Value Collection 721017PR Flat Socket Cap Screw 12-24 1 in

Product Description

The VALUE COLLECTION 721017PR is a flat socket cap screw designed for precision fastening applications where a flush or countersunk head profile is required. Sized at 12-24 UNC with a 1-inch overall length, this screw is fully threaded and features an 82-degree flat head with a hex socket drive. Manufactured from alloy steel with a black oxide finish, it provides moderate corrosion resistance and a clean appearance suitable for machine assemblies, fixtures, and tooling. Machinists, maintenance technicians, and general fabricators are the typical installers of this fastener type.

This screw is suited for use in metalworking, industrial equipment assembly, and mechanical fixture applications where a countersunk fastener is needed to maintain a low-profile or flush surface. The 12-24 UNC thread is a coarse unified thread standard widely used in machine screws across general-purpose inch-series applications. The black oxide finish helps reduce light reflection and provides light surface protection in controlled environments. This item is sold individually but carries a minimum order quantity of 100 pieces.

Key Features

• 82-degree flat head seats flush in standard countersunk holes for a low-profile installation
• Hex socket drive allows torque application in confined or recessed areas
• Fully threaded 12-24 UNC alloy steel construction for consistent thread engagement along the full length
• Black oxide finish provides light corrosion resistance and reduced glare
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards
• Inch measurement system with 1-inch overall length for consistent fit in standard inch-series assemblies

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any application requiring a 12-24 UNC countersunk fastener conforming to ASME/ANSI B18.3 and ASTM F835 standards.

Installation Notes

Installation requires a properly sized hex key or socket driver rated for the hex socket drive. The mating material should be drilled and countersunk to the correct 82-degree angle before fastener installation to ensure full head seating. Always use a calibrated torque tool appropriate for the alloy steel material and thread size to avoid stripping. Power down or de-energize any equipment before performing fastener work on live assemblies.
