Value Collection R63062326 Button Socket Cap Screw

Product Description

The VALUE COLLECTION R63062326 is a button socket cap screw designed for fastening applications where a low-profile head and high corrosion resistance are required. It features a 1/2-13 UNC thread with a 1-1/4 inch length under the head and is driven by a 5/16 inch hex socket. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this fastener delivers solid corrosion resistance in wet, chemical, or outdoor environments. It conforms to ANSI/ASME B18.3 and carries a 3A thread fit class with right-hand thread direction. Machinists, millwrights, maintenance technicians, and fabricators install this type of fastener across a wide range of mechanical assemblies.

This button socket cap screw is suited for general industrial, commercial, and mechanical applications where a smooth, rounded button head reduces snag risk and allows flush or near-flush installation. Typical use cases include machine guards, equipment panels, brackets, and structural assemblies requiring a clean fastener profile. The stainless steel construction makes it appropriate for food service equipment, marine hardware, and other environments prone to moisture or mild chemical exposure. Minimum order quantity is 5 pieces.
