (or during pre-season servicing), remove the remaining bolt piece and pump grease into the auger zerk fittings while spinning the auger flight by hand! If your auger is rusted to the center shaft, it will never spin freely when a shear pin breaks, transferring the impact shock into the gearbox anyway. Coating the auger shaft with marine grease or anti-seize ensures the shear pin functions as designed. Torque Secret: Never over-tighten the 712-0158 lock nuts! Tighten the lock nut only until the nylon engages and the nut is snug against the auger collar with minimal play. Over-torquing pre-stresses the shear groove, causing the bolt to snap prematurely under ordinary wet snow loads.
