Description

You know how frustrating it can be when hydraulic connections work loose and start leaking right in the middle of a busy day. These self-locking hex nuts keep hydraulic fittings snug and secure, so you can focus on getting work done instead of chasing down leaks and retightening connections.

What You’re Getting

Self-locking design that won’t back off from vibration and normal use
Precise 1/4″-28 threads that fit standard hydraulic fittings perfectly
Pack includes 4 nuts – enough for a typical hydraulic repair or installation
Built to handle the pressure and temperature swings of hydraulic systems

Built for Real Farm Work

These nuts are designed for Massey Ferguson hydraulic systems and other tractor brands that use standard 1/4″-28 threaded hydraulic fittings. Whether you’re working on hydraulic cylinders, control valves, or auxiliary outlets, these nuts provide the secure connection you need for reliable operation.

Made to Last

Hydraulic systems put a lot of stress on connections – high pressure, constant vibration, and temperature changes from hot summer days to cold winter mornings. These self-locking nuts are built to handle all of that without loosening up on you when you need them most.

Good to Know

The self-locking feature means these nuts grip tight once you get them snug – no need to over-tighten and risk stripping threads. When installing, thread them on by hand first to avoid cross-threading, then use a wrench to snug them down. The locking action engages automatically.
