M6 PVC Hex Bolts DIN 933 Corrosion Resistant Polyvinyl Chloride Resin Cap Screws Machine Threaded Plastic Poly Gray Color Anti Acid Alkali Lightweight Insulated Fasteners

Description

M6 PVC hex bolts have a hexagonal head and machine threads for use with a nut or in a tapped hole. Hex cap screw features a washer face under the head and a chamfered point, whereas a hex bolt does not have a washer face or chamfered threads. Hex bolts are available with standard threading or full threading, depending on the length of the bolt. Applications for hexagon screw head bolts can vary from the exterior and automotive to marine, coastal, and high-temperature environments. Ever Hardware provides precision M6 PVC hex bolts 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. M6 PVC pan head screws are widely used on pipes/electric cables/construction/signs/clothing/furniture/healthcare/flooring/wire rope etc.
