M5 PVC Pan Head Screws DIN 7985 Phillips Drive Machine Threaded Plastic Round Cross Phil Bolts Gray Color Corrosion Resistant Acid Alkali Lightweight Fasteners

Description

M5 PVC pan head 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. A screw thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter called a tapered thread. A screw thread is the essential feature of the screw as a simple machine and also as a fastener. Ever Hardware provides precision M5 PVC pan head screws and customizable packaging.

PVC has high hardness and mechanical properties. The mechanical properties enhance with the molecular weight increase but decrease with the temperature increasing. The mechanical properties of rigid PVC (uPVC) are very good; the elastic modulus can reach 1500-3,000 MPa. The soft PVC (flexible PVC) elastic limit is 1.5–15 MPa.
The heat stability of raw PVC is very poor, so the addition of a heat stabilizer during the process is necessary in order to ensure the product’s properties. Traditional product PVC has a maximum operating temperature around 140°F (60°C) when heat distortion begins to occur. Melting temperatures range from 212°F to 500°F (100°C to 260°C) depending upon manufacture additives to the PVC. The linear expansion coefficient of rigid PVC is small and has good flame retardancy, the limiting oxygen index (LOI) being up to 45 or more. The LOI is the minimum concentration of oxygen, expressed as a percentage, that will support combustion of a polymer and noting that air has 20% content of oxygen. M3 PVC pan head screws are widely used on pipes/electric cables/construction/signs/clothing/furniture/healthcare/flooring/wire rope etc.
