Designed for "F" Connectors, these wrenches help prevent over tightening. An audible click tells you the connection heads, sized for 7/16" F connectors and are designed with an ergonomic cushioned handle for user comfort and protection. The last two digits of the part number indicate the inch pounds of torque (either 20 or 30 inch pounds) and the first four letters indicate whether the head is a speed head or a full head (TWAF is full and TWAS is speed).
Note that these wrenches work in tightening mode only. Torque wrenches are 6 1/2" long
