Value Collection 721284BR Flat Socket Cap Screw 3/4-10

Product Description

The VALUE COLLECTION 721284BR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. Manufactured from alloy steel with a black oxide finish, this screw provides moderate corrosion resistance and reduced light glare on the fastener head. The hex socket drive accepts a 1/2-inch hex key for installation. Threading is 3/4-10 UNC, fully threaded along its 1-inch overall length. Licensed tradespeople and fabricators working with structural assemblies, machinery, or mechanical fixtures will encounter this fastener type regularly.

This flat socket cap screw is suited for use in machine assemblies, fixtures, jigs, and structural connections where the fastener head must sit flush with or below the mating surface. The countersunk flat head profile allows the fastener to seat into a properly prepared countersunk hole, keeping surfaces clear of protrusion. It is commonly specified in metalworking, industrial equipment, and mechanical fabrication environments. Each order unit is a single screw; the minimum order quantity is 10 pieces.

Key Features

• Flat countersunk head seats flush with or below the surface in a prepared countersunk hole
• 3/4-10 UNC thread form, fully threaded over the 1-inch overall length
• 1/2-inch hex socket drive for standard hex key or socket bit installation
• Alloy steel construction provides high tensile strength for load-bearing applications
• Black oxide finish reduces surface reflectivity and offers mild corrosion protection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style or aftermarket replacement flat socket cap screw for machinery, fixtures, and structural assemblies requiring a 3/4-10 UNC fully threaded countersunk fastener.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical contractors. The mating hole must be properly countersunk to the correct angle to allow the flat head to seat flush. Power down and de-energize any equipment before fastener replacement on live machinery. Use a correctly sized 1/2-inch hex key or driver to avoid rounding the socket drive.
