Value Collection 90408 Hex Head Cap Screw 1/4-20 Brass

Product Description

The VALUE COLLECTION 90408 is a brass hex head cap screw threaded to the 1/4-20 Unified National Coarse (UNC) standard with a length under head of 1-3/4 inches and a 7/16-inch hex drive. Brass construction provides natural corrosion resistance, making this fastener suitable for applications where galvanic compatibility with copper, bronze, or similar alloys is required. The external hex drive accommodates standard wrenches and sockets. This screw is sold in packs of 100, making it practical for production assembly, service kits, and maintenance stock.

This fastener is used across a broad range of trade and light industrial applications including HVAC equipment assembly, electrical enclosure mounting, plumbing fixture installation, and general mechanical assembly where a non-ferrous, corrosion-resistant fastener is specified. The 1/4-20 UNC thread is one of the most common inch-series thread forms and mates with standard 1/4-20 nuts, threaded inserts, and tapped holes found throughout commercial and residential equipment.
