Value Collection 354-2416-01 Flat Socket Cap Screw 1/4-28

Product Description

The VALUE COLLECTION 354-2416-01 is a 1/4-28 UNF flat socket cap screw designed for precision fastening applications requiring a flush or countersunk seating profile. Made from alloy steel with a black oxide finish, it delivers solid corrosion resistance in indoor and light industrial environments. The 82-degree flat head seats cleanly into standard countersunk holes, and the Torx Plus T30 drive reduces cam-out during installation. At 1 inch overall length and fully threaded, this fastener is suited for through-hole and blind-hole assemblies where consistent clamping load matters. It meets ASME/ANSI B18.3 and ASTM F835 standards.

This screw is used across mechanical assemblies, equipment enclosures, machine components, and structural panels where a low-profile flush head is required. The UNF thread pitch suits applications demanding finer thread engagement and higher tensile resistance than coarse-thread equivalents. Minimum order quantity is 100 pieces, making this fastener appropriate for production runs, MRO stocking, or bulk field use by millwrights, mechanical contractors, and equipment assemblers.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• Torx Plus T30 drive reduces cam-out and fastener damage during installation
• Fully threaded 1/4-28 UNF shank for maximum thread engagement
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835
• Black oxide finish provides mild corrosion and abrasion resistance
• 1 inch overall length, suitable for through-hole and blind-hole configurations

Compatibility

Designed as a standard 1/4-28 UNF flat socket cap screw compatible with countersunk hole patterns conforming to ASME/ANSI B18.3 specifications in inch-system assemblies.

Installation Notes

Installation is performed with a Torx Plus T30 driver or bit. Ensure the mating countersink angle matches 82 degrees to achieve proper head seating and avoid stress concentration at the bore edge. Follow applicable torque specifications from ASME or equipment manufacturer documentation for 1/4-28 alloy steel fasteners. Do not substitute a standard Torx bit for the Torx Plus drive interface, as this can damage the drive recess.
