4mm Machine Screw Round Head Phillips Nylon Transparent Plastic Mechanical

The 4mm machine screw is a screw with M4 external thread that used where it is necessary to reduce weight and insulation. The screws have a uniform diameter the entire length of the shaft as opposed to tapered screws that have a pointed tip. They are used to fasten machine components, appliances, and more. Ever Hardware provides custom-made 4mm machine screw and customizable packaging.

Phillips drive bits are often designated by the letters “PH”, plus a size code 0000, 000, 00, 0, 1, 2, 3, or 4 (by order of increasing size); the numerical bit size codes do not necessarily correspond to nominal screw size numbers.

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.
