Value Collection 721545BR Flat Socket Cap Screw 1-8x7 in

Product Description

The VALUE COLLECTION 721545BR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head driven by a 5/8-inch hex socket, making it compatible with standard Allen-type drive tools. The screw measures 1-8 x 7 inches overall and is partially threaded along its length. Manufactured from alloy steel with a black oxide finish, it delivers solid mechanical strength and moderate corrosion resistance in a range of industrial and structural installations. This fastener conforms to ASME/ANSI B18.3 and ASTM F835 standards.

This flat socket cap screw is suited for use in mechanical assemblies, machine components, and structural connections where a low-profile countersunk head is required. The UNC thread standard makes it compatible with standard inch-system tapped holes. Partial threading is typical for grip-critical joints where the unthreaded shank must span a clearance hole. It is commonly installed by machinists, millwrights, maintenance technicians, and mechanical contractors working in both light industrial and heavy equipment environments.

Key Features

• 82-degree flat head sits flush or below surface in countersunk applications
• 5/8-inch hex socket drive for standard Allen wrench or hex bit installation
• Alloy steel construction provides high tensile strength for demanding fastening applications
• Black oxide finish offers mild corrosion resistance and reduced light reflection
• Partial threading supports shank-bearing load in clearance-hole assemblies
• Conforms to ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or direct-install fastener for standard inch-system UNC tapped holes requiring a 1-8 thread pitch and a countersunk flat socket head profile.

Installation Notes

This fastener is installed by machinists and mechanical technicians using a 5/8-inch hex key or hex socket bit. Ensure the mating hole is properly countersunk to 82 degrees before installation to achieve full head seating. Always confirm thread engagement depth meets applicable design requirements before torquing. Inspect the drive recess for debris before driving to avoid stripping the socket.
