Value Collection 872255PR Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 872255PR is a hex socket cap screw designed for industrial and mechanical fastening applications. It features a 3/8-16 UNC thread, a 1-inch length under the head, and a 5/16-inch hex drive socket. Constructed from alloy steel with a zinc-plated finish, this fastener delivers solid tensile strength and basic corrosion resistance for general-purpose use. It is fully threaded along its shank, allowing engagement across the entire fastener length. Machinists, maintenance technicians, and assembly professionals install this type of cap screw in equipment frames, jigs, fixtures, and structural assemblies where a recessed drive is required.

This cap screw is suited for medium-duty fastening tasks in manufacturing, mechanical maintenance, and fabrication environments. The 3/8-16 UNC coarse thread pattern is one of the most common inch-series thread standards, making it widely applicable across machine components, structural brackets, and equipment housings. The zinc-plated finish provides a basic barrier against oxidation in dry and mildly humid indoor environments. It is sold in a minimum order quantity of 100 pieces, making it appropriate for production runs, shop stock, or maintenance bin replenishment.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard inch-series tapped holes
• 1-inch length under the head for consistent grip and engagement depth
• 5/16-inch hex socket drive compatible with standard Allen or hex key tooling
• Fully threaded shank for maximum thread engagement across the fastener length
• Alloy steel construction meets ASME B18.8 and ASTM A574 fastener standards
• Zinc-plated finish provides basic corrosion protection in dry indoor environments

Compatibility

Designed as a standard-dimension replacement or stock fastener for any application requiring a 3/8-16 UNC hex socket cap screw with a 1-inch length under the head, conforming to ASME B18.8 and ASTM A574 specifications.

Installation Notes

Installation requires a 5/16-inch hex key or Allen driver; use calibrated torque tooling where joint specifications apply. Ensure the mating tapped hole is clean, properly sized to 3/8-16 UNC, and free of debris before driving the fastener. Do not exceed the rated torque for the alloy steel grade and do not use this fastener in applications requiring stainless steel or elevated-temperature rated materials without confirming suitability. Follow applicable mechanical and structural codes for the specific application.
