Manufactured from Grade 2 steel with a hot-dipped galvanized finish, this bolt provides corrosion resistance suited for outdoor or moisture-exposed installations. The shank measures 1 inch in length under the head and is partially threaded, with a 7\/16-inch hex drive. It conforms to ANSI\/ASME B18.2.1 dimensional standards. Licensed tradespeople and maintenance professionals use this fastener across HVAC equipment mounting, plumbing support brackets, electrical enclosures, and general mechanical assemblies.\u003c\/p\u003e\u003cp\u003eThis bolt is a standard inch-series fastener appropriate for residential and light commercial trade work. Partially threaded shanks are commonly specified where a smooth unthreaded grip length is needed between clamped surfaces, reducing the risk of thread engagement in load-bearing zones. The hot-dipped galvanized finish makes it a practical choice for exterior mounting hardware, rooftop equipment support, and corrosion-prone environments where plain steel fasteners would degrade prematurely.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread form for compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n\u003cli\u003e1 inch length under head, partially threaded shank for proper grip in clamped assemblies\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction meeting general commercial fastener strength requirements\u003c\/li\u003e\n\u003cli\u003eHot-dipped galvanized finish for corrosion resistance in outdoor and wet environments\u003c\/li\u003e\n\u003cli\u003e7\/16-inch hex drive fits standard hex wrenches and sockets\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI\/ASME B18.2.1 and ANSI\/ASME B18.2.2 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use fastener for any application requiring a 1\/4-20 UNC hex head bolt with a 1-inch length under head and partially threaded shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 7\/16-inch hex wrench or socket driver. Always power down or de-energize equipment before replacing or installing fasteners on mechanical or electrical assemblies.
