'Torque' is rotational or twisting force and is usually measured in Newton-meters 'N⋅m'

Torque wrenches ensure that the correct fastening torque is applied to get the correct tension within a critical fastener and bolted joint

Step 2 of 12

Some examples of critical joints:

  1. Trailcore Chassis mounts to Body

  2. Trailcore Chassis mount to chassis

  3. Towbar/drawer bar chassis bolts

<p><strong>Before using any Torque wrench</strong>&nbsp;- check the calibration date&nbsp;is valid</p><p><em>If out of date, notify your team leader</em></p><p></p><blockquote><p>IMPORTANT NOTE:&nbsp;</p><p>Any critical gauge such as Torque Wrenches, that are dropped or suspected of damage must be immediately <strong>removed from use</strong>, and submitted to the Production Engineer  for inspection or re‑calibration.</p></blockquote><p></p><p></p>

Before using any Torque wrench - check the calibration date is valid

If out of date, notify your team leader

IMPORTANT NOTE: 

Any critical gauge such as Torque Wrenches, that are dropped or suspected of damage must be immediately removed from use, and submitted to the Production Engineer for inspection or re‑calibration.

Step 4 of 12
<p>Identify Torque requirement for the fastener from Knowby or Fitting Instruction&nbsp;</p><p><em>This may be at your station or amongst a fitting instruction&nbsp;</em></p>

Identify Torque requirement for the fastener from Knowby or Fitting Instruction 

This may be at your station or amongst a fitting instruction

Step 5 of 12
<blockquote><p>Set Torque to the required setting - lock setting in place - Never assume setting is correct from last user</p></blockquote><p></p>

Set Torque to the required setting - lock setting in place - Never assume setting is correct from last user

Step 7 of 12

Ensure you are in a stable position while using to avoid injury, where possible, pull towards yourself vs. pushing towards the vehicle

Step 8 of 12
<p>Ensure rigid socked is used with Torque wrench (NOT and articulated socket)</p>

Ensure rigid socked is used with Torque wrench (NOT and articulated socket)

Step 9 of 12

Mark off fastener once torque setting met using suitable paint marking pen

10
Step 10 of 12

CQC: Follow single-piece-flow on completing torque/marking process

Torque-Mark-Torque-Mark

NOT Torque-Torque-Mark-Mark

11
Step 11 of 12

Sign off QC once all fasteners are correctly torqued and marked off
