Value Collection 354-0424-01 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 354-0424-01 is a flat socket cap screw designed for flush or countersunk fastening applications in metal assemblies. It features a 1/4-20 UNC thread at 1-1/2 inches overall length and is driven with a T30 Torx Plus bit, offering higher torque transfer and better bit engagement than standard hex socket drives. The 82-degree flat head seats flush with the workpiece surface, making it well suited for applications where a low-profile or smooth finish is required. This fastener is fully threaded and manufactured from alloy steel with a black oxide finish for moderate corrosion resistance.

This screw is used in mechanical assemblies, fixtures, and fabricated components where a countersunk, flush-mount fastening point is needed. The Torx Plus drive reduces cam-out risk during installation, which is especially useful in production environments or repetitive assembly work. It conforms to ASME/ANSI B18.3 and ASTM F835 standards. Machinists, millwrights, and general maintenance trades commonly install this fastener in both light industrial and commercial settings.

Key Features

• 82-degree flat head profile for flush countersunk installation
• T30 Torx Plus drive for high torque transfer and reduced cam-out
• Fully threaded 1/4-20 UNC thread form along the full 1-1/2 inch length
• Alloy steel construction for strength in demanding mechanical assemblies
• Black oxide finish provides mild corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 1/4-20 UNC flat socket cap screw for use in any countersunk hole prepared to accept an 82-degree flat head profile per ASME/ANSI B18.3 specifications.

Installation Notes

Install using a T30 Torx Plus bit rated for the applied torque. Countersink the mating hole to 82 degrees before installation to ensure proper head seating. Power down or de-energize any equipment before accessing fastened assemblies on live machinery. Follow applicable industry standards and equipment manufacturer guidelines for torque requirements specific to the assembly.
