Value Collection 403100PR Hex Head Cap Screw 3/8-16 X 7/8 in

Product Description

The VALUE COLLECTION 403100PR is a fully threaded hex head cap screw designed for general-purpose fastening in mechanical, structural, and equipment assembly applications. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener measures 3/8-16 thread size with a 7/8-inch length under head. The zinc plating provides basic corrosion resistance suitable for indoor and light-duty outdoor environments. Installation requires a 9/16-inch hex wrench or socket. This fastener follows the Unified National Coarse (UNC) thread standard and is sold in multiples of 100 units per order.

This cap screw is suited for light to medium-duty fastening tasks across a wide range of trades and industries, including HVAC equipment assembly, plumbing fixture mounting, electrical panel fabrication, and general mechanical work. The 3/8-16 UNC thread pitch is one of the most common inch-system thread standards, making this fastener a practical stock item for shops, service vehicles, and maintenance facilities. It is appropriate for use in non-critical structural connections where Grade 2 steel meets the load requirements of the application.
