Product Description
Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.
Polyvinylidene Fluoride, or PVDF, has a useful temperature range of -148 to 300 degrees Fahrenheit. PVDF exhibits similar properties to Kynar, a trade name of the Arkema Corporation. PVDF is generally used in applications requiring high purity, strength, and resistance to solvents, acids, bases and heat. It also generates little smoke during a fire event. 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 1.2 foot pounds (on the Izod Impact Scale) as compared to 9000 psi, and 3 foot pounds, respectively. PVDF is stronger than PTFE and could be desirable where PTFE is not strong enough for the application. PVDF will absorb little or no water after 24 hours of exposure (less than 0.05% of weight impact). PVDF also has below average dielectric strength of 260 volts per millimeter (compared to 500 volts/mm for Nylon).
Flat head fasteners are designed to fit flush to the surface when used with countersunk holes. Length is measured from the top of the head. Common applications for slotted screws include woodworking, although the drive style is not designed to be used with power drivers.
A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings. Top to learn more
Great product but appears to run JUST a little short
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 small taper and I was unable to get the threads to grab. Not a big deal, I just ordered 1/8" longer screws. 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). Top to learn more
