Holo-krome 64010 Button Socket Cap Screw 6-32 3/8 in

Product Description

The HOLO-KROME 64010 is a button head socket cap screw designed for applications where a low-profile, high-strength fastener is required. It features a 6-32 UNC thread with a class 3A fit and is fully threaded along its 3/8-inch length under head. The hex socket drive measures 5/64 inches and accepts a standard hex key. Manufactured from alloy steel with a black oxide finish, the fastener achieves a hardness of 38 HRC, making it suitable for demanding mechanical assemblies. Machinists, maintenance technicians, and fabricators install this screw in panel mounting, machine guarding, and precision equipment applications.

This button socket cap screw is suited for general mechanical and industrial assembly work where a flush, rounded head profile reduces snagging and interference with adjacent components. The black oxide finish provides mild corrosion resistance and a uniform dark appearance. Its right-hand thread direction and ANSI/ASME B18.3 and ASTM F835 compliance make it a standard-conforming choice for controlled assemblies. Sold individually, with a minimum order quantity of 100 pieces per order.

Compatibility

Designed as a standard 6-32 UNC button socket cap screw conforming to ANSI/ASME B18.3 and ASTM F835, suitable for use in any application accepting a 6-32 threaded fastener with a button head profile.

Installation Notes

Install with a 5/64-inch hex key or matching socket bit driver. Ensure mating threads are clean and free of debris before driving. Follow applicable torque guidelines for class 3A alloy steel fasteners as specified by ANSI/ASME B18.3 or the equipment manufacturer. Do not exceed the rated torque for the thread size, as over-tightening can strip threads or deform the button head.
