Value Collection 721138PR Flat Socket Cap Screw 10-32

Product Description

The VALUE COLLECTION 721138PR is a flat socket cap screw engineered for precision fastening applications where a flush or countersunk finish is required. It features an 82-degree flat head with a 1/8 inch hex socket drive and is manufactured from alloy steel with a black oxide finish for improved corrosion resistance and reduced light reflection. The screw measures 2-1/2 inches in overall length with a 10-32 UNF thread and is partially threaded. Machinists, fabricators, and industrial maintenance technicians use this fastener in assemblies where a low-profile head is critical to fit and function.

This flat socket cap screw is suited for use in machine components, fixtures, tooling, and equipment frames where the fastener head must sit flush with or below the mating surface. The 10-32 UNF thread size is common in precision instrument work, light mechanical assemblies, and panel fabrication. The black oxide finish makes it a practical choice in environments where surface glare or mild surface protection is a consideration. Minimum order quantity is 100 pieces.

Key Features

• 82-degree flat head profile for flush countersunk installation
• 1/8 inch hex socket drive for standard Allen key or hex bit
• Alloy steel construction for high tensile strength
• Black oxide finish for mild corrosion resistance and reduced reflectivity
• Partially threaded shank — 10-32 UNF thread standard
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard inch-series flat socket cap screw for use in countersunk through-holes machined to accept an 82-degree flat head, compatible with any assembly calling for a 10-32 UNF partially threaded flat socket cap screw per ASME/ANSI B18.3.

Installation Notes

Installation is performed with a 1/8 inch hex key or matching hex bit driver. Countersink the mating hole to 82 degrees before installation to ensure proper head seating and flush fit. Apply appropriate thread-locking compound or torque per your assembly specification. Always verify thread engagement and hole depth before final torque.
