MIDWEST FASTENER CORP 53675 Nylon Insert Lock Nut M16-1.50 Steel Class 8 Yellow

MIDWEST FASTENER Nylon Insert Lock Nut

This M16-1.50 steel lock nut uses a nylon insert to resist loosening caused by vibration and torque. It is rated Class 8 for strength and finished in yellow zinc. The part suits automotive, industrial and general mechanical assemblies where fastener security is critical. Sold individually under manufacturer part number 53675.

Replaces standard hex nuts in vibration-prone joints

A plain hex nut can back off when subjected to repeated shock or cyclic loading. The nylon insert creates prevailing torque that maintains clamp force without additional locking hardware. The upgrade is worthwhile whenever disassembly for re-torquing is impractical or when joint failure carries safety or downtime costs.

Suits mechanics and engineers securing M16 threads

Buyers needing a reusable, all-metal prevailing-torque nut or a higher temperature rating should look elsewhere. The nylon insert limits service temperature and is not intended for repeated removal cycles. Applications requiring left-hand threads, fine-pitch variants other than 1.50 mm, or non-steel materials are not served by this item.
