Value Collection 36839 Flat Socket Cap Screw 3/8-16 X 2-1/4 in 25pk

Product Description

The VALUE COLLECTION 36839 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. The 82-degree flat head seats flush with or below the surface of the mating material, eliminating protrusion that would interfere with adjacent components. Driven by a 7/32-inch hex socket, it delivers high torque transfer in a compact head footprint. Manufactured from alloy steel with a black oxide finish, the 36839 offers solid mechanical strength and moderate corrosion resistance in controlled environments. Each screw is partially threaded and conforms to ASME/ANSI B18.3 and ASTM F835 standards. Sold in a package quantity of 25.

This screw is suited for general mechanical assemblies, machine components, fixtures, and tooling where a flush fastener is required. The 3/8-16 UNC thread pitch and 2-1/4-inch overall length make it appropriate for medium-duty structural connections in steel or aluminum assemblies. Typical installers include machinists, millwrights, maintenance technicians, and mechanical contractors working on equipment fabrication or repair. The black oxide finish blends well in finished or semi-finished assemblies where appearance and low reflectivity matter.

Key Features

• 82-degree flat head for flush or countersunk seating
• 7/32-inch hex socket drive for high torque transfer
• Alloy steel construction for mechanical strength
• Black oxide finish for moderate corrosion resistance and low reflectivity
• Partially threaded shank — 3/8-16 UNC thread standard
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard fastener for assemblies requiring a 3/8-16 UNC flat socket cap screw with an 82-degree head angle and 2-1/4-inch overall length.

Installation Notes

Installation requires a 7/32-inch hex key or socket driver. Ensure the mating hole is countersunk to an 82-degree included angle for proper head seating. Power down or de-energize any equipment before fastener service. Follow applicable mechanical and structural codes for fastener torque and joint design based on your specific application.
