Value Collection 354-0512-01 Flat Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 354-0512-01 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head with a Torx Plus T40 drive, providing higher torque transfer and reduced cam-out compared to standard hex drives. The fastener is fully threaded along its 3/4-inch overall length with a 5/16-18 UNC thread form. Constructed from alloy steel with a black oxide finish, it delivers solid mechanical strength and mild corrosion resistance. Machinists, millwrights, and assembly technicians install this screw in structural and mechanical assemblies where a low-profile head is required.

This screw suits industrial, manufacturing, and mechanical assembly applications where a countersunk fastener is needed to sit flush with or below a surface. The 5/16-18 UNC thread is a common size across machine frames, tooling fixtures, enclosures, and equipment panels. The black oxide finish is appropriate for interior or low-moisture environments. It conforms to ASME/ANSI B18.3 and ASTM F835 fastener standards, making it suitable for engineered assemblies with defined fastener specifications.

Key Features

• 82-degree flat head for flush or countersunk installation
• Torx Plus T40 drive for high torque transfer and reduced cam-out
• Fully threaded 5/16-18 UNC, 3/4-inch overall length
• Alloy steel construction for high tensile strength
• Black oxide finish provides mild corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F835 standards

Compatibility

Designed as a standard 5/16-18 UNC flat socket cap screw for use in machine frames, tooling fixtures, enclosures, and mechanical assemblies requiring a countersunk fastener to ASME/ANSI B18.3 and ASTM F835 specifications.

Installation Notes

Installation requires a T40 Torx Plus bit or driver. Verify the mating hole is properly countersunk to 82 degrees before installation to ensure full head seating. Follow applicable engineering or assembly specifications for torque requirements, as no specific torque value is supplied with this fastener. Black oxide finish is not rated for outdoor or high-moisture environments without additional corrosion protection.
