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.
Ceramic is produced from low pressure injection molded ceramics, utilizing 99.8% fully dense aluminum oxide (Alumina A998). In addition to the outstanding electrical insulation properties of alumina, this material offers unusual resistance to high temperature, corrosion, and abrasion.
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.
