Description
When you’re out there running hay equipment, manure spreaders, or other PTO-driven implements, you know how important shearbolts are for protecting your machinery. These bolts are designed to break before expensive gears and shafts do, saving you from major repairs when you hit something hard or your implement jams up. This 10-pack gives you the peace of mind that comes with having spares on hand when you need them most.
What You’re Getting
- Grade 5 hex head bolts that provide consistent breaking strength to protect your equipment
- 5/16″-18 x 2″ size with .312″ shank diameter – the right fit for many New Holland implements
- Zinc-plated hex locknuts that won’t back off under vibration and field conditions
- Plain finish bolts that install easily without binding in threaded holes
- Complete 10-pack so you’ll have extras in the toolbox when the next one breaks
Built for Real Farm Work
These shearbolts are sized for New Holland balers, mowers, spreaders, and other implements where protection of expensive drive components is critical. Whether you’re baling hay, spreading manure, or running a rotary cutter, having the right shearbolts means the difference between a quick roadside fix and a costly trip to the shop.
Made to Last
TISCO builds these bolts to Grade 5 specifications, so they’ll hold up to normal operating loads but still break cleanly when they’re supposed to. The zinc-plated locknuts resist corrosion and stay put, even with all the vibration and weather exposure that farm equipment sees.
Good to Know
Keep a few of these in your toolbox – you never know when you’ll need one in the middle of haying season. When installing, just snug them down hand-tight plus a quarter turn. Over-tightening defeats the purpose and can cause them to break prematurely or not break when they should.
