Value Collection 721184PR Flat Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 721184PR is a flat socket cap screw designed for applications requiring a low-profile, flush-mount fastener. It features a 82-degree flat head driven by a 7/32-inch hex socket and is manufactured from alloy steel with a black oxide finish for corrosion resistance. The 3/8-16 UNC thread and 2-3/4-inch overall length make it suitable for medium-load structural and mechanical assemblies. The partially threaded shank allows for precise clamping force in bolted joint applications. Machinists, millwrights, maintenance technicians, and fabricators typically install this fastener in steel and ferrous assemblies across industrial and commercial settings.

This flat socket cap screw is used in applications where the fastener head must sit flush or countersunk within the mating surface, eliminating protrusions that could interfere with adjacent components or moving parts. Common install scenarios include machine frames, fixtures, jigs, enclosure panels, and general mechanical assemblies that specify 3/8-16 UNC thread fasteners per ASME/ANSI B18.3 or ASTM F835 standards. The black oxide finish provides mild corrosion protection suitable for indoor and low-moisture environments.

Key Features

• 82-degree flat head profile for flush or countersunk installation
• 7/32-inch hex socket drive for precise torque application with standard hex keys or drivers
• Partially threaded shank for controlled clamping force in bolted joints
• Alloy steel construction for high tensile strength in mechanical assemblies
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style or replacement fastener for mechanical assemblies, fixtures, and equipment requiring a 3/8-16 UNC partially threaded flat socket cap screw with 2-3/4-inch overall length per ASME/ANSI B18.3 specifications.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a calibrated torque wrench and the appropriate 7/32-inch hex key or socket driver. Ensure the mating hole is properly countersunk to 82 degrees before installation. De-energize and lock out any machinery before replacing fasteners in live equipment per applicable OSHA lockout/tagout procedures. Do not reuse fasteners that show signs of thread damage, galling, or deformation.
