Value Collection D30056 Hex Head Cap Screw 3/8-16

Product Description

The VALUE COLLECTION D30056 is a 3/8-16 hex head cap screw designed for general mechanical fastening in trade and industrial applications. Manufactured from Grade 5 steel with a zinc-plated finish, this screw delivers solid tensile strength for mid-duty bolted connections. The partially threaded shank provides a smooth bearing surface under the head, which is useful when clamping materials without thread engagement across the full grip length. At 1.5 inches in length under head, it fits a wide range of standard structural and equipment assemblies. Produced to ASME B18.2.1 dimensional standards, it meets the tolerances expected on professional jobsites and in fabrication shops.

This fastener is suited for residential and commercial mechanical, HVAC, plumbing, and electrical installations where 3/8-inch UNC threaded connections are required. Plumbers, HVAC technicians, electricians, and general contractors use cap screws of this type to secure equipment brackets, pipe hangers, control panels, and structural framing components. The zinc plating provides basic corrosion resistance in indoor and moderately protected outdoor environments. Minimum order quantity is 25 pieces per order.

Key Features

• Grade 5 steel construction for reliable mid-duty tensile and shear strength
• Zinc-plated finish for basic corrosion resistance in protected environments
• Partially threaded shank per ASME B18.2.1 dimensional standards
• 3/8-16 UNC thread for compatibility with standard inch-series nuts and tapped holes
• 1.5 inches length under head suits a broad range of fastening applications

Compatibility

Designed as a standard inch-series hex head cap screw for use with 3/8-16 UNC tapped holes, nuts, and threaded inserts in steel, aluminum, and similar substrates.

Installation Notes

Installation is performed by mechanical, HVAC, plumbing, or electrical tradespeople using a standard 9/16-inch hex wrench or socket. Always de-energize equipment and relieve system pressure before fastening or removing hardware on active mechanical systems. Use the appropriate flat washer and nut to distribute clamp load and prevent surface damage. Do not exceed the torque rating appropriate for Grade 5 fasteners at this thread size as specified by the equipment manufacturer or applicable code.
