Manufactured from alloy steel with a black oxide finish, it delivers high tensile strength and moderate corrosion resistance in a compact head profile. The hex socket drive accepts a 7\/32-inch hex key for precise torque application in confined spaces where a standard hex head wrench cannot reach. With a hardness rating of 36-43 HRC and a thread fit class of 3A, this fastener meets tight tolerance requirements for demanding industrial and equipment assembly work.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in machine assembly, tooling fixtures, enclosures, and general fabrication where a button head profile is required to keep fastener heads flush or below the work surface. The fully threaded 1-1\/4-inch shank under the head provides maximum thread engagement throughout the full length of the grip. It is commonly installed by machinists, millwrights, and maintenance technicians in both light and heavy manufacturing environments. The UNC thread form is the standard for inch-series fastener applications across North American industry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButton head profile keeps fasteners low-profile in assemblies where clearance is limited\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high hardness of 36-43 HRC for demanding load applications\u003c\/li\u003e\n  \u003cli\u003e7\/32-inch hex socket drive for use with standard Allen or hex key tooling\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank maximizes thread engagement along the entire 1-1\/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\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard fastener for inch-series UNC threaded applications requiring a 3\/8-16 button socket cap screw in alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 7\/32-inch hex key or Allen driver. Power down and de-energize any equipment before accessing fastened assemblies on live machinery. Ensure mating threads are clean and free of debris before installation.
