Tension control bolts are engineered for high-strength structural steel connections, using a splined end that shears off at a calibrated torque to confirm proper installation tension without the need for a torque wrench. Each package includes a matching nut and washer. This fastener meets ASTM A325 and ASTM F1852 standards, making it suitable for steel-to-steel structural assemblies in commercial and industrial construction. Installation is performed by ironworkers and structural steel erectors.\u003c\/p\u003e\n\u003cp\u003eThis tension control bolt is designed for use in structural steel framing connections where high-strength, pre-tensioned fastening is required. Common applications include beam-to-column connections, moment frames, and bolted splice plates in commercial buildings, bridges, and industrial structures. The 3-1\/4 inch length under head accommodates standard structural connection stack-ups. Sold in a package of 5 with one nut and one washer per bolt included in the package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC thread size for compatibility with standard structural bolt holes\u003c\/li\u003e\n  \u003cli\u003e3-1\/4 inch length under head suits typical multi-ply structural connection stack-ups\u003c\/li\u003e\n  \u003cli\u003eA325 structural steel grade meets ASTM A325 and ASTM F1852 requirements\u003c\/li\u003e\n  \u003cli\u003eSplined end shears at calibrated torque, confirming full pre-tension without torque wrench verification\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for bare steel applications\u003c\/li\u003e\n  \u003cli\u003eIncludes matching nut and washer per bolt\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for standard 7\/8 inch structural bolt holes in ASTM A325-specified steel connections per AISC and RCSC bolt specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eTension control bolts are installed by qualified ironworkers or structural steel erectors using a compatible electric tension control wrench that engages both the nut and the splined tip. The splined end shears flush when the bolt reaches the specified minimum pre-tension, serving as the installation indicator.
