This Grade A325 steel fastener uses a splined end that shears off when the bolt reaches its specified installation tension, giving the installer a positive indication of proper torque without a torque wrench. Each assembly includes a compatible nut and washer. The bolt measures 6 inches under the head with a 1-7\/8 inch head diameter and a 1-8 UNC thread. It ships in a 5-piece package with a minimum order quantity of 1.\u003c\/p\u003e\n\u003cp\u003eTension control bolts of this specification are used in structural steel erection for buildings, bridges, and heavy steel frames where high-strength bolted connections are required. They are appropriate for slip-critical and bearing-type connections per ASTM A325 and ASTM F1852 standards. Installation is typically performed by ironworkers and structural steel crews using an electric or pneumatic TC bolt installation tool that engages both the nut and the splined tail simultaneously.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSplined tail shears at the target clamp load, confirming proper installation tension without a torque wrench\u003c\/li\u003e\n  \u003cli\u003eGrade A325 steel construction meets ASTM A325 and ASTM F1852 fastener standards\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC thread form for compatibility with standard structural nuts\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for painted or galvanized structure applications\u003c\/li\u003e\n  \u003cli\u003eIncludes matching nut and washer for a complete installation assembly\u003c\/li\u003e\n  \u003cli\u003ePackaged in 5-piece quantities for jobsite and inventory management convenience\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ASTM A325 and ASTM F1852 compliant tension control bolt for standard structural steel bolted connections using 1-inch nominal diameter high-strength bolt holes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a TC bolt installation tool rated for 1-inch structural fasteners.
