Threaded to a 1-1\/4-7 UNC specification with a 6-inch length under head, this fastener is driven with a 7\/8-inch hex key. Constructed from 18-8 stainless steel with a bright, uncoated finish, it delivers solid corrosion resistance and mechanical strength across a wide range of environments. At 1.25 pounds, this is a full-size fastener suited for demanding installations requiring precise thread engagement and reliable clamping force.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in heavy equipment assembly, pump and compressor mounting, structural fabrication, and industrial maintenance applications. The 1-1\/4-7 UNC coarse thread is well suited for installations into steel, cast iron, and aluminum where quick engagement and strong pullout resistance are priorities. Typical installers include millwrights, pipefitters, machinists, and mechanical contractors working in commercial and industrial settings. The uncoated 18-8 stainless finish makes it appropriate for mildly corrosive environments including wet or outdoor-exposed installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-7 UNC coarse thread for strong clamping in heavy-load assemblies\u003c\/li\u003e\n  \u003cli\u003e6-inch length under head provides deep thread engagement in thick materials\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch hex drive accepts standard hex keys and socket tooling\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction for corrosion resistance in wet or exposed environments\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish maintains dimensional accuracy for precision-fit applications\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging for exact-quantity procurement on targeted repairs or builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1-1\/4-7 UNC hex socket cap screw for use in any application calling for this thread specification and length under head.

De-energize, depressurize, or lock out any equipment before fastener replacement or assembly work. Apply thread lubricant or anti-seize compound as required by the application to prevent galling in stainless-to-stainless connections.
