Hex Thin Nut

Hex Thin Nuts are high-precision thin-wall hex lock nuts specially designed for limited-space turnout, metro signal and track equipment fastener assemblies.

Ultra-low thickness adapts to narrow installation gaps between base plates, gauge blocks and turnout components, provides stable auxiliary pre-tightening force, avoids height interference during assembly, prevents thread looseness under long-term train vibration, reduces disassembly & readjustment maintenance work for compact metro and turnout track sections.
