Secure high-load T-slot setups and fixture assemblies with industrial-grade Nuts (heavy-duty clamping nuts / DIN 6331 collar hex nuts). Heat-treated and hardened for maximum tensile strength, these specialized high collar nuts feature an integrated wide washer flange and precision-cut metric internal threads (1.5d height). Designed specifically for heavy machine tool workholding, the wide collar face eliminates the need for separate loose washers, distributing tightening torque evenly to prevent surface marring on clamp straps and fixtures under high bolt loads.
