Value Collection 354-0412-01 Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 354-0412-01 is a 1/4-20 x 3/4 inch flat socket cap screw designed for flush or countersunk fastening applications in metal, wood, and composite assemblies. It features a Torx Plus drive with a T30 bit size and an 82-degree flat head profile. The screw is fully threaded along its 3/4-inch overall length and manufactured from alloy steel with a black oxide finish, offering moderate corrosion resistance and a low-reflectance appearance. Machinists, millwrights, and maintenance technicians commonly use this fastener where a recessed head is required and a hex socket drive is not preferred.

This fastener suits general industrial, mechanical, and structural assembly work where an 82-degree countersunk seat is present. The Torx Plus drive reduces cam-out risk compared to standard hex or Phillips drives, making it well suited for production environments and repetitive installation tasks. The UNC thread form is compatible with standard 1/4-20 tapped holes and threaded inserts common in machine frames, fixtures, enclosures, and equipment panels.

Key Features

• 1/4-20 UNC thread, fully threaded over 3/4 inch overall length
• 82-degree flat head profile for flush countersunk installations
• Torx Plus T30 drive reduces cam-out during installation and removal
• Alloy steel construction for higher tensile strength than standard steel fasteners
• Black oxide finish provides mild corrosion resistance and low-glare appearance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in any application with a standard 1/4-20 UNC tapped hole or threaded insert requiring an 82-degree countersunk flat head seat and a Torx Plus T30 drive tool.

Installation Notes

Install using a T30 Torx Plus bit; standard Torx bits may fit but can reduce drive engagement and increase wear. Ensure the mating countersink is machined to an 82-degree included angle to achieve full head seating. De-energize or lock out any equipment before fastener removal or replacement per applicable safety procedures. Follow ASME B18.3 guidelines for proper hole preparation and thread engagement depth.
