This fastener features a 1-1\/4-7 UNC thread size, an 8-inch length under head, and a 7\/8-inch hex drive. Manufactured from alloy steel and finished with a black oxide coating, it provides solid corrosion resistance in moderate environments. Partially threaded shank design allows for proper clamping force in bolted joint applications. Installation requires a 7\/8-inch hex key or socket driver. This screw conforms to ASME\/ANSI B18.3 and ASTM A574 standards.\u003c\/p\u003e\n\u003cp\u003eThis hex socket cap screw is suited for heavy industrial machinery, structural steel assemblies, tooling fixtures, and OEM equipment builds where high tensile strength and reliable clamping are required. The coarse 1-1\/4-7 UNC thread pitch makes it a practical choice for use in steel and cast iron applications where quick assembly and disassembly are needed. Machinists, millwrights, and maintenance technicians working in manufacturing, fabrication, and heavy equipment service are the primary installers of this fastener.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-7 UNC coarse thread for use in steel and cast iron tapped holes\u003c\/li\u003e\n  \u003cli\u003e8-inch length under head with partial threading for proper joint clamping\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch hex drive accommodates standard hex keys and socket drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength fastener requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides moderate corrosion and wear 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 an OEM-style replacement or standard-supply hex socket cap screw for industrial machinery and structural assemblies requiring a 1-1\/4-7 UNC thread form and ASME\/ANSI B18.3 compliance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist, millwright, or maintenance technician using a properly sized 7\/8-inch hex key or drive tool. Ensure the mating tapped hole is clean, undamaged, and matches the 1-1\/4-7 UNC thread form before installation. De-energize and lock out all equipment per applicable OSHA lockout\/tagout procedures before servicing any bolted assembly.
