Nuts for Secure Assembly, Load Distribution and Reliable Long-Term Fastening

Craftsman Hardware supplies a comprehensive range of nuts designed for secure fastening across structural, mechanical, industrial, and general-purpose applications. From standard hex nuts to lock nuts, flange nuts and specialty fastening options, our range helps create strong, serviceable connections across indoor and outdoor environments.

Nuts are essential wherever bolts, threaded rod or machine screws need to be tightened into a secure and dependable assembly. They help maintain clamping force, support load distribution and allow connections to be serviced, adjusted or reassembled when required. Choosing the correct nut type is just as important as selecting the right bolt or thread, especially where vibration, outdoor exposure, repeated movement or heavier structural loading are involved. The right nut improves stability, reduces loosening and helps ensure a safer, longer-lasting installation.

What you’ll find in this range

This range includes standard hex nuts for general fastening, nyloc and lock nuts for vibration resistance, flange nuts for increased bearing area, coupling nuts for joining threaded rod, and specialty nuts for structural, mechanical and installation-specific applications.

Suitable for steelwork, machinery assembly, threaded rod systems, timber and bracket fixing, fabrication, maintenance work and general fastening where strong clamping force and reliable long-term performance are required.
