Value Collection 354-0308-01 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 354-0308-01 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a T25 Torx Plus drive, an 82-degree flat head, and a fully threaded shank in a 10-24 UNC thread form at 0.5 inches overall length. The alloy steel construction with a black oxide finish provides moderate corrosion resistance and reduced light reflection. This screw is installed by machinists, millwrights, electricians, and mechanical contractors working on panels, assemblies, and equipment enclosures where a low-profile fastener is required.

This screw is suited for light mechanical assemblies, electrical enclosures, equipment panels, and precision fixtures where a countersunk profile is needed to keep mating surfaces flush. The 10-24 UNC thread is a common fastener size found across a wide range of industrial, commercial, and light-duty mechanical applications. The fully threaded shank ensures maximum thread engagement across the entire grip length, which is particularly useful when threading into thin materials or threaded inserts.

Key Features

• 82-degree flat head provides a flush countersunk profile in standard countersunk holes
• T25 Torx Plus drive resists cam-out during installation and removal
• Fully threaded shank for maximum thread engagement at 0.5 inches overall length
• Alloy steel construction offers high tensile strength relative to standard carbon steel fasteners
• Black oxide finish reduces surface reflectivity and provides light corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 10-24 UNC flat socket cap screw compatible with countersunk hole patterns conforming to ASME/ANSI B18.3 specifications in inch-system assemblies.

Installation Notes

Installation requires a T25 Torx Plus driver or bit; do not substitute a standard Torx T25 bit if torque precision is required, as the Torx Plus profile differs slightly. Countersink the receiving hole to 82 degrees to achieve a fully flush head seating. Apply appropriate thread torque per ASME B18.3 guidelines for 10-24 alloy steel fasteners; do not use an impact driver without a torque-limiting adapter on precision assemblies. Verify thread engagement depth in the mating material before final assembly.
