Overview

These Nyloc nuts conform to DIN 985 (also aligned with ISO 10511), offering a self-locking function through an integrated nylon collar that provides prevailing torque and resists loosening due to vibration. ([turn0search7], [turn0search3])

Material & Locking Mechanism

  • Material: Typically, high-tensile carbon steel (Grade 4 or Grade 8), zinc plated for corrosion protection and a bright finish. ([turn0search5], [turn0search3], [turn0search4])

  • Locking Feature: A nylon insert at the top of the nut slightly deforms over the bolt threads, creating a secure, non-permanent jam fit for vibration resistance. ([turn0search3], [turn0search11])
