Manufactured from Grade 12L14 steel with a black oxide finish, this nut features a 7\/8-9 thread size and an integrated flange that distributes clamping load across a wider surface area, reducing the need for a separate washer. The flange diameter measures 1-3\/4 inches, overall height is 1-1\/8 inches, flange height is 1\/4 inch, and the width across flats measures 1-7\/16 inches. The part weighs 0.44 pounds. It meets TCMAI fastener standards and is sold individually.\u003c\/p\u003e\n\u003cp\u003eThe GIBRALTAR 41608G suits structural, equipment-mounting, and mechanical assembly applications where a standard hex nut would require a backing washer. Common installation scenarios include HVAC equipment frames, pump and motor mounts, piping supports, and general mechanical service work requiring inch-system hardware. The black oxide finish provides moderate corrosion resistance in indoor and sheltered environments. This nut is appropriate for use by HVAC technicians, pipefitters, millwrights, and general mechanical contractors working with 7\/8-9 threaded fastener systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 12L14 steel construction for reliable strength in mechanical fastening\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers moderate corrosion resistance and low-glare appearance\u003c\/li\u003e\n  \u003cli\u003eIntegrated 1-3\/4 inch flange distributes load without a separate washer\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread for compatibility with standard inch-system bolts and studs\u003c\/li\u003e\n  \u003cli\u003eMeets TCMAI fastener standards\u003c\/li\u003e\n  \u003cli\u003eSold as individual unit with a minimum order quantity of one\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-system flange nut for use with 7\/8-9 UNC threaded bolts and studs in mechanical and structural fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, pipefitter, or HVAC technician familiar with inch-system fastener practices.
