Manufactured from alloy steel with a black oxide finish, this fastener delivers corrosion resistance and a hardness rating of 36-43 HRC. The hex socket drive accepts a 5\/16 inch drive tool, and the screw is fully threaded with a 3\/4 inch length under head. The unified national coarse (UNC) thread standard and 3A thread fit class ensure consistent engagement across compatible hardware. Licensed tradespeople and maintenance technicians install these fasteners across a wide range of mechanical assemblies.\u003c\/p\u003e\u003cp\u003eThis button socket cap screw is suited for applications where a standard hex head would interfere with surrounding components or clearance is limited. The low-profile button head reduces snag points and distributes load across the bearing surface. Typical uses include machine frames, equipment panels, brackets, and structural assemblies in industrial, commercial, and trade-service environments. Each package contains 25 screws, making it appropriate for both single repairs and small batch production work. The black oxide finish is commonly used where mild corrosion resistance is acceptable and aesthetics are a secondary consideration.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlloy steel construction with 36-43 HRC hardness for high-strength fastening\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance\u003c\/li\u003e\n\u003cli\u003e1\/2-13 UNC thread with 3A fit class for consistent thread engagement\u003c\/li\u003e\n\u003cli\u003e5\/16 inch hex socket drive for standard tooling compatibility\u003c\/li\u003e\n\u003cli\u003eLow-profile button head suitable for clearance-restricted installations\u003c\/li\u003e\n\u003cli\u003eFully threaded shank along the 3\/4 inch length under head\u003c\/li\u003e\n\u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-service fastener compatible with any 1\/2-13 UNC threaded hole requiring a button socket cap screw per ANSI\/ASME B18.3 and ASTM F835 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 5\/16 inch hex socket key or driver.
