INFO: The current metal handle design was introduced in autumn 2016. Before that (more precisely, since 1986), models with a capacity of up to 250 ft/3000 i/340 Nm were equipped with a rubber handle – recognisable by the item number beginning with R8101nn. Even older Richmont torque wrenches in this series were known as ‘Model F’ and also had a metal handle at that time.

Micrometer Adjustable Clicker Wrench with Fixed Square Drive

When rapid adjustment and minimal fastener rotation are the need, these are the answer. Micrometer Adjustable Fixed Square Drive torque wrenches are ideal for any application where:

The fastener or fitting to be tightened can be engaged with a socket,
The user changes from one torque to another often,
A low amount of rotation does not require ratcheting to achieve the desired torque,
The ability to select the torque and lock it in rapidly is needed,
Simplicity of operation is needed,
Very high durability is needed.

These needs are common in small quantity assembly operations and many maintenance functions; the SD-Series tools are superb for these types of applications.

A simple thumbscrew mechanism locks handle to avoid unintended changing of torque setting. The strong dimensioned torque spring is the very heart of this clicker wrench. With reaching the pre-set torque, the torque spring is squeezed slightly, and the hardwearing pawl is releasing the tool tang. An excellent tactile and audible impulse signals that the pre-set torque is achieved. The well-proven neoprene rubber grip offers oil and chemical resistance, as well as cushioning and firm grip for good ergonomics.

Specification as stated by manufacturer. It is recommended to use in moderate performance range (approx. 1/3 to 4/5 of rated capacity). If you were to regularly work at the tool’s capacity limit, a larger model would generally be the better option.
