Manufactured to ASTM A490 and ASTM F2280 standards, this bolt features a 1-8 UNC thread and a length under head of 2-3\/4 inches. The splined end breaks off at a calibrated torque, confirming that proper pretension has been achieved without the need for torque wrenches or manual inspection. Each package includes the bolt, a compatible nut, and a washer. Installation is performed by ironworkers and structural steel crews on job sites governed by AISC and RCSC bolt specifications.\u003c\/p\u003e\n\u003cp\u003eThis tension control bolt is suited for structural steel connections in commercial and industrial construction, including beam-to-column connections, moment frames, and shear tab assemblies where ASTM A490 high-strength fasteners are specified. The 1-7\/8 inch head diameter and UNC thread form are consistent with standard structural bolt patterns. Supplied in a package of 5 per unit, this fastener is appropriate for use wherever the engineer of record specifies high-strength TC bolts meeting ASTM F2280.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM A490 material grade for high-strength structural applications\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM F2280 tension control bolt standard\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC thread form with 2-3\/4 inch length under head\u003c\/li\u003e\n  \u003cli\u003eSplined end confirms pretension when sheared — no torque wrench required\u003c\/li\u003e\n  \u003cli\u003eIncludes nut and washer in each set\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish; 1-7\/8 inch head diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style structural replacement for high-strength tension control bolt applications requiring ASTM A490 and ASTM F2280 compliance in 1-8 UNC thread size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTension control bolts are installed by qualified ironworkers using an electric TC wrench that engages the splined end. Power down or de-energize any adjacent electrical systems before working in the installation area.
