Plastic Head Thumb Screws Male Threaded Clamping Fluted Black Knob

The plastic head thumb screws with 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 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 plastic head thumb screws and customizable packaging.

Nylon is a generic designation for a family of synthetic polymers, more specifically aliphatic or semi-aromatic polyamides. They can be melt-processed into fibers, films, or shapes. The first example of nylon (nylon 6,6) was produced on February 28, 1935, by Wallace Carothers at DuPont’s research facility at the DuPont Experimental Station. Nylon polymers have found significant commercial applications in fibers (apparel, flooring, and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging). Use these Nylon Spacers with bolts and screws to maintain space between the head and the surface. These spacers are constructed from durable nylon material. Nylon helps with vibration and corrosion resistance. After the initial commercialization of nylon as a fiber, applications in the form of shapes and films were also developed. The main market for nylon shapes now is in auto components, but there are many others.
