Value Collection 211052PR Flat Socket Cap Screw 8-32

Product Description

The VALUE COLLECTION 211052PR is an 8-32 x 5/8 inch flat socket cap screw designed for flush or countersunk fastening applications in metal assemblies and mechanical components. The 82-degree flat head seats flush with the work surface when driven into a properly countersunk hole, eliminating protrusion that could interfere with mating parts or moving components. The hex socket drive accepts a 3/32 inch hex key for precise torque application in tight or recessed spaces. Manufactured from alloy steel with a black oxide finish, this screw provides solid mechanical strength with moderate corrosion resistance for indoor and light-duty industrial environments. The thread is fully threaded at UNC 8-32, meeting ASME/ANSI B18.3 and ASTM F835 dimensional standards.

This fastener is suited for light mechanical assemblies, precision instrument housings, fixtures, and machine components where a flush head profile is required. The 8-32 UNC thread is a common size in general machine work, electronics enclosures, and tooling fixtures. Machinists, maintenance technicians, and mechanical assemblers regularly use this screw size when building or servicing equipment that requires a clean, snag-free surface. The black oxide finish blends visually with dark anodized or painted components and reduces light reflection in optical or electronic assemblies.

Key Features

• 82-degree flat head seats flush in standard countersunk holes for a snag-free surface
• Hex socket drive (3/32 inch) allows installation in recessed or tight clearance areas
• Fully threaded 8-32 UNC shank provides maximum thread engagement over the full length
• Alloy steel construction delivers reliable tensile and shear strength for mechanical fastening
• Black oxide finish offers mild corrosion resistance and low-reflectance appearance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards for dimensional and performance compliance

Compatibility

Designed as a standard UNC 8-32 flat socket cap screw for use in any tapped hole or threaded insert conforming to 8-32 UNC thread specifications with an 82-degree countersunk seat.

Installation Notes

Installation is performed by machinists, assemblers, or maintenance technicians using a 3/32 inch hex key or Allen driver. The mating hole must be countersunk to 82 degrees at the correct diameter to allow the flat head to seat fully flush. De-energize or lock out any equipment before servicing fastened assemblies per applicable safety procedures. Avoid overtightening in soft base materials such as aluminum or plastic to prevent stripping the tapped thread.
