Product Description

The M12 Combination Lock Nut Set is a heavy-duty 140mm Threaded Fastener Kit designed for industrial stability, featuring a Secure Locking Nut Assembly with M12×140 threading for permanent vibration-resistant connections. This set operates within -40°C to 120°C and withstands harsh environments in machinery, automotive, and construction sectors. The zinc-plated steel construction ensures corrosion resistance, while the dual-nut design combines a standard hex nut with a locking flange for tamper-proof security. Though requiring compatible M12 threaded rods and a 19mm wrench for installation, its reinforced grip prevents loosening under dynamic loads. The kit's 140mm thread engagement depth optimizes load distribution, making it ideal for structural joints, equipment bases, and high-stress fastener applications where reliability is critical. Primary drawbacks include bulkier profile compared to standard nuts and restricted accessibility in confined spaces.
