Value Collection 721575BR Flat Socket Cap Screw 3/4-10 X 7 in

Product Description

The VALUE COLLECTION 721575BR is a flat socket cap screw designed for flush or countersunk fastening applications in industrial and mechanical assemblies. Sized at 3/4-10 thread with an overall length of 7 inches, this fastener is partially threaded and features an 82-degree flat head profile. Drive interface is a 1/2-inch hex socket. Constructed from alloy steel with a black oxide finish, it provides corrosion resistance and reduced light reflection, making it suitable for tooling, fixtures, and structural mechanical work. Installation is performed using a standard hex key or socket driver. This fastener conforms to ASME/ANSI B18.3 and ASTM F835 standards.

This flat socket cap screw is used in applications where a low-profile, flush-mount fastener is required and fastener head protrusion is not acceptable. Common in machine tool frames, jigs, structural steel assemblies, and equipment housings where UNC thread engagement and partial threading are appropriate. The black oxide alloy steel construction suits indoor and light industrial environments where moderate corrosion resistance is needed. It is typically installed by machinists, millwrights, and mechanical contractors.

Key Features

• 82-degree flat head seats flush in standard countersunk holes, eliminating head protrusion
• 1/2-inch hex socket drive for high torque application with standard hex tooling
• Partially threaded shank for controlled clamp load and alignment in through-bolted assemblies
• Alloy steel construction provides high tensile strength for demanding fastening applications
• Black oxide finish adds mild corrosion resistance and reduces reflectivity
• Conforms to ASME/ANSI B18.3 and ASTM F835 dimensional and material standards

Compatibility

Designed as an OEM-style replacement or standard-service fastener for applications requiring a 3/4-10 UNC flat socket cap screw per ASME/ANSI B18.3 and ASTM F835 specifications.

Installation Notes

Install using a calibrated 1/2-inch hex key or hex socket driver rated for the fastener size. Ensure the receiving hole is properly countersunk to 82 degrees before installation to achieve full head seating. De-energize or lock out any equipment before fastener service on live machinery. Follow applicable torque specifications from engineering drawings or the relevant ASME standard for the material and application.
