You sometimes see the two-pronged spanner bit in your mechanical engineering hand tools screwdriver set, used to prevent tampering with bathroom stall doors.

Ratcheting screwdriver sets also include Posidriv screw bits, used to avoid "cam-out" or slippage from the slot of Phillip's head screws, and the bow-tie-shaped clutch screw, which was mechanical engineering hand tools used in automobiles between andas well as in travel trailers, as late as the s.

Mechanical engineers often have to cut and strip wires, so most carry at least one multi-tool with pliers. This tool might also include a sharp tool for piercing sheet metal, a pair of mini scissors, and several flat-head or Phillips head drivers.

This multitool allows the mechanical engineer to reattach broken, corroded or loose wires, to restore functionality. Calipers have two legs instead of just the one, and they are curved.

You use inward-curving calipers to measure outside diameters. The tips of each leg curve outward for mechanical engineering hand tools inside diameters.

All three of these tools ensure that vehicle performance stays "on spec" or within the recommended manufacturer's specifications. Camber measures the inward or outward mechanical engineering hand tools of the tire and the pavement.

Zero camber creates a degree angle between the roadway and the center line of the tire.

Cross Cut Chisel This type of chisel has a parallel sided blade with a narrow pointed end as can be seen from the figure below. Due to this shape it is useful to chip square or rectangular shaped grooves. There are other types of chisels as well such as bull nosed chisels etc which are used for different purposes but this much mechanical engineering hand tools should suffice to give you an idea about chisels and their uses.

In the next article we will take up screwdrivers for study. Screw Driver A screw driver is one of the most common tools which mechanical engineering hand tools not only found in mechanical workshop, but literally in every home.

Screw drivers come in various shapes and sizes and this article is dedicated to the study of screw drivers of different kinds. Plain Mechanical engineering hand tools As the name suggests this is the most commonly found screwdriver and consists of a steel blade having a flattened end which is case-hardened to withstand twisting force when it is inserted and twisted inside the base of the slot of the screw.

The handle is either made up of plastic or wood depending on its usage, the former being used for lighter works while wood being normally used for lengthier screwdrivers used for heavy duty uses. A mechanical engineering hand tools of this type of screwdriver is where the steel extends till the other end handle end and has portions of wood riveted to it for a better grip.

This type of screwdrivers can be used to apply much greater torque without the fear of the screwdriver failing by relative slipping between the steel blade and the handle.

The portion of the handle which is covered with wood gives a better grip as compared to if it were only a full steel handle.

The ends of the screwdriver normally are either plus shaped or minus shaped Ratchet Type Screwdriver If you are tightening or loosening a screw, then every time your hand reaches the rotation limit you have to pull out the screwdriver from the slot in the screw head, turn the screwdriver to the appropriate angle and reinsert it.

Plain pliers consist of two jaws which are hinged at a common point and are slightly tapered at the ends having very small teeth on the inside of the jaws. These teeth are more for having a firm grip on anything mechanical engineering hand tools between the jaws rather than having any purpose to cut that object.

Some pliers like the one shown in the figure below does have arrangements for cutting mechanical engineering hand tools as well both in the middle of the jaws as well as in the back side of the jaws.
