Description
When you’re installing a heavy-duty pintle hook on your tractor or trailer, you need mounting hardware that’s up to the task. This isn’t the time to raid your old coffee can of random bolts—you need Grade 8 strength and the right size pieces to handle the loads you’ll be pulling. This kit gives you everything you need to properly mount your R20 pintle hook with confidence.
What You’re Getting
- Four Grade 8 hex bolts (9/16″-18 x 2.5″) that won’t stretch or fail under load
- Complete set of flat washers to distribute the mounting force evenly
- Lock washers that keep everything tight even with vibration and heavy use
- Hex nuts sized to match—no hunting around for the right pieces
Built for Real Farm Work
This mounting kit is designed for R20 series rigid mount pintle hooks, which are the workhorses you’ll find on everything from grain trailers to manure spreaders. These hooks handle serious loads, and the hardware needs to match that strength. Whether you’re hauling to the elevator during harvest or moving implements around the farm, this kit keeps your hitch securely mounted.
Made to Last
Grade 8 bolts are what you want for high-stress applications like pintle hook mounting. They’re heat-treated for maximum strength and won’t give up when you’re pulling heavy loads or dealing with the shock loads that come with field work. The washers and nuts are built to the same standards.
Installation Notes
Make sure your mounting surface is clean and flat before installation. Tighten the bolts to the manufacturer’s specifications—usually around 80-90 ft-lbs for this size. Apply a dab of anti-seize compound to the threads if you’re in a corrosive environment or want easier removal later.
