Threading and Head Types

Machine screws
Industry relies on quality machine screws to attach metal and more. The definition of a machine screw is similar to that of a small bolt. A machine screw does not taper at all, resulting in a blunted end. A screwdriver is used to fasten the screw in place and rarely a wrench is used. Most companies find the screwdriver style heads easier to use because they allow for faster retightening. The threading of a machine screw can be customized to meet your project guidelines. It is likely that one of the many standard threading is what you will need though.

Metal Thread Forming
Metal thread forming screws have raised threading that fits into machined grooves. When driven into wood and some plastics, a metal thread forming screw will imprint a thread pattern into the material. There are numerous types of metal thread forming screws such as Type A, AB, or B Tapping screws which have a tapered point. Type A is used in thinner metals of 0.015-0.050 inches thicknesses. They can be used with sheet metal, plywood, and other materials. Type AB is used in thicker metals of up to 0.200 inches. They can be used on the same types of materials as Type AB and have a sharper point and more closely spaced threading than Type A. Type B is a blunt tipped thread forming screw that is used for thick metal sheeting, plastics, asbestos, and plywood.

Plastic thread forming (trilobular)
These specialty screws are made specifically for fastening to plastics and no other materials. They feature deep threading that provides a tight fit with the plastic it is being used with. This means that screws stay tight, with less maintenance over time compared to other plastic screws. The trilobular design means that screws are easier to drive as well.

Screw Head Types
Microscrews come in a variety of head types. Some of the more common varieties are Binding, Cheese, Fillister, Flat, Button, and Hex, Hex Trim, Oval, Pan, Round, and Truss. The type of head you choose depends upon the project you need it for. One or the other might be a better fit.
