Steel Structural Fasteners




Autocraft export lots of fasteners for structural steel work. We select materials strictly conforming to international standards. Products are magnetic particle detected and eddy current sorted after heat treatment. Torque-tension-friction test is done to ensure proper torque coefficient or friction coefficient.
