Black plastic knobs made of durable and quality material with a threaded thru-hole allowing finger space and stand-a-way space from the milling part. These RoHS compliant knurled knobs are made of glass fiber reinforced plastic with a black matte finish. Tapped inserts and threaded studs are made of zinc-plated, blue passivated steel, or of stainless steel. The tapped inserts are standard hexagonal nuts, which are press-fitted in by machine. The threaded studs are press-fitted in by machine. Cover caps are glass fiber reinforced plastic with a light gray matte finish. Other cap colors as well as printed lettering on caps are available upon request. Knurled knobs feature an attractive and ergonomic design. They also offer the advantage of a closed shape (no recesses on the underside) suitable for applications with hygienic requirements. Ever Hardware provides custom-made fasteners and customizable packaging.

A bolt is a form of threaded fastener with an external male thread. Bolts are thus closely related to, and often confused with, screws.
The distinction between a bolt and a screw is unclear and commonly misunderstood. There are several practical differences, but most have some degree of overlap between bolts and screws.
The defining distinction, per Machinery’s Handbook, is in their intended purpose: Bolts are for the assembly of two unthreaded components, with the aid of a nut. Screws in contrast are used with components, at least one of which contains its own internal thread, which even may be formed by the installation of the screw itself. Many threaded fasteners can be described as either screws or bolts, depending on how they are used.
