Product Description

The AU-VE-CO PRODUCTS 23662 is a hex head cap screw sized 5/16-18 x 15/16 inches, manufactured from steel with a black oxide finish. This standard inch-series fastener features a 1/2-inch hex drive head and a unified coarse thread (UNC) pitch of 18 threads per inch on a 5/16-inch nominal diameter shank. The black oxide coating provides mild corrosion resistance and reduces light reflection. It is used across HVAC, plumbing, electrical, and general mechanical assembly applications wherever a reliable steel cap screw is needed. Installation is performed by any qualified technician or mechanic using standard hand or power tools.

This screw is suited for light-to-medium fastening applications in residential and commercial trade work. Common uses include securing brackets, panels, equipment housings, and structural components in HVAC equipment, electrical enclosures, and plumbing assemblies. The 5/16-18 UNC thread pattern is one of the most widely standardized sizes in inch-system mechanical work, making this screw a frequent go-to for service and repair tasks across multiple trades. Sold individually with a minimum order quantity of 50 units.
