Value Collection 30065 Hex Cap Screw 3/8-16 X 3.5 in Grade 5 25pk

Product Description

The VALUE COLLECTION 30065 is a 3/8-16 hex head cap screw sized at 3.5 inches under head, manufactured from Grade 5 steel with a zinc-plated finish. Designed to the ASME B18.2.1 standard, this screw features a Unified National Coarse (UNC) thread form and is partially threaded along its shank. The zinc plating provides a baseline level of corrosion resistance suitable for general indoor and light-duty outdoor mechanical assemblies. This fastener is sold in a pack of 25 and is a standard choice for structural and mechanical connections across HVAC, plumbing, electrical, and general equipment installation work.

This screw is appropriate for use in a wide range of trade applications where a 3/8-16 UNC fastener is required. Common uses include equipment mounting, bracket assembly, panel attachment, and general mechanical fastening in residential and light commercial installations. The partial threading on the shank allows for a stronger clamping grip in applications where the unthreaded shank passes through a clearance hole before engaging a tapped hole or nut.

Key Features

• 3/8-16 UNC thread size for broad compatibility with standard tapped holes and nuts
• 3.5 inches length under head for applications requiring extended reach through stacked materials
• Grade 5 steel construction for medium-strength structural fastening
• Zinc-plated finish provides baseline corrosion resistance
• Partially threaded shank improves clamping force in clearance-hole applications
• Manufactured to ASME B18.2.1 dimensional standards
• Sold in a pack of 25 to support job-site quantities

Compatibility

Designed as a standard 3/8-16 UNC hex head cap screw conforming to ASME B18.2.1, suitable for use wherever a Grade 5 steel partially threaded hex cap screw of this thread size and length is specified.

Installation Notes

Installation is performed with a standard hex wrench or socket driver sized for a 3/8-inch hex head cap screw. Ensure the mating tapped hole or nut is clean and free of debris before fastening. Always torque to the specification called out in the equipment or assembly documentation for Grade 5 fasteners of this diameter. Power down or de-energize any equipment before accessing fastened panels or structural assemblies.
