Lock nuts are essential in applications where vibration or movement could cause standard nuts to loosen. POLT24 offers several locking solutions:
DIN 985 nylon-insert nuts for everyday reliability
DIN 7967 all-metal lock nuts for high-temperature and harsh environments
DIN 439 thin lock nuts (jam nuts) for low-profile or double-nut assemblies
Widely used in automotive, machinery, and industrial equipment, these nuts ensure secure fastening even under heavy vibration and demanding operating conditions.
