It features a 1-1\/4-7 UNC thread and a 7\/8-inch hex drive socket, allowing torque to be applied with a standard hex key or Allen wrench. The screw is fully threaded with a 3-inch length under head and is manufactured from alloy steel with a black oxide finish for corrosion resistance. Installation is performed by mechanical contractors, maintenance technicians, and millwrights working on heavy equipment, fixtures, or machinery frames.\u003c\/p\u003e\n\u003cp\u003eThis cap screw suits applications where a flush or recessed fastener head is required and high clamping force is necessary. The coarse 1-1\/4-7 UNC thread pattern provides reliable engagement in standard tapped holes and is compatible with common inch-series tooling. It is used across general manufacturing, equipment assembly, and maintenance repair operations where alloy steel fasteners are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-7 UNC coarse thread for strong engagement in inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head provides substantial grip length for thick joint stacks\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch hex socket drive for high-torque installation with standard hex keys\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank maximizes thread engagement across the full grip length\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating reduces surface corrosion and provides a low-reflectance finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1-1\/4-7 UNC tapped holes per ASME\/ANSI B18.3 specifications.
