Value Collection 36873 Flat Socket Cap Screw 3/8-24 X 3/4 in 25pk

Product Description

The Value Collection 36873 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Manufactured from alloy steel with a black oxide finish, this screw features an 82-degree flat head and a 7/32-inch hex socket drive. The 3/8-24 UNF thread designation indicates a fine-pitch, inch-series thread. The fastener is fully threaded along its 3/4-inch overall length. This package contains 25 pieces. Typical installers include millwrights, mechanical technicians, and maintenance professionals working on assemblies that require low-profile fastening with controlled clamp load.

This screw is suited for use in close-tolerance assemblies where the head must sit flush with or below the workpiece surface. The fine-thread 3/8-24 specification makes it a common choice in precision machinery, tooling fixtures, and mechanical subassemblies. The black oxide finish provides mild corrosion resistance and reduces light reflection, which is useful in controlled environments. It is appropriate for both original assembly and field replacement work on equipment requiring ASME/ANSI B18.3 and ASTM F835 compliant fasteners.

Key Features

• 82-degree flat head for flush or countersunk seating
• 7/32-inch hex socket drive for use with standard Allen or hex key tooling
• 3/8-24 UNF fine-pitch thread for close-tolerance mechanical assemblies
• Fully threaded along entire 3/4-inch length
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835 standards
• Black oxide finish for mild corrosion resistance and low reflectivity

Compatibility

Designed as a standard inch-series flat socket cap screw conforming to ASME/ANSI B18.3 and ASTM F835, suitable for countersunk fastening applications in machinery, fixtures, and mechanical assemblies requiring a 3/8-24 UNF fine-thread fastener.

Installation Notes

Install using a calibrated 7/32-inch hex key or Allen driver to avoid rounding the socket. Countersink the mating material to the correct 82-degree included angle before seating the fastener. Do not exceed the rated drive torque for 3/8-inch alloy steel fasteners as specified by the equipment manufacturer or applicable engineering standards. Follow all applicable ASME and facility safety protocols when performing fastener installation or replacement.
