THUMBSCREW ZINC FOR PILASTER OR SHELF

A screw is a type of fastener, in some ways similar to a bolt typically made of metal, and characterized by a helical ridge, known as a male thread (external thread). Screws are used to fasten materials by digging in and wedging into a material when turned, while the thread cuts grooves in the fastened material that may help pull fastened materials together and prevent pull-out.

A screw drive is a system used to turn a screw. At a minimum, it is a set of shaped cavities and protrusions on the screw head that allows torque to be applied to it. Usually, it also involves a mating tool, such as a screwdriver, that is used to turn it. Other examples include Phillips head screws and screwdrivers, and Allen hex screws and wrenches.

Shelving used in foodservice storage and merchandising may be solid or wire. Solid stainless steel and wire shelving is used in a broad range of commercial applications. It is often used in restaurant, food service and retail store applications, as well as refrigerators and freezers, due to its ability to stay clean and resist rust and mold. A further finish on the steel may either be painted or sprayed on, or be it electroplated with zinc.
