Simplest solution for properly tensioning bolts
TurnaSure manufactures simple washer type load cells known as a Direct Tension Indicator or a Load Indicating Washer. TurnaSure's legacy company invented this brilliant concept of bolting technology. When this washer device is compressed while tightening a bolt or stud, the required clamp load is indicated in the fasteners and induced in the bolted joints. TurnaSure was the world's first company to devote all its energies to developing and supplying this unique fastener.
