Description
You know how regular nuts can work themselves loose after a few hours of fieldwork—rattling around, vibrating free, and leaving you with a loose implement when you least expect it. That's where this 3/8" nylock flange nut comes in handy. The built-in nylon insert grips the bolt threads and won't let go, even when your equipment is bouncing through rough ground or running at full throttle.
What You're Getting
- Self-locking nylon insert that prevents vibration loosening without needing thread locker
- Integrated flange distributes load over a wider area than regular nuts
- Zinc plating resists corrosion from moisture, fertilizer, and chemical exposure
- Can be removed and reused multiple times while keeping its locking power
Built for Real Farm Work
This fastener is perfect for securing cultivator points, mower blades, implement attachments, and hydraulic fittings on tractors and farm equipment. The flange design works especially well where you need to distribute clamping force across thinner materials or where a washer might slip out of place during assembly.
Made to Last
The nylon collar insert deforms slightly over the threads as you tighten it down, creating consistent friction that locks the nut in place. Unlike thread-cutting lock nuts, this design won't damage your bolt threads and maintains its grip through countless vibration cycles that would shake loose a standard nut.
Good to Know
These thread on with a bit more resistance than regular nuts—that's the nylon insert doing its job. Tighten to normal torque specs for 3/8" hardware, but don't over-torque or you'll crush the nylon and lose the locking action. Keep a few extras in your toolbox since they're one of those parts you always seem to need when you're in the middle of a repair.
