Value Collection 354-0306-01 Flat Socket Cap Screw 10-24

Product Description

The VALUE COLLECTION 354-0306-01 is a flat socket cap screw engineered for flush-mount fastening applications in metal assemblies and mechanical structures. It features a 10-24 UNC thread, an overall length of 3/8 inches, and a fully threaded shank. The 82-degree flat head seats flush with or below the mating surface when installed in a properly countersunk hole. Drive engagement is through a T25 Torx Plus socket, which reduces cam-out under high torque compared to hex drives. Constructed from alloy steel with a black oxide finish, the fastener offers moderate corrosion resistance and a low-reflectance appearance suited to close-tolerance assemblies.

This screw is used in light mechanical assemblies, jigs and fixtures, enclosures, and equipment panels where a flush surface profile is required. The 10-24 thread size and compact 3/8-inch length make it well suited for thin-stock applications. Machinists, millwrights, maintenance technicians, and equipment fabricators commonly install this fastener where standard hex socket flat heads are acceptable but a Torx Plus drive is preferred for torque transmission or tamper considerations. It is packaged individually with a minimum order quantity of 100 pieces.

Key Features

• 82-degree flat head countersink profile for flush or sub-flush installation
• T25 Torx Plus drive reduces cam-out and allows higher torque transfer than standard hex socket
• Fully threaded shank on a 3/8-inch overall length for maximum thread engagement in thin materials
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835 fastener standards
• Black oxide finish provides mild corrosion resistance and low-reflectance appearance
• UNC thread standard for compatibility with standard inch-series tapped holes

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a 10-24 UNC fully threaded flat socket cap screw with an 82-degree head angle and T25 Torx Plus drive in alloy steel.

Installation Notes

Installation requires a properly sized 82-degree countersink in the mating material before seating the fastener flush. Use a T25 Torx Plus bit driver or socket; do not substitute standard Torx bits, as Torx Plus flanks differ in geometry. Follow ASME B18.3 tightening practices for the thread size and material being fastened. Confirm the tapped hole meets 10-24 UNC thread form and depth requirements before assembly.
