Torque wrench for spark plugs ?

Is a torque wrench necessary for replacing spark plugs ?

A mechanic can put alot together without a torque wrench, it comes with experience. Mechanics sees plenty of screwed up spark plugs and threads by amateurs, and if you don’t have more than five years experience, I suggest to use the torque wrench and do the job.

The plug needs to be tightened to the correct specification. If [..]

Tips for Using, Maintaining Torque Wrenches

User practices

1. Safety glasses or goggles should be worn at all times when using any hand tool.
2. Always follow the manufacturer’s directions regarding torque direction, proper force, torque pattern/sequence, use or non-use of lubrication on fasteners and torque “tighten/release” cycles.
3. Use a torque wrench to apply a specific torque value during the final assembly process. Do not use a torque [..]

Plug-in Connector Assembled without the Aid of a Torque Wrench

The first plug-in connector that can easily be assembled with a defined torque without the aid of a torque wrench is the Turck’s new M12Nm connector .
The integrated torque control guarantees an IP67 connection. The M12Nm connector was developed by Escha, a connector specialist at Turck Group.

Until now, a torque wrench has been the only way to ensure a plug-in connector was tightened with the correct [..]

Using Torque Wrenches

Most torque wrenches are required to be set at “0”when not in use to maintain calibration.
Please refer to the manufacturer’s instructions for further information on use and maintenance.

Setting Torque Value on a Dial Indicator Wrench:

1. Make sure your indicator needle is set to “0” [..].

Adjust torque wrench

Which torque wrench?
First you need to choose a torque wrench suitable for your needs. Let’s take a bike for example and we need to adjust my drive chain.
We can choose a cheap torque wrench like Halfords, that have a good quality and are accurate enough for most jobs.

We will also need a socket to fit each of the jobs, they are interchangeable with some socket sets [..]

Dial Torque Wrench

What unit of measurements is read on a dial torque wrench ?
The unit of measurements on a dial torque wrench is either foot pounds (usual on large wrenches), inch pounds (usual on smaller 3/8″ drive wrenches) or Newton/Meters (metric, either size). Some will have readouts for both ASE and Metric [..] .

Torque socket wrench

What is the Difference between a torque wrench and a socket wrench ?

A socket wrench is like a small steel tube – one end has ridges that fit precisely around a bolt. The other end often has an opening of 1/4″, 3/8″, or 1/2″ square. This end receives the protruded part of a ratchet with the same dimension.

Most torque wrenches look like a larger version of a ratchet[..]

Torque Arm | What is it | Who did you find it ?

Torque arm is the distance from the center of the axis to the point of the applied force.
It’s expressed in either in foot or inch pounds, in the imperial system.
The torque arm is often referred as force arm, lever arm, or moment arm.
In a lever, the moment (torque) arm of the force is often referred to as the force arm and that of the resistance is referred [..]

Convert a torque wrench from inch pounds to foot pounds

If you need to torque something let’s say to 16 Ft pounds, you can use also a torque wrench that measures “inch” pounds. So, how do I convert that ?

It is a simple its a simple math conversion. A foot pound is the torque you get when you apply a pound of force on the end of a 1 foot rod. So 1 ft*lb = 12 in*lbs.
Simply multiply your [..]
