Fine thread collated screw introduction

fine thread collated screw

Fine thread collated screw is collated screw with 50 pcs fine thread drywall screws installed in one plastic strip strip and is used for installing fine thread screws to metals or other harder surfaces. The fastening effect of fine thread drywall screws is better for high-strength metal materials. Fine thread drywall screws have a smaller pitch, so they are more conducive to self-locking and anti-loosening. And having more threads can reduce the effect of leakage and achieve the effect of sealing. However, fine thread drywall screws are unsuitable for materials with excessively thick tissues and poor strength. When the tightening force is too large, fine thread drywall screws easily slip.

Surface treatments of fine thread collated screw

fine thread collated screws

The surface treatment of fine thread drywall screws cannot be ignored. Now the surface treatment can be divided into two types, one is phosphorization and the other is galvanization. Their prominent role is to prevent rust and corrosion.

Phosphating fine thread drywall screws are essential, while blue-white zinc fine thread drywall screws are a supplement. The scope of the application and purchase price are basically the same. The slight difference is that black phosphating has a certain lubricity, and the tapping speed is slightly better. While blue-white zinc is better in antirust effect, and the color is light and not easy to be discolored after the paint decoration. There is almost no difference in antirust ability between blue-white and yellow zinc, only in usage habits or user preferences.
