50x Natural Glass Filled Nylon Socket Head Screws M4 x 20mm, Nuts & Washers

BP1: 50x Bolts, 50x Nuts, 50x Washers. Material: PA 66 / 50% GF. Type: Socket Head Bolts. Length: 20mm. Diameter: 4mm. Pitch: 0.7mm. SKU: 813.. BP2: The addition of 50% glass fibers enhances the heat deflection temperature, enabling the material to perform reliably at elevated temperatures.. BP3: Glass fibers improve tensile strength, stiffness, and impact resistance while reducing the material's susceptibility to creep under load.. BP4: The composite also possesses superior hardness, surface durability, and wear resistance compared to PA66.. BP5: Repeated removal and refitting possible with excellent resistance to stripping in high torque applications.. || PRODUCT DESCRIPTION SUMMARY: While the melting point remains largely unchanged, the heat distortion temperature of PA66+GF (glass fibres) is superior to that of PA66, meaning that the composite can withstand higher temperatures before beginning to deform under load. The composite exhibits reduced moisture absorption, a significant improvement over PA66's susceptibility to moisture. Common applications include automotive components, industrial machinery and consumer goods where high strength and thermal resistance are required. Socket-head bolts and screws are also known as hex socket screws, plastic bolts and plastic machine screws.. || Please see the technical image illustration for size references.
