Value Collection 354-2408-01 Flat Socket Cap Screw 1/4-28

Product Description

The VALUE COLLECTION 354-2408-01 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features a Torx Plus drive with a T30 bit size and an 82-degree flat head geometry. The fastener is fully threaded along its 0.5-inch overall length, with a 1/4-28 UNF thread specification. Constructed from alloy steel with a black oxide finish, it provides solid mechanical strength and moderate corrosion resistance in controlled environments. This screw is installed by machinists, millwrights, equipment assemblers, and maintenance technicians working with metal assemblies that demand a low-profile head.

This fastener is suited for use in precision mechanical assemblies, tooling fixtures, machine components, and industrial equipment where a countersunk head is required to sit flush with or below the mating surface. The 1/4-28 UNF thread designation indicates a fine-pitch thread, which is common in applications requiring precise torque control or resistance to vibration loosening. The black oxide finish is appropriate for indoor or low-moisture environments and reduces light reflection on exposed surfaces. Sold individually with a minimum order quantity of 100 pieces.

Key Features

• Torx Plus drive, T30 size, reduces cam-out during installation
• 82-degree flat head seats flush in standard countersunk holes
• Fully threaded along entire 0.5-inch length for maximum thread engagement
• 1/4-28 UNF fine-pitch thread for vibration-resistant fastening
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835 standards
• Black oxide finish provides mild corrosion resistance and low-glare appearance

Compatibility

Designed as an OEM-style replacement or standard fastener for mechanical assemblies requiring a 1/4-28 UNF fully threaded flat socket cap screw with an 82-degree countersink angle and T30 Torx Plus drive.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a T30 Torx Plus driver or bit. Ensure the mating countersunk hole is machined to the correct 82-degree included angle before installation. Follow applicable torque specifications for 1/4-28 alloy steel fasteners as defined by your assembly engineering documentation. Power down and de-energize any machinery before performing fastener service on live equipment.
