Value Collection MP97055 Hex Head Cap Screw 3/8-16

Product Description

The VALUE COLLECTION MP97055 is a 3/8-16 hex head cap screw designed for general mechanical assembly and structural fastening applications. The fastener measures 1-1/4 inches under the head and is fully threaded along its entire length, conforming to ASME B18.2.1 dimensional standards. It is manufactured from Grade 5 steel with no surface coating applied, making it suitable for dry indoor environments or applications where a separate coating or treatment will be specified by the installer. This screw is driven with a standard hex wrench or socket and is a common fastener stocked across maintenance, repair, and fabrication shops.

This hex head cap screw is used in a wide range of light to medium-duty mechanical and structural assemblies. Its UNC thread form and 3/8-16 pitch are among the most common inch-series thread combinations found in HVAC equipment frames, plumbing fixture mounting, electrical enclosure hardware, and general equipment fabrication. The fully threaded shank allows full thread engagement even in shorter through-hole and tapped-hole configurations. It is sold in a package quantity of 25 units, making it practical for both single-job use and shop replenishment.
