Rohs/Reach Compliant/Halogen Free Compliance A socket cap screw, also known as a socket head cap screw, socket screw, or Allen bolt, is a type of cap screw with a cylindrical head and hexagonal drive hole. The term socket head cap screw typically refers to a type of threaded fastener. Forged heat-treated alloy examples are high strength fasteners intended for the most demanding mechanical applications, with special alloy formulations available that are capable of maintaining strength at temperatures in excess of 1000 degrees F (587 degrees C). A hex key (sometimes referred to as an Allen wrench or Allen key) or hex driver is required to tighten or loosen a socket screw. Socket head cap screws are commonly used in assemblies that do not provide sufficient clearance for a conventional wrench or socket.

Screw Lock Washer Customized/ISO/DIN/GB/IFI Standard 1. Material: Steel, Alloy steel, Stainless steel, Brass, Copper  2.

Rohs/Reach Compliant/Halogen Free Compliance The Square Cone washer (Square Dome) absorbs high installation torques, generates and sustains tension, distributes the load and spans oversize holes. Replaces three parts: screw, flat washer and helical washer, in many applications. The unique washer on this assembly combines the tension generating characteristics of a spring washer with the locking tension of the helical washer to increase shock absorption and vibration resistance.
