Value Collection MP30027 Hex Cap Screw 5/16-18 X 3/4 in Grade 5

Product Description

The VALUE COLLECTION MP30027 is a 5/16-18 x 3/4 inch hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. Fully threaded with a Unified National Coarse (UNC) thread form, it meets ASME B18.2.1 dimensional standards. This fastener is used across a wide range of mechanical assembly, structural, and equipment maintenance applications where a reliable, mid-strength threaded fastener is required. Installation is performed with a standard hex wrench or socket driver. Packaged in quantities of 50 per pack, it is suited for shops and field technicians who need reliable general-purpose hardware on hand.

This screw is appropriate for use in HVAC equipment assembly, plumbing fixture mounting, electrical panel and enclosure work, and general mechanical fastening tasks. The zinc plating provides a basic level of corrosion resistance for indoor and light-duty outdoor applications. The fully threaded body allows maximum thread engagement over the entire 3/4 inch length under head, making it well-suited for fastening into tapped holes or with a nut where full grip length is needed.
