Value Collection 721206PR Flat Socket Cap Screw 3/8-16 X 5 in

Product Description

The VALUE COLLECTION 721206PR is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. With a 3/8-16 UNC thread and an overall length of 5 inches, this screw is partially threaded and driven by a 7/32-inch hex socket. It is manufactured from alloy steel with a black oxide finish, which provides moderate corrosion resistance and reduces light reflection in finished assemblies. This fastener meets ASME/ANSI B18.3 and ASTM F835 standards, making it suitable for precision mechanical assemblies, machinery, and structural applications where a recessed head is required. Installation is typically performed by machinists, millwrights, or maintenance technicians.

This flat socket cap screw is used in industrial and mechanical assembly applications where a flush seating surface is necessary. The countersunk flat head sits below or flush with the mating surface, making it a common choice for machine frames, fixtures, jigs, tooling plates, and equipment panels. The partial threading suits applications where the unthreaded shank provides a consistent bearing surface in clearance holes.

Key Features

• Flat countersunk head for flush or below-surface installation
• 7/32-inch hex socket drive for precise torque application
• 3/8-16 UNC thread, partially threaded over a 5-inch overall length
• Alloy steel construction for high tensile strength
• Black oxide finish for mild corrosion resistance and reduced reflectivity
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in 3/8-16 UNC tapped holes in industrial machinery, fixtures, and mechanical assemblies requiring a flat countersunk socket cap screw per ASME/ANSI B18.3.

Installation Notes

Installation is performed with a 7/32-inch hex key or socket bit. Ensure the mating hole is countersunk to the correct included angle to achieve full flat-head seating before applying final torque. De-energize or lock out any equipment before fastener service in accordance with applicable OSHA lockout/tagout procedures. Do not reuse fasteners that show signs of thread damage, galling, or deformation.
