Value Collection 872295PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 872295PR is a hex socket cap screw designed for precision fastening applications requiring controlled torque and a flush or low-profile head. Built from alloy steel with a zinc-plated finish for corrosion resistance, this fastener measures 1.5 inches in length under head and accepts a 5/16-inch hex drive. The 3/8-24 UNF thread pitch is a fine-thread specification, suited for applications where vibration resistance and precise clamping force are priorities. It meets ASME B18.8 and ASTM A574 standards. Installation requires a hex key or Allen-type driver. Typically installed by machinists, millwrights, and mechanical contractors in equipment assembly and maintenance.

This screw is appropriate for use in mechanical assemblies, fixtures, tooling, and equipment where a recessed-drive cap screw is specified. The fine 3/8-24 UNF thread engages cleanly in tapped holes or threaded inserts in steel, aluminum, and other engineering materials. Full threading along the shank allows maximum thread engagement across the full 1.5-inch length under head, making it a practical choice for through-hole and blind-hole applications where grip length must be maximized. Sold in a minimum order quantity of 10 pieces.

Key Features

• 3/8-24 UNF fine-thread specification for vibration-resistant clamping
• Fully threaded shank for maximum thread engagement across the full length
• 5/16-inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 mechanical requirements
• Zinc-plated finish provides basic corrosion protection in dry indoor environments
• Conforms to ASME B18.8 dimensional standards

Compatibility

Designed as a standard ASME B18.8 hex socket cap screw for use in any application requiring a 3/8-24 UNF fully threaded fastener with a 5/16-inch hex drive.

Installation Notes

Installation requires a 5/16-inch hex key or socket-style Allen driver rated for the torque demand of the application. Confirm that the mating tapped hole or threaded insert is cut to 3/8-24 UNF specification before installation. Inspect threads for debris or damage prior to assembly. Do not exceed the rated proof load of the fastener or substitute this fine-thread screw in applications specifying coarse-thread UNC hardware without verifying thread compatibility.
