  • Machine Screws are often used with nuts or driven into tapped holes
  • Super Tough Nylon 6/6 is a general purpose plastic that is suitable where high impact strength is important
  • Pan head allows for higher tightening torques
  • Phillips drive is designed to cam out under too much torque
  • Fine threads tap better into harder materials and thin walls, and are stronger in tension than coarse 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.

Super Tough Nylon is a modified Nylon 6/6 material which performs better at low temperatures. Impact Strength, as measured by the Izod impact test method (which measures force required to break material), is 17 pounds per foot. This is significantly tougher than standard Nylon 6/6, which is rated at 3 pounds per foot. Tensile strength is estimated to be 11,600 psi (pounds per square inch) at -40 degrees Fahrenheit. Nylon 6/6 is a general purpose thermoplastic with outstanding resistance to organic chemicals, acids and alkalis. Nylon wears well against other surfaces, it is readily machinable and may be milled, turned and cut with conventional machine tools. It does exhibit some dimensional swelling in wet applications which should be taken into account with its use.

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. The Phillips drive style was originally designed so that the driver would slip out under extreme torque, preventing over-tightening and damage to the fastener or the material.

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. Fine threads are preferable when working with harder materials or when threading into a thin material. They are also stronger in tension than coarse threads, and generally provide higher shear strengths.
