Pocket screwdrivers are a set of screws of different types, different colors. These set of screws are found mostly by electricians, and these screws are used mostly for any work to do any electrical works. Selection of hand tools for cost-effective assembly and maintenance of a mechanical system has a significant impact on its life-cycle cost. A knowledge-based automated procedure for the selection of hand tools needed to efficiently carry out fastening operations in a mechanical assembly is presented. The objective is to select a tool that is applicable to a particular fastening operation, minimizes time and cost of the fastening operation, and satisfies accessibility requirements, and to provide design assistance to the design engineer. The role of the tool selection procedure in the concurrent design of mechanical systems is described.

Usage of screwdrivers:

Many different screwdrivers and bits of tubing will work, first, the screwdriver. One wants a short and small screwdriver, so as not to have too much strength on the end-bolts (finger-tip pressure is adequate), and one wants a screwdriver that fits the end-bolts just exactly. They make two models of what they call their "Pocket Screwdriver" because the blade (before it has its tubing added) can be reversed and telescoped into the handle for safe carrying in a pocket. These are nicer than most small screwdrivers, appropriate for special work. Each model is made in two sizes (A and B), and the larger B size is just exactly the right size to fit concertina end bolts This may seem like a lot of effort for a screwdriver, but anyone who has used the tubing trick will testify that it very nearly solves entirely the problem of slipping. At a minimum, any screwdriver that you are using now can be significantly improved by just buying a few inches of 4mm plastic tubing and putting it over the blade. You will still need screwdrivers without the tubing too, of course, for tasks other than end bolts--this makes a special screwdriver just for concertina end bolts.
