Description

When you’re putting together heavy equipment or repairing something that needs to stay put, you want a bolt that can handle serious loads. This 7/8-inch hex bolt gives you the muscle for heavy-duty connections where standard fasteners just won’t cut it. The UNF (Unified Fine) thread pattern provides better holding power and resistance to vibration than coarse threads—exactly what you need when things are bouncing around in rough field conditions.

What You’re Getting

  • Heavy-duty 7/8-inch diameter provides exceptional strength for demanding applications
  • Fine UNF thread pattern offers superior holding power and vibration resistance
  • Zinc plating protects against rust and corrosion in outdoor conditions
  • 3-inch length perfect for through-bolting thick components or multiple pieces
  • Professional-grade construction built to handle agricultural and industrial loads

Built for Real Farm Work

This size bolt is what you reach for when you’re working on the heavy stuff—loader brackets, three-point hitch assemblies, cultivator frames, or any custom fabrication project that needs serious holding power. The 7/8-inch diameter and fine threads make it ideal for applications where you can’t afford to have things come loose during operation.

Made to Last

The zinc plating gives you corrosion protection that stands up to weather, chemicals, and the general abuse that farm equipment takes. UNF threads are machined to tighter tolerances than coarse threads, so you get better thread engagement and a more secure connection that won’t work loose under vibration.

Good to Know

UNF threads require the matching fine-thread nut—don’t try to use a standard coarse thread nut with this bolt. Take your time threading it on, as fine threads can cross-thread easier than coarse ones. A little anti-seize compound on the threads helps prevent galling and makes future removal easier.
