Professional Applications & Engineering Value

This M45x3mm nylon insert lock nut delivers critical vibration resistance in demanding industrial applications where loosening under dynamic loads poses significant safety and operational risks. The zinc-plated steel construction provides essential corrosion protection for machinery exposed to moisture, chemicals, or outdoor elements, while the fine metric thread pitch ensures superior clamping force distribution across mating surfaces. Engineered with a Class 8 strength rating, this lock nut maintains integrity in high-torque applications common in heavy machinery, construction equipment, and automotive assemblies. The nylon insert locking technology creates consistent friction against bolt threads, eliminating the need for secondary locking devices and reducing maintenance frequency in vibration-prone systems.

Specification Summary & Compliance

This lock nut features M45x3mm fine metric threads with Class 6H thread fit tolerance ensuring precise engagement with mating components. Manufactured to ISO 10511 and DIN 985 standards for dimensional accuracy and performance consistency. The zinc-plated steel construction meets RoHS 3 (2015/863/EU) compliance for environmental safety. With 70mm hex width and 45mm height, this external hex drive lock nut provides standard tool compatibility while delivering Class 8 mechanical properties for high-strength applications requiring reliable, reusable locking performance.
