Dorman 432-007 Hex Lock Nut with Nylon Insert Class Height - M7-1.0 8 7mm

The Dorman 432-007 is a Class 8 metric hex lock nut featuring an integrated nylon ring insert, designed to provide reliable vibration-resistant fastening in automotive, powersports, and general-purpose applications. With a thread size of M7-1.0 (7mm diameter, 1.0mm pitch) and a height of 7mm, this nut meets standard DIN metric specifications.

The nylon insert creates friction against the mating bolt threads, preventing the nut from loosening due to vibration, torque fluctuation, or thermal cycling — making it a trusted solution for demanding under-hood and chassis applications.
