Value Collection 837259PR Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 837259PR is a hex socket cap screw designed for secure fastening in mechanical, structural, and industrial assemblies. Sized at 3/8-16 UNC with a 1-1/2-inch length under head, this fully threaded fastener accepts a 5/16-inch hex drive. Constructed from alloy steel with a zinc-plated coating that meets ASTM B695, it offers corrosion resistance suited for general shop and field applications. Weighing approximately 0.01 pounds per piece, it is a compact, high-strength fastener used across a wide range of trade and manufacturing contexts.

This fastener is appropriate for use in HVAC equipment assembly, plumbing fixture mounting, electrical enclosure fabrication, and general mechanical maintenance. The 3/8-16 UNC thread form is a standard coarse-thread designation, making it broadly compatible with tapped holes and nuts conforming to that specification. The fully threaded shank provides maximum thread engagement throughout the clamping length, which is advantageous in thinner materials or shallow tapped holes. Installers in light fabrication and equipment service will find this a commonly stocked fastener size.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• 1-1/2-inch length under head with fully threaded shank for maximum thread engagement
• 5/16-inch hex socket drive for use with standard hex keys or Allen-type drivers
• Alloy steel construction provides high tensile strength for demanding fastening applications
• Zinc-plated coating meets ASTM B695 for improved corrosion resistance in typical indoor environments

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw suitable for any application requiring that thread size, a 1-1/2-inch clamping length, and a 5/16-inch hex drive.

Installation Notes

Install using a calibrated hex key or socket driver sized to 5/16 inch. Ensure the mating tapped hole or nut conforms to 3/8-16 UNC specification before installation to avoid cross-threading. De-energize or depressurize any system before fastener service where the joint is part of an energized or pressurized assembly. Follow applicable mechanical codes and equipment manufacturer guidelines for torque requirements specific to the assembly.
