It features a 1-1\/4-7 UNC thread size with a 5-1\/2 inch length under head, and is partially threaded to allow for secure clamping in bolted connections. Manufactured from steel to ASTM A325 structural bolt standards and finished with a hot-dipped galvanized coating, this bolt provides corrosion resistance suited to exposed or high-moisture environments. It is installed by structural ironworkers, millwrights, and experienced tradespeople working with heavy steel assemblies.\u003c\/p\u003e\n\u003cp\u003eThis bolt is commonly used in steel-to-steel structural connections, heavy equipment mounting, bridge construction, and other applications governed by AISC or RCSC bolt specifications. The ASTM A325 grade designation makes it a recognized choice for high-strength structural bolted joints in both commercial and industrial settings. The hot-dipped galvanized finish provides added durability in outdoor or corrosive environments where plain finish fasteners would degrade quickly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM A325 high-strength structural bolt grade for load-bearing connections\u003c\/li\u003e\n  \u003cli\u003e1-1\/4-7 UNC thread with 5-1\/2 inch length under head\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for proper grip length in structural joints\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish for corrosion resistance in outdoor or wet environments\u003c\/li\u003e\n  \u003cli\u003eSteel construction meets ASTM A325 fastener standard\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; compatible with standard UNC hex nuts and washers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ASTM A325 structural hex bolt for use with standard UNC 1-1\/4-7 heavy hex nuts and structural washers in high-strength bolted connections per applicable structural fastener specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of ASTM A325 structural bolts should be performed by qualified tradespeople following RCSC Specification for Structural Joints guidelines. Always power down or de-energize adjacent systems before working in confined steel assemblies. Use calibrated torque wrenches or tension-control methods as required by the project specification.
