The square neck seats into the work material to prevent rotation during installation, eliminating the need to hold the bolt head while tightening the nut. Built from 18-8 stainless steel with a bright uncoated finish, this bolt offers solid corrosion resistance for both indoor and outdoor use. The thread is cut to Unified National Coarse (UNC) standard at 3\/8-16, and the shank measures 4.5 inches in length under the head.\u003c\/p\u003e\u003cp\u003eThis carriage bolt is suited for general structural and mechanical fastening tasks across plumbing, electrical, HVAC equipment mounting, pool equipment frames, and general construction. The 18-8 stainless steel construction makes it appropriate for damp or corrosive environments where standard zinc-plated fasteners would degrade. It is commonly used by trade professionals and contractors when assembling equipment supports, brackets, treated lumber connections, and similar structural assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-16 UNC thread for broad nut and hardware compatibility\u003c\/li\u003e\n\u003cli\u003e4.5-inch length under head suits medium-depth fastening applications\u003c\/li\u003e\n\u003cli\u003e18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments\u003c\/li\u003e\n\u003cli\u003eSquare neck locks into substrate to prevent spinning during nut tightening\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating to chip, flake, or contaminate the joint\u003c\/li\u003e\n\u003cli\u003eInch measurement system; meets standard UNC thread specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard UNC carriage bolt for use with 3\/8-16 hex nuts, washers, and threaded inserts in structural and equipment-mounting applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by hand-tool or power-tool trades depending on the application.
