PVDF exhibits below average strength as compared to Nylon 6/6, with tensile strength ranging from 5000 to 7000 psi (pounds per square inch) and impact strength of 1. PVDF exhibits below average strength as compared to Nylon 6/6, with tensile strength ranging from 5000 to 7000 psi (pounds per square inch) and impact strength of 1. There isn't much room for error in my application (replacing screws in a crank open window) and while the total length of the screw itself is fine, the threads don't extend all the way to the extreme end of the screw because there is a very, very... Product Description Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. Product Description Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. Common applications for slotted screws include woodworking, although the drive style is not designed to be used with power drivers. I don't have much experience with plastic screws, so perhaps this is typical (or perhaps the engineering diagram that specified screw sizes was a bit off). PVDF also has below average dielectric strength of 260 volts per millimeter (compared to 500 volts/mm for Nylon). PVDF also has below average dielectric strength of 260 volts per millimeter (compared to 500 volts/mm for Nylon). 2 foot pounds (on the Izod Impact Scale) as compared to 9000 psi, and 3 foot pounds, respectively. 2 foot pounds (on the Izod Impact Scale) as compared to 9000 psi, and 3 foot pounds, respectively. PVDF is generally used in applications requiring high purity, strength, and resistance to solvents, acids, bases and heat.
