Keps (K) Nut

🔩 Keps Nut (K Nut)

(Pre-Assembled Locking Nut with Free-Spinning Washer for Fast Assembly)

Neo Fasteners supplies high-performance Keps Nuts, also known as K Nuts, which are hex nuts pre-assembled with a free-spinning lock washer. This integrated design simplifies installation, improves assembly speed, and provides a reliable locking mechanism against vibration and loosening.

Ideal for mass production, field assembly, and maintenance tasks, Keps Nuts reduce part handling and improve consistency in high-volume mechanical, electrical, and automotive applications.

🔹 Product Overview:

A Keps Nut consists of a hex nut combined with a captivated external tooth lock washer, permanently attached so the washer stays in place. As the nut is tightened, the lock washer bites into the mating surface, offering enhanced resistance to loosening under vibration.

This all-in-one fastening solution reduces labor costs, speeds up assembly lines, and ensures consistent locking force across installations.
