Abstract
An adaptor for applying a predetermined amount of torque to a bolt includes a housing having one end engageable with the bolt, and a shaft coaxially mounted within the housing and having an opposite end engageable by a wrench. The shaft and housing are clutch-connected by a spring-loaded friction disc assembly, which is carried by the shaft and adjusted to slip when the torque applied to the bolt reaches a predetermined value. A visual indicator is provided which measures wear of the friction discs. A thrust bearing is provided at the bolt end of the housing to minimize friction loss between the adaptor and the work.
