Value Collection 354-5812-01 Flat Socket Cap Screw 8-32

Product Description

The VALUE COLLECTION 354-5812-01 is an 8-32 x 3/4 inch flat socket cap screw designed for precision fastening applications that require a flush or countersunk finish. Manufactured from alloy steel with a black oxide coating, it delivers solid corrosion resistance in moderate environments while reducing light reflection in finished assemblies. The Torx Plus T20 drive interface provides a more positive engagement than standard hex or Phillips drives, reducing cam-out risk under torque. The 82-degree flat head geometry is fully threaded along its 3/4 inch overall length, conforming to ASME/ANSI B18.3 and ASTM F835 standards. Mechanical contractors, millwrights, OEM assemblers, and maintenance technicians use this fastener where a low-profile head is required alongside reliable drive engagement.

This screw is suited for light-to-medium load applications in industrial equipment, machine assemblies, enclosures, and structural panels where a countersunk mounting point is necessary. The UNC thread standard and inch-system dimensions make it compatible with standard tapped holes in steel, aluminum, and thermoplastic components. The black oxide finish is appropriate for interior or protected outdoor installations where moderate oxidation resistance is acceptable.

Key Features

• 82-degree flat head for flush, countersunk installations
• Torx Plus T20 drive reduces cam-out and allows higher drive torque than standard hex
• Fully threaded along entire 3/4 inch overall length for maximum thread engagement
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish offers moderate corrosion resistance and low surface reflectivity
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNC inch-series flat socket cap screw for use in any application requiring an 8-32 tapped hole with an 82-degree countersink profile.

Installation Notes

Installation requires a Torx Plus T20 driver or bit; standard Torx T20 bits may fit but can reduce engagement quality over time. Ensure the mating countersink is machined to an 82-degree included angle before installation. Always torque to the assembly specification for the base material and fastener grade — alloy steel flat socket cap screws are commonly installed with a calibrated torque wrench or driver to avoid stripping the countersink. Follow applicable fastener and machinery standards for joint design and preload.
