Value Collection 30069 Hex Head Cap Screw 3/8-16 X 5-1/2 in 25pk

Product Description

The VALUE COLLECTION 30069 is a 3/8-16 UNC hex head cap screw measuring 5-1/2 inches under the head, manufactured from Grade 5 steel with a zinc-plated finish. Partially threaded along the shank, this fastener is designed for through-bolt and structural clamping applications where a grip zone is required. The zinc plating provides baseline corrosion resistance suitable for indoor and sheltered outdoor installations. Sold in a package of 25, this screw meets ASME B18.2.1 dimensional standards and is appropriate for use by maintenance technicians, HVAC mechanics, plumbers, and general tradespeople working on equipment mounting, framing, and mechanical assembly tasks.

This cap screw is well suited for equipment bases, structural brackets, duct hangers, pipe supports, and general mechanical assemblies in residential and light commercial settings. The 3/8-16 thread size is one of the most common fastener specifications in trade work, making this screw a reliable bench stock item for service vans and shop inventory. The partial threading allows the unthreaded shank to align mating components before the thread engages, which is useful in precision clamping and pivot applications.

Installation Notes

Installation should be performed with a properly sized hex wrench or socket drive rated for the fastener torque class. Ensure mating threads are clean and free of debris before installation. Always consult applicable mechanical codes or equipment manufacturer torque specifications when fastening structural or pressure-bearing components. Do not use impact tools at full speed on unlubricated threads, as this can damage the zinc coating and thread form.
