Value Collection TCI41000250 Tension Control Bolt A490

Product Description

The VALUE COLLECTION TCI41000250 is a tension control bolt designed for structural steel connections requiring precise, torque-controlled installation. This bolt features a 1-8 UNC thread and measures 2.5 inches in length under the head with a 1.875-inch head diameter. Manufactured from A490 high-strength steel with a bright, uncoated finish, it meets ASTM A490 and ASTM F2280 standards. Each unit ships with a nut and washer included. Structural ironworkers and steel erectors rely on tension control bolts when pretensioned connections are required and direct torque verification is not practical with a standard impact wrench setup.

Tension control bolts are used in structural steel framing for commercial and industrial construction projects. They are installed in bearing-type and slip-critical connections where AISC and RCSC connection specifications require pretensioned fasteners. The splined end of the bolt shears off at the calibrated clamp load, providing a built-in installation verification without the need for a torque wrench or skidmore device. This fastener is suited for applications where A490 high-strength bolting is specified by the structural engineer of record.

Key Features

• A490 high-strength steel construction meets ASTM A490 and ASTM F2280 fastener standards
• 1-8 UNC thread with 2.5-inch length under head suits standard structural connection thicknesses
• 1.875-inch head diameter provides the bearing surface required for structural bolt applications
• Bright, uncoated finish — no coating variables affecting installation torque calibration
• Includes nut and washer — complete assembly ready for installation
• Package quantity of 5 with a minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement or direct procurement fastener for structural steel connections specifying 1-inch diameter, A490-grade tension control bolt assemblies per ASTM F2280.

Installation Notes

Installation of tension control bolts is performed by qualified structural ironworkers using an electric tension control wrench that engages the splined tip. Always verify that the connection material stack-up does not exceed the grip range for this bolt length before installation. Follow RCSC Specification for Structural Joints and applicable building code requirements for pretensioned bolt assemblies. Do not reuse tension control bolts once the splined end has sheared.
