It features an 82-degree flat head with a Torx Plus T40 drive, providing higher torque transfer and reduced cam-out compared to standard hex drives. The fastener is fully threaded along its 3\/4-inch overall length with a 5\/16-18 UNC thread form. Constructed from alloy steel with a black oxide finish, it delivers solid mechanical strength and mild corrosion resistance. Machinists, millwrights, and assembly technicians install this screw in structural and mechanical assemblies where a low-profile head is required.\u003c\/p\u003e\n\u003cp\u003eThis screw suits industrial, manufacturing, and mechanical assembly applications where a countersunk fastener is needed to sit flush with or below a surface. The 5\/16-18 UNC thread is a common size across machine frames, tooling fixtures, enclosures, and equipment panels. The black oxide finish is appropriate for interior or low-moisture environments. It conforms to ASME\/ANSI B18.3 and ASTM F835 fastener standards, making it suitable for engineered assemblies with defined fastener specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head for flush or countersunk installation\u003c\/li\u003e\n  \u003cli\u003eTorx Plus T40 drive for high torque transfer and reduced cam-out\u003c\/li\u003e\n  \u003cli\u003eFully threaded 5\/16-18 UNC, 3\/4-inch overall length\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F835 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC flat socket cap screw for use in machine frames, tooling fixtures, enclosures, and mechanical assemblies requiring a countersunk fastener to ASME\/ANSI B18.3 and ASTM F835 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a T40 Torx Plus bit or driver. Verify the mating hole is properly countersunk to 82 degrees before installation to ensure full head seating.
