It features a 1-1\/4-7 UNC thread size and measures 2.75 inches in length under the head. The screw is machined from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and reduces light reflection on exposed hardware. A 7\/8-inch hex drive socket is required for installation. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it a code-compliant choice for demanding fastening applications.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for heavy-duty mechanical assemblies, machinery, and industrial equipment where high clamping force and precision threading are required. The 1-1\/4-7 UNC coarse thread pattern offers reliable engagement in both tapped holes and threaded inserts. It is a common choice for maintenance technicians, machinists, and millwrights working on presses, frames, gearboxes, and similar equipment requiring large-diameter fasteners.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4-7 UNC thread size for coarse-thread engagement in heavy-duty assemblies\u003c\/li\u003e\n\u003cli\u003e2.75 inches length under head — fully threaded for maximum thread engagement\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 moderate corrosion resistance and surface hardness\u003c\/li\u003e\n\u003cli\u003e7\/8-inch hex socket drive for use with standard impact or torque drive tools\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC coarse-thread hex socket cap screw for use in tapped holes or threaded assemblies requiring a 1-1\/4-7 thread specification per ASME\/ANSI B18.3.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 7\/8-inch hex socket driver or Allen key of adequate length and strength for the fastener size. De-energize and lock out all equipment before servicing any mechanical assembly. Apply thread lubricant or anti-seize compound as appropriate for the mating material to achieve accurate torque loading.
