Value Collection 354-0620-01 Flat Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 354-0620-01 is a flat socket cap screw designed for applications requiring a low-profile, flush-mount fastener with high torque transfer. It features a Torx Plus T45 drive and an 82-degree flat head geometry, allowing the fastener to seat flush or slightly below the surface of the mating material. The screw is fully threaded with a 3/8-16 UNC thread form and measures 1-1/4 inches in overall length. Manufactured from alloy steel with a black oxide finish, it offers improved corrosion resistance and a clean, non-reflective appearance. Licensed mechanics, millwrights, machinists, and maintenance technicians are the typical installers.

This flat socket cap screw is suited for use in machine assemblies, tooling fixtures, mechanical enclosures, and structural fastening applications where a countersunk, flush fastener is required. The Torx Plus drive reduces cam-out under high torque, making it a practical choice for production environments and field service applications. The black oxide finish is appropriate for indoor and light-duty applications where moderate corrosion resistance is acceptable. The UNC thread form is compatible with standard inch-system tapped holes and nuts.

Key Features

• 82-degree flat head profile allows flush or sub-flush installation in countersunk holes
• Torx Plus T45 drive provides high torque transfer and reduced cam-out compared to hex socket drives
• Fully threaded 3/8-16 UNC shank for maximum thread engagement across the full length
• Alloy steel construction delivers high tensile strength for demanding fastening applications
• Black oxide finish provides light corrosion resistance and a non-reflective surface
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard inch-system flat socket cap screw compatible with any 3/8-16 UNC tapped hole or threaded insert requiring an 82-degree countersink and a Torx Plus T45 drive.

Installation Notes

Installation requires a calibrated T45 Torx Plus bit or driver rated for the torque demands of 3/8-16 alloy steel fasteners. Ensure the mating countersink is machined to an 82-degree included angle to achieve full head seating. Power down or de-energize any equipment before fastener service in electromechanical assemblies. Follow applicable industry and facility torque specifications for 3/8-16 alloy steel fasteners as defined in your engineering documentation.
