Value Collection 721088PR Flat Socket Cap Screw 8-32

Product Description

The VALUE COLLECTION 721088PR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a hex socket drive and is fully threaded along its 5/16-inch overall length. Manufactured from alloy steel with a black oxide finish, this screw offers good mechanical strength and moderate corrosion resistance in typical indoor or protected environments. The 8-32 UNC thread form meets ASME/ANSI B18.3 and ASTM F835 fastener standards. Machinists, maintenance technicians, and assembly professionals use this type of screw where a low-profile head and internal drive access are required.

This flat socket cap screw is suited for light to medium-duty mechanical assemblies, tooling fixtures, machine panels, and equipment enclosures where the screw head must sit flush with or below the surface of the mating material. The fully threaded shank maximizes thread engagement across the full length, which is particularly useful in thin-material applications. Sold individually, with a minimum order quantity of 100 pieces per order.

Key Features

• Flat head profile allows flush or countersunk installation in mating material
• Hex socket drive accepts a 3/32-inch hex key for installation in tight or recessed spaces
• Fully threaded along entire 5/16-inch length for maximum thread engagement
• Alloy steel construction provides solid mechanical strength for fastening applications
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in any application requiring an 8-32 UNC fully threaded flat socket cap screw with a 5/16-inch overall length and a countersunk seating surface.

Installation Notes

Installation requires a 3/32-inch hex key or hex socket bit. The mating material should be properly countersunk to the correct angle to seat the flat head flush. Ensure the tapped hole or nut meets 8-32 UNC thread specifications before driving the screw. Avoid overtightening, which can strip threads or crack countersunk material, particularly in softer substrates.
