Value Collection 201169PR Button Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 201169PR is a button socket cap screw designed for applications requiring a low-profile fastener with high tensile strength. Made from alloy steel with a black oxide finish, it features a 3/8-16 UNC thread and measures 5/8 inches under the head. Drive engagement is through a 7/32 inch hex socket. Hardness is rated at 36-43 HRC, making it suitable for demanding mechanical assemblies. This fastener meets ANSI/ASME B18.3 and ASTM F835 standards and is fully threaded with a right-hand thread direction. Machinists, millwrights, and mechanical contractors typically install this type of fastener in structural and equipment assemblies.

This screw is used in general industrial, manufacturing, and equipment fabrication applications where a button-head profile is needed to reduce snag points or clear adjacent components. The black oxide coating provides mild corrosion resistance and a low-reflectance finish suitable for both indoor mechanical assemblies and lightly protected environments. Thread Fit Class 3A ensures close tolerance engagement for consistent clamping force. It is sold individually with a minimum order quantity of 100 pieces.

Compatibility

Designed as an OEM-style and general-purpose replacement or new-installation fastener for any assembly requiring a 3/8-16 UNC button socket cap screw with a 5/8 inch grip length and black oxide finish.

Installation Notes

Installation requires a 7/32 inch hex key or hex socket bit. Ensure mating threads are clean and free of debris before installation. Torque to the fastener manufacturer or equipment OEM specification for the given application and material stack. Always de-energize or lock out equipment before fastener service on mechanical assemblies.
