It features a 7\/8-9 UNC thread, a 3-1\/4 inch length under head, and a 1-5\/8 inch head diameter. Manufactured from A490 alloy steel with a bright uncoated finish, this fastener meets ASTM A490 and ASTM F2280 standards. Each package includes the bolt, a compatible nut, and a washer. Structural ironworkers and steel erectors install these fasteners wherever high-strength bolted connections are specified by engineering drawings or steel construction codes.\u003c\/p\u003e\n\u003cp\u003eTension control bolts are used in structural steel framing for commercial and industrial construction. They are specified in connections requiring controlled bolt pretension, such as moment frames, column splices, and beam-to-column connections. This fastener ships in a package quantity of five, making it suitable for small-lot procurement or sample ordering. Installation is performed by qualified structural ironworkers following AISC and RCSC connection specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC thread for standard structural bolt hole patterns\u003c\/li\u003e\n  \u003cli\u003eA490 high-strength steel construction meets ASTM A490 and ASTM F2280 standards\u003c\/li\u003e\n  \u003cli\u003e3-1\/4 inch length under head accommodates standard structural steel stack-ups\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for painted or galvanized contact surfaces\u003c\/li\u003e\n  \u003cli\u003eIncludes matching nut and washer for complete installation\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 5 per unit for flexible ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit structural fastener for high-strength bolted connections requiring ASTM A490 and ASTM F2280 compliant tension control bolts with 7\/8-9 UNC threading.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of tension control bolts must be performed by qualified structural ironworkers in accordance with RCSC Specification for Structural Joints requirements. Use a compatible TC bolt installation tool that engages the splined end to achieve the specified pretension. Do not reuse tension control bolts once the splined end has been sheared.
