Determined by the shape formed by the screw's flank and crest, some common types of screw threads include metric, unified, buttress screw, round and trapezoidal. Other important identifying features of a screw thread include its thread form, thread pitch, major diameter, pitch diameter and minor dia

Size six ear gauges are considered to be larger than average. Most earlobes are initially pierced with an 18- or 20-gauge needle. Gauge sizes typically range between size 20 and 00, with 00 being the largest.

The zero error of a micrometer screw gauge occurs when the flat end of the screw touches the stud or anvil, and the gauge reads other than zero. If there is an error, it results in a positive or negative calculation. However, well-calibrated micrometers that are in good condition measure close to ze

Gauge, when applied to sheet metal, is used to determine the thickness of a single piece of sheet metal, with lower numerical values indicative of increasing levels of thickness. There are a number of standard gauge measurements in use, each with slightly different standard thickness.

A pressure gauge allows a fluid to enter from the item or equipment being measured and reacts by moving a calibrated rod inside it. The pressure can be correctly read when the rod has moved to its maximum position.

Modern cars use electric temperature gauges to keep track of radiator and engine temperature. They operate like a voltmeter, with a special hairpin-like assembly opening and closing to create an electrical circuit. Old cars used a Bourdon Tube, which is a mechanical temperature gauge.

Rotating a screw advances a spiraled incline into a surface. The head of a screw functions as a lever, while its threading is just a long incline that has been wrapped around a vertical shaft.

There are two main parts to a fuel gauge: the sender and the gauge. The sender is a float that is in the car's gas tank. The sender tells the gauge how much fuel is left in the tank, and this information is displayed on the dash of the car.

Fuel gauge problems are commonly the result of faulty electrical grounding at the tank or a problem with the sending unit inside the tank but can also be caused by faulty wiring or a bad fuse. Troubleshooting the problem involves a process of elimination that includes each of these as a possible roo

To use threaded hooks, install them in a wall or ceiling, and hang items from them. Threaded hooks are available in a range of sizes. The small hooks are suitable for holding up light items such as Christmas tree lights, while larger hooks can support tools and other heavy objects when they are inst
