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.
Nonconductive and resistant to many corrosives, Fiberglass is a good choice for applications threatened by salt water, oils, mild solvents, and other harsh environments. G-10 is a glass reinforced fiberglass, utilizing a continuous woven glass fabric laminated with an epoxy resin. The glass reinforcing increases tensile strength over non-reinforced fiberglass, G-10 in particular is rated at 38,000 psi (pounds per square inch range). G-10 exhibits a high tensile strength to weight ratio, approximately twice that of Aluminum 2024, for example. G-10 is very non-porous, and will only absorb 0.1% of water if left to soak for 24 hours. G-10 is flame retardant and will operate at temperatures up to 280 degrees without degrading. This material is recommended for applications where superior strength and excellent electrical insulative properties are required over a wide range of temperatures.
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.
- Machine Screws are often used with nuts or driven into tapped holes
- Fiberglass is suitable for applications where tensile strength to weight, non-conductivity and corrosion resistance are all important considerations
- 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
