How Do Spanners Work

A spanner works for gripping a fastener and twisting it anticlockwise to tighten or loosen it. The profile of the head fits over, into the fastener, or around . When the head is rotated, friction (a force which shows down 2 objects moving passing one another). Between the fastener and the profile at the contact points causes the spanner to mechanically grip the fastener, providing a torque to rotate.

To turn the tool, the shaft needs to be turned on the plane at the fastener. Some users do this by gripping the shaft and pulling or pushing it. The shaft also acts as a lever, magnifying the force input by some users in order to turn the fastener easily.

How to fit a nut or bolt

Nuts and bolts are commonly a fastener which holds more or two work pieces together. They could have all the sorts of different head types and sizes. So, you would need to choose any spanner with the right profile that tightens to loosen them.

Fitting a bolt and nut

Step1- locate bolt holes

You may also need to drill the bolt holes, and they might already be in the work pieces. There is a bolt hole which needs to be slightly wider in diameter than the thread of the bolt. So, the bolt could slide through the holes easily.

Bolts which are more significant than you would need to drill pilot holes where the bolt hole has to be so the massive drill does not damage the workpiece. The pilot holes also act as guidance, drawing the drill into the correct place.

Step2- line up the correct bolt holes

Move the work pieces so that the bolt holes line up. If you have a Podger, push the spike end by the first hole and wiggle that around until it goes through the second hole.

Step3-Fitting the nut

Fit the nuts onto the exposed threaded ends of the bolt. Turn it clockwise with the fingers until it is too tight to turn.

Step4- use the spanner

Fit the spanner on the top of the nut. Some spanners also fit onto the nut from the side, other from above it.

•    Hold the shaft firstly and then turn it clockwise as far as you may go. If it is a ratchet spanner, turn it backward direction when you could not go any further, and then rotate it in clockwise direction again to tighten it. Keep doing this until the nut is tighten enough.

Step5- troubleshooting

If your bolt is spinning in the bolt hole and your nut is not tightened enough, use another spanner that could hold the head of the bolt still while you could tighten the nut.

Removing and putting the nut is not a difficult task if you have a good quality spanner, it could be that you may have spanner online. Numerous websites are dealing with tools, and people could do spanner online shopping  quickly and get reliable products.
