Cabinet screwdrivers are made of long, small and round steel with a handle at one end and a tapered blade at the other end. The diameter of the handle is generally three to seven times the diameter of the shank and is made of wood or plastic. The shank does not need to be connected because it is not designed for tach/reinforcement.

The length of the screwdriver cabinet ranges from 75 mm to 500 mm with a proportional width and thickness of the blade and handle. Cabinet screwdrivers are designed to loosen and tighten screws in holes or tight areas. When cleaning rust or dirt from the screw slots, just use hand strength, do not use a hammer.

The blade and shank on these tools are much smaller than those on a standard screwdriver and will be more easily damaged. Do not use the screwdriver for prying or as a tool for chiseling.

This will result in the handle or tip breaking, damaging the tool and causing possible injury. DO NOT use pliers on the screwdriver cabinet as this will damage the teeth on the jaw and increase the strength of the shank. Leveraging with a screwdriver will also bend the screwdriver shank, which could damage the tool.

Bolt has fastens pieces together and because it is fastens things, it is also known in a group of a things that we use fasteners, a screw is another one for example for in the group of thing called fastener. I will explain about the head and the thread.

This is the head of the bolt, and if we take its measurement across the head of the bolt , this will give us the size of the spanner and wrench that we need to use to the bolt.

So, if the measurement across the head is 12mm, we need 12mm spanner/wrench.

A bolt also has thread. And we measure the diameter of the thread will give us the thread of the Bolt.

So if the diameter measure is 8 mm, we need to have no 8 bolt.

The thread on a bolt is cut , normally nowadays the thread is cut using a cnc machine, but for one a off piece, you also need to use die. You cut a thread an external thread with the die.

What you can do with a bolt, is tightened.

If you tighten it you move your spanner in a clockwise direction

You can also loosen a bolt and if you loosen a bolt, you turn the spanner in a counterclockwise.
