It features a 1-1\/4-12 UNF thread — a fine-pitch unified thread that provides increased clamping force and vibration resistance compared to coarse-thread alternatives. The screw measures 3 inches under the head, is fully threaded, and accepts a 7\/8-inch hex drive. Constructed from alloy steel with a black oxide coating, it delivers solid corrosion resistance for general industrial use. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards. Machinists, millwrights, and maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for high-load bolted connections where a recessed socket drive is preferred over an external hex. The fine 12-pitch UNF thread is commonly used in applications requiring precise torque control or where the fastener threads into thin-walled or tapped steel components. Typical use cases include fixture mounting, machine bases, hydraulic component mounting, and structural mechanical assemblies in both shop and field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-12 UNF fine-pitch thread for increased clamping load and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the 3-inch under-head length\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch internal hex socket drive for high-torque installation\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides moderate corrosion and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw for use in any application requiring a 1-1\/4-12 UNF fully threaded fastener with a 7\/8-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated torque wrench with a 7\/8-inch hex bit to achieve proper clamping force without overstressing the fastener. Ensure mating threads are clean and free of debris before installation. Power down or de-energize any equipment before accessing fastened assemblies on live machinery.
