“CORONET” DIRECT TENSION INDICATORS

The simplest, most efficient, most easily inspected device for guaranteeing bolt tension was invented by Cooper and Turner. Now in use in bridges and large structures throughout the world, “Coronet” Direct Tension Indicators are only available from Cooper and Turner. Diameter ranges from M12 (1/2”) to M36 (11/2”) in plain or sherardized* finish, and in general or higher grade for use with bolts to British and other national specifications. The products are supplied complete with full test certification, feeler gauges and instructions. * N.B. “Coronet” Direct Tension Indicators should only be used in the finish in which they leave the factory, otherwise we cannot be held responsible for the results.
