The slotless machine screws are also known as thumb screw or grip screws. Knurling is a manufacturing process, typically conducted on a lathe, whereby a pattern of straight, angled, or crossed lines is cut or rolled into the material. The operation is performed for producing indentations on a part of a workpiece. Knurling allows hands or fingers to get a better grip on the knurled object than would be provided by the originally smooth metal surface. Occasionally, the knurled pattern is a series of straight ridges or a helix of “straight” ridges rather than the more-usual criss-cross pattern.

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high salinity, or poor air-circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure.
