Product name: PVDF screws
PVDF screws

Cross countersunk head screws are suitable for occasions where the nail head is not allowed to be exposed, but the corresponding tapered counterbore must be made on the surface of the parts with through holes. Commonly found in machinery, electrical appliances and buildings. Used to connect two connected parts. One of the parts is made through, and the other part is made of internal threaded holes. Cross countersunk head screws are divided into RENY glass fiber reinforced polyamide MXD6 polyphenylene sulfide PPS polypropylene PP polyvinyl chloride PVC polyether ether ketone PEEK polyvinylidene fluoride resin PVDF polytetrafluoroethylene resin PTFE polycarbonate PC nylon 6 /6 etc.

The most important physical performance indicators:

1. The joint between the head and the screw is torsion resistant

2. Whether the head groove, especially the cross head, fits the standard head size of the screwdriver.

3. The thread outer diameter, middle diameter and bottom diameter of plastic screws are standardized. Due to the water absorption of different plastics leading to size differences in different usage environments, this standard is not as strict as metal screws.

The most important chemical performance index

1. Acid resistance

2. Alkali resistance

3. Fire rating

4. Insulation performance

Advantages of plastic screws

1. Compared with ordinary metal screws, the greater advantage of plastic screws is that they have good insulation properties and are not conductive.

3. Fire rating

4. Insulation performance
