Sized at 3\/8-24 UNF fully threaded with a 1-inch length under head, it accepts a 7\/32-inch hex socket drive. The alloy steel construction is finished in black oxide for corrosion resistance and reduced light reflection. Hardness is rated at 38 HRC, meeting ANSI\/ASME B18.3 and ASTM F835 standards. The 3A thread fit class ensures a precise, snug engagement. This fastener is installed by machinists, maintenance technicians, and mechanical contractors in industrial and commercial assemblies.\u003c\/p\u003e\n\u003cp\u003eThe 65038 is suited for mechanical assemblies, fixture builds, machine frames, and equipment panels where a flush or near-flush fastener profile is needed. The right-hand thread direction and UNF thread standard make it a common choice in precision equipment, tooling jigs, and structural hardware applications where controlled thread engagement is required. The black oxide finish also makes it a functional choice in applications where glare reduction is a practical concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButton head profile provides low-profile installation in tight clearance assemblies\u003c\/li\u003e\n  \u003cli\u003e7\/32-inch hex socket drive for standard Allen key or hex bit tooling\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated at 38 HRC hardness\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and low reflectivity\u003c\/li\u003e\n  \u003cli\u003eFully threaded 3\/8-24 UNF right-hand thread, class 3A fit\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-supply button socket cap screw for mechanical assemblies requiring a 3\/8-24 UNF fully threaded fastener with a 1-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician using the correct 7\/32-inch hex key or socket bit.
