Machine Screws are often used with nuts or driven into tapped holes
Isoplast is suitable where high strength and chemical resistivity are important
Pan head allows for higher tightening torques
Driven by a flat-bladed driver
Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads

Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.

Isoplast 101 LGF40 NAT is a type of polyurethane developed by Dow Plastics. This particular material has been reinforced with 40% glass fibers, which has the effect of increasing tensile strength to 27,000 psi (pounds per square inch), higher than glass reinforced Peek. Isoplast is also impact resistant, with an Izod Impact Rating of 8 force pounds, which compares favorably to 3 force pounds for Nylon 6/6. Isoplast is chemically resistant, and resists water absorption, retaining only 0.11% weight after 24 hours of exposure. Dielectric strength is 500 volts per millimeter, indicating this material may be suitable as an insulator.

Pan head fasteners have a low, large cylindrical head with a high rounded top edge for higher tightening torques - these fasteners are often recommended to replace older head styles such as round, binding, or truss-head where possible. Common applications for slotted screws include woodworking, although the drive style is not designed to be used with power drivers.

A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.
