Hand Tools

A wrench is used to tighten nuts. Socket wrenches are a type of nut driver.

If you don't maintain them , they'll wear and break faster.

If you don't maintain them, they produce poorer results.

Dull cutting tools leaves a chewed-up cut instead of a nice, smooth one as an example.

When you can't use that tool any more, you'll either have to stop working while you go and buy a new tool - which will cost you both time and money.

Or pick a poorer tool and work slower, also costing you time.

Tools that get worn can also be dangerous, both to the user, to the surroundings and to other people around you. A tool that get you damaged will make you miss work, costing you time. A tool that destroys the piece you're working on, or something right nearby will force you to do repairs. That means added work and cost, and again lost time.

A tool that damages someone else can get you sued, or even jailed.

All good reasons to maintain your tools.

A small, sharp knife such as a paring knife or a steak knife will often reach deeply enough into the crosshair pattern of the screw's head. However, if the screw is in too tight, you might permanently twist the blade without loosening the screw. So, a pair of vise grips can be used to slightly crush the head of the screw in order to gain a grip. Pliers often just do not give enough grip, and channel locks are often too large and unwieldy for the circumstance.

Cannot be treated as a machine but a lever mechanism.

An Allen wrench, or "hex key" is tool used to turn Allen screws or bolts. They come in various sizes, both SAE and metric, and may be single, or foldable into little sets that look like Swiss Army Knives. The heads are far more unlikely to strip out than Phillips or slotted screws, and are often used in, and included with "assemble it yourself" furniture like Ikea stuff. You just insert the end in the screw and turn. Lefty-loosey-Righty-tighty.

Unfortunately nowadays not many hand or electric tools are made in US. Some companies make their best tools in America, Germany, Mexico or Japan. Of the popular makes almost all Ridgid, Stanley, Crescent, Porter Cable, Black and Decker, and Milwaukee have their cheaper tools made in China. . Tools are made everywhere but in my opinion the best are made in Germany, UK, Switzerland, Sweden, USA, Japan and Mexico I still use a 1985 DeWalt 384 rotary saw made in Mexico, almost every day.

a feeler guage cannot be calibrated, it is made at precise measurements that cannot be changed.

When a feeler guage is out of spec, it is replaced.

hammer

A cold chisel is one made from steel that is then tempered and is able to cut through other metals. Much used by metalworkers and blacksmiths.

They come in different weights and prices but a good Stanley 8 pound sledgehammer sells for aprox $30.

Impact sockets are made of softer metal.

Rather than a screw or bolt head having a single slot to take a screwdriver, a torx screw head system uses a six-pointed star shape, and a screwdriver designed to fit.

high carbon steel

2.25 mm is 3/32 inch

The 15 mm wrench, which is probably one of the most used wrenches.

Regular motor oil dissolves rust. Drench the bolt and wait two minutes. Use an oil-soaked rag, if necessary.

A length of pipe will do the trick. It just has to have a larger inside diameter than the wrench handle. The longer the pipe, the better the leverage. Electrical conduit pipe will work on small wrenches, but it is not very strong.

There are many measuring tools. The simplest example is a ruler. .

A lever works on the principle of using torque. A screw driver is used as a lever because the relatively broader handle produces much more torque for the same force as compared to the narrower blade of the screw driver.

A tape measure is a length of narrow tape of fabric, metal or fibreglass that has length measurements printed on it. If it's a standard metal tape measure it's mounted in a small container with a spring to wind it in. They come in lengths from 3 to 35 feet. 16 feet is the most common although many framers and carpenters like to carry a 25 foot version. Longer tape measures can be made of fibreglass and go up to 300 ft. with 100 being common. These are hand wound on a larger reel and much used by landscapers or road workers.

A vice grip is used to hold small objects tighter than regular pliers will.

That is a hammer with one flat side and one shaped like a ball. Used by furniture makers and engineers.

A gaucho knife is a knife used for utility and fighting. The knife is carried around by Argentinean men. Some even have their knife custom-made and designed with German steel, custom engravings, and more.

An Allen wrench is a hex head wrench - a screwdriver with a handle and hexagonal head at right angles to each other.

That depends entirely upon the circumstances: a good quick twist of a properly-placed screwdriver- at the right time- may save the lives of many; while a forcefully-driven screwdriver may seriously damage the health of another.

WARNING: If not utilized with care, a screwdriver may cause serious injury to the user. Considering the end prior to beginning... is always a good course of action.
