Value Collection 36870 Flat Socket Cap Screw 3/4-10

Product Description

The VALUE COLLECTION 36870 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head with a 1/2-inch hex socket drive, allowing installation with a standard hex key or Allen wrench. The screw is fully threaded along its 1-1/4-inch overall length with a 3/4-10 UNC thread size. Constructed from alloy steel with a black oxide finish, it provides moderate corrosion resistance and reduced light reflection. This fastener meets ASME/ANSI B18.3 and ASTM F835 standards. It is sold in packages of 10 units.

This flat socket cap screw is suited for mechanical assemblies, fixtures, and structural connections where the fastener head must sit flush with or below the mating surface. The coarse UNC thread pattern makes it well suited for use in steel, cast iron, and similar ferrous base materials. It is commonly used in industrial equipment, tooling fixtures, machine frames, and general fabrication work where a recessed drive fastener is required. Licensed tradespeople and industrial maintenance technicians are the primary installers.

Compatibility

Designed as an OEM-style replacement or standard-spec fastener for assemblies requiring a 3/4-10 UNC fully threaded flat socket cap screw conforming to ASME/ANSI B18.3 and ASTM F835 specifications.

Installation Notes

Install using a calibrated torque wrench with the appropriate 1/2-inch hex bit to avoid rounding the socket drive. Ensure the mating countersink is machined to an 82-degree angle to achieve full head seating. Confirm thread engagement depth meets design requirements before final torque. Follow applicable mechanical and structural codes for the specific application.
