With a thread size of 8-32 UNC and a 1-3\/4 inch length under head, this partially threaded fastener is built from alloy steel and finished with a black oxide coating for added corrosion resistance. The 9\/64 inch hex drive accepts a standard Allen key or hex bit driver. This screw meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for applications that require a reliable, spec-compliant fastener. It is installed by machinists, maintenance technicians, and assembly professionals across manufacturing and industrial settings.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in a wide range of mechanical and industrial applications including equipment assembly, machine frames, jigs, fixtures, and component mounting. The black oxide finish reduces light reflection and provides mild corrosion resistance in dry or lightly humid environments. The partial threading allows the unthreaded shank to act as a locating feature or bear shear loads, which is common in precision assemblies and close-tolerance machined components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread size: 8-32 UNC for standard unified coarse thread engagement\u003c\/li\u003e\n  \u003cli\u003e1-3\/4 inch length under head with partial threading\u003c\/li\u003e\n  \u003cli\u003e9\/64 inch hex socket drive — compatible with standard Allen keys and hex bit sets\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 for high tensile strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n  \u003cli\u003eCompliant with ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-fit fastener for any application requiring an 8-32 UNC hex socket cap screw with a 1-3\/4 inch length under head and a 9\/64 inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a correctly sized 9\/64 inch hex key or hex bit to avoid socket damage or cam-out.
