Value Collection 211077P Flat Socket Cap Screw 10-32

Product Description

The VALUE COLLECTION 211077P is a flat socket cap screw designed for flush or countersunk fastening applications in mechanical assemblies. The 82-degree flat head seats fully into a countersunk hole, eliminating protrusion above the mating surface. Driven by a 1/8-inch hex socket, this screw is manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and reduces light reflection. At a thread size of 10-32 UNF and a length of 1/2 inch, it is fully threaded along its entire shank. This fastener meets ASME/ANSI B18.3 and ASTM F835 standards, making it appropriate for applications requiring dimensional and strength compliance.

This screw is suited for use in machine frames, jigs, fixtures, enclosures, and precision assemblies where a smooth, flush surface is required after fastening. The 10-32 UNF thread is a fine-pitch unified thread commonly found in instrumentation, electronics enclosures, and light industrial equipment. It is typically installed by machinists, maintenance technicians, and assembly personnel working on metal fabrication and mechanical assembly tasks.

Key Features

• 82-degree flat head for fully countersunk, flush-surface installation
• 1/8-inch hex socket drive for precise torque application with standard Allen keys or hex drivers
• 10-32 UNF fully threaded shank provides maximum thread engagement at 1/2-inch length
• Alloy steel construction delivers higher tensile strength compared to standard carbon steel fasteners
• Black oxide finish reduces surface reflectivity and offers light corrosion protection in dry environments
• Meets ASME/ANSI B18.3 and ASTM F835 dimensional and mechanical standards

Compatibility

Designed for use in any threaded 10-32 UNF countersunk hole requiring an 82-degree flat socket cap screw per ASME/ANSI B18.3 specification. Suitable for metal assemblies, enclosures, and fixtures that require a flush fastening surface.

Installation Notes

Installation requires a 1/8-inch hex key or hex socket driver; use of the correct driver size prevents cam-out and rounding of the socket recess. Countersink the mating material to 82 degrees at the appropriate diameter for a 10-32 screw before installation. Apply consistent torque appropriate to the alloy steel grade and the mating material to avoid thread stripping, particularly in softer base materials. Black oxide finish is not a heavy-duty corrosion barrier; avoid prolonged exposure to moisture or corrosive environments without additional protection such as a compatible oil or sealant.
