Product Description

The VALUE COLLECTION MP30135 is a 9/16-12 hex head cap screw made from Grade 5 steel with a zinc-plated finish. It measures 2.5 inches under the head and features partial threading along its shank. The fastener uses a Unified National Coarse (UNC) thread form and conforms to ASME B18.2.1 dimensional standards. This screw is sold in a package of 5 pieces. It is a general-purpose structural fastener suitable for mechanical assemblies, equipment mounting, and maintenance applications across HVAC, plumbing, electrical, and general trade work.

This fastener is appropriate for use in a wide range of commercial and industrial applications where a medium-strength, partially threaded hex cap screw is required. The zinc plating provides basic corrosion resistance, making it suitable for indoor and light-duty outdoor installations. Trade professionals commonly use this size for equipment framing, bracket attachment, and panel mounting in mechanical rooms and utility spaces.
