  • Machine Screws are often used with nuts or driven into tapped holes
  • Ceramic is suitable where primary considerations are high temperature and corrosion resistance
  • Flat head style allows fastener to sit flush to the surface
  • 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.

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.

Flat head fasteners are designed to fit flush to the surface when used with countersunk holes. Length is measured from the top of the head. 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.
