Description

You know that feeling when you’re working on a piece of equipment and you need a fastener that won’t back out no matter how much vibration it sees. That’s where this keps nut comes in handy—it’s got built-in external teeth that bite into whatever surface you’re clamping against, giving you extra holding power that standard nuts just can’t match.

What You’re Getting

Built-in external tooth washer eliminates the need for separate washers
Zinc plating protects against rust and corrosion in outdoor conditions
5/16-18 UNC thread fits standard bolts and studs
Self-locking design resists loosening from vibration and temperature cycling

Built for Real Farm Work

This versatile fastener works great on cultivators, planters, mowers, and any equipment where you need a secure connection that won’t walk loose. The external teeth distribute clamping force while preventing rotation, making it perfect for attaching guards, brackets, and panels on farm machinery that sees constant jarring and vibration.

Made to Last

The zinc finish gives you reliable corrosion protection so these nuts will look good and perform well season after season. The integrated washer design means fewer parts to keep track of and no chance of losing washers when you’re working in the field.

Good to Know

The external teeth will mark softer surfaces like aluminum or painted steel, which is normal and actually helps prevent loosening. Thread it on finger-tight first, then use a wrench to snug it down—the teeth will bite in as you tighten. No need to overtighten since the locking action starts as soon as the washer contacts the surface.
