Lok-Fast MTD Pistol-Grip Installation Tool, Composi-Lok

The S540MTD (Master Torque Driver) is a versatile pistol grip power tool capable of installing Jo-bolts, Visu-Loks, Visu-Lok IIs, Composi-Loks, Composi-Lok IIs, and Composi-Lok IIIs, in sizes ranging from 5/32″ (-5) up to 3/8″ (-12). The tool can be reconfigured to install different threaded blind bolt types and sizes by changing the adapter assembly.

To determine the correct tooling needed, first identify the type and style of fastener being installed. Note that Composi-Loks are not the same as Composi-Lok IIs, which utilize a drive nut to improve the installation process, thus requiring a different style of nose as well as a different type of wrench adapter. An adapter assembly is made up of two components, a driver assembly and a nose, which attach to the main tool, the S540MTD.
