Each pack contains 25 bolts, making it a practical quantity for job sites and maintenance shops. The 1\/2-13 designation indicates a 1\/2-inch nominal diameter with 13 threads per inch, conforming to standard Unified Coarse (UNC) thread specification. These bolts are driven with a standard hex head and are suited for general structural fastening applications. Plumbers, electricians, HVAC techs, and general contractors reach for this fastener when securing brackets, equipment supports, and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis bolt is appropriate for general-purpose fastening in residential and light commercial construction and mechanical installation work. Common use cases include mounting equipment bases, attaching structural brackets, and assembling support frames in HVAC, plumbing, and electrical rough-in work. The coarse UNC thread engages quickly and resists cross-threading, which matters on busy job sites. The 4-inch length accommodates thicker assemblies where shorter fasteners fall short. Sold in a 25-count box, this SKU suits both single-task jobs and ongoing service work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC coarse thread for fast engagement and reliable grip\u003c\/li\u003e\n  \u003cli\u003e4-inch length handles thicker structural and mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eLow carbon steel construction provides adequate strength for general-purpose fastening\u003c\/li\u003e\n  \u003cli\u003eStandard hex head compatible with common wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003e25-bolt pack quantity reduces reorder frequency on active job sites\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose 1\/2-13 UNC coarse thread hex bolt suitable for use with standard 1\/2-13 nuts and threaded inserts in typical structural and mechanical fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard hex wrench or socket set sized for a 1\/2-inch hex head fastener.
