Applied Technical Services offers Skidmore Bolt Testing for clients looking for pre-installation verification tension and rotational capacity testing of structural fasteners, as well as general fastener testing to determine torque/tension relationships. Skidmore Bolt Testing verifies that the bolt assembly meets the required specifications and capacity, while also confirming whether the installers of the bolt assembly have followed correct procedures. Knowing exactly how much of the torque applied to meet the required amount of tension in the bolt assembly is not possible without this type of testing.
In the process of Skidmore Bolt Testing, also referred to as Pre-installation Verification Tension Testing and Rotational Capacity Testing, a bolt, nut, and washer assembly are inserted into the tension reading equipment. The assembly is tightened to simulate the conditions of installation into a steel connection, (for example, in the case of a Tension Control bolt) and the tension persists until the spline of the bolt shears off. ATS uses Skidmore Wilhelm’s hydraulic tension calibrator, which is the industry standard for testing on fasteners in tension-critical joints. Skidmore tension calibrators are required to be used on high strength bolts utilized in the construction of buildings, bridges, and other major structures.
ATS conducts Skidmore Bolt Testing procedures within its Mechanical Testing Division. Our labs are operated by trained experts who are familiar with the methods of using Bolt Tension Testers capable of handling up to 170,000 pounds to test components such as: Hex Bolts, Tension Control Bolts, Anchor Bolts, Studs, Lock Nuts, and Direct Tension Indicating Washers. Our certified mechanical testing personnel follow the high strength structural bolt system requirements of AISC/RCSC and ASTM F3125.
