Value Collection 36876 Flat Socket Cap Screw 3/8-24 X 1-1/2 in

Product Description

The VALUE COLLECTION 36876 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head driven by a 7/32-inch hex socket and is fully threaded along its 1-1/2-inch overall length. The 3/8-24 UNF thread specification suits fine-thread assemblies where vibration resistance or precise clamp load is important. Machined from alloy steel and finished with a black oxide coating for moderate corrosion resistance, this screw is appropriate for mechanical assemblies, fixtures, and tooling installations performed by machinists, millwrights, and maintenance technicians. Each package contains 25 pieces.

This screw is suited for use in precision mechanical assemblies, jigs, fixtures, machine frames, and similar industrial or commercial applications where a low-profile, flush-seating fastener is required. The fine UNF thread pitch makes it a common choice in applications involving thin materials or where fine thread engagement is preferred over coarse UNC alternatives. It is sold in a package quantity of 25, making it practical for bench stock, job kits, or small-batch production builds.

Key Features

• 82-degree flat head seats flush in countersunk holes for a low-profile, snag-free installation
• 7/32-inch hex socket drive for use with standard Allen keys or hex bit drivers
• 3/8-24 UNF fully threaded 1-1/2-inch length provides maximum thread engagement
• Alloy steel construction delivers high tensile and shear strength for demanding mechanical applications
• Black oxide finish provides mild corrosion resistance and reduces light reflection in tooling environments
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any countersunk hole pattern machined to ASME/ANSI B18.3 specifications with a 3/8-24 UNF tapped hole.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a calibrated torque wrench with a 7/32-inch hex bit. Always ensure the mating tapped hole conforms to 3/8-24 UNF thread specifications before installation. De-energize, depressurize, or lock out any equipment before fastener replacement in live assemblies. Do not substitute coarse-thread (UNC) hardware in fine-thread (UNF) tapped holes.
