Looking for the instruction set for the LTCR preset torque wrench with a fixed ratchet? Scroll down to the bottom of the page and the instruction set is available for download.

Please note that these wrenches click in one direction meaning that they apply and measure torque in the clockwise direction. This preset torque wrench comes with an arrow engraved on the case that calls out which direction torque will be applied and measured. You can use this tool to loosen a fastener in the counterclockwise direction, but you will NOT be able to measure the amount of applied torque.

When the wrench clicks, the designated amount of torque has been applied. Stop pulling. Continuing to pull after the wrench clicks can increase the applied torque to a value that exceeds the engineering specification.

The handle on the wrench looks soft. Is it?

This preset ratcheting click wrench comes with a dual grip configuration. It has an inner and outer grip. The inner grip is Sturtevant Richmont blue and you can see a small portion of the inner grip, giving it a stylish look.

The inner grip is made from Plastisol and has a Durometer rating of A65 +/-5/

The outer grip comfort factor owes its characteristics to the PVC Foam construction. The Durometer says it has a Shore rating A53 +/-5.

The slightly softer handle over the harder handle provides excellent grip control while making the tool very comfortable in the operator's hand.

Applications

Preset Ratcheting Square Drive torque wrenches are ideal for any application where:

The fastener or fitting to be tightened can be engaged with a socket.
The same torque is to be applied repeatedly.
It is advisable to eliminate the possibility of having the operator set the wrong torque on the tool.
A higher amount of rotation or limited access requires ratcheting to achieve the desired torque.
High operator efficiency is needed.
The simplicity of operation is needed.
Very high durability is needed.

The LTCR-Series tools are superb for these types of industrial assembly applications.

Features and Characteristics

LTCR-Series torque wrenches have +/- 4% Indicated Value Accuracy from 20% to 100% of capacity, meeting or exceeding the requirements of ASME B107.300-2010 and ISO 6789.
When we preset the torque value for you at the factory, we include a free Certificate of Calibration from our ISO 17025 Accredited Lab.
Error Proofing By Design flattened case prevents side loading.
The flattened case provides support for the click mechanism so the wrench is easier to calibrate and it holds calibration longer.
Error Proofing By Guidance creates excellent tactile and audible pulse when the preset torque is achieved.
Cushioned comfort grip plus lightweight for excellent ergonomics.
Slide pin ratchet provides excellent strength and durability.
Easy to install Ratchet Renewal Kit is available.
The torque is preset and locked in with a special tool.
Combination Adjusting and Release Tool (CART) P/N 819117 allows the operator to easily adjust torque on all SLTC, SLTC, LTC, LTCR, and LTCS wrenches.
Torque can be set using any unit of measurement.
Can be ordered preset from the factory or you can set the torque with your own torque tester.
Wrench measures torque in the clockwise direction.
