Use and Care of Handtools and Measuring Tools
The purpose of this course is to increase your knowledge of the use and care of handtools and measuring tools.
No matter how small the job, safety precautions must be taken at all times. A tool may be efficient, essential, time-saving, or even convenient; but it is also dangerous. For this reason, handtools must be used correctly. You must also be alert to any conditions that might endanger yourself or fellow workers.
This course covers a large group of general purpose handtools. These tools are termed non-edged handtools because they are not used for cutting purposes and do not have sharpened or cutting edges. They are designed to facilitate mechanical operations such as clamping, hammering, twisting, turning, and more. This group includes such tools as hammers, mallets, and screwdrivers, which are commonly referred to as driving tools. Other types of non-edged tools include wrenches, pliers, clamps, pullers, soldering irons, and many others of a similar nature.
This course also covers measuring tools that are designed for measuring work accurately. They include level indicating devices (levels), noncalibrated measuring tools (calipers, dividers, trammels) for transferring dimensions and/or layouts from one medium to another, calibrated measuring tools (rules, precision tapes, micrometers) designed to measure distances in accordance with one of several standards of measurement, gages (go and no-go gages, thread gages) which are machined to predetermined shapes and/or sized for measurement by comparison, and combination tools such as a combination square which is designed to perform two or more types of operations. In this course five types of measuring tools will be discussed. These types are: scribers; rules or scales; calipers and dividers; micrometers; and miscellaneous measuring gages.
