Galvanized Phillips Slotted Dog Point Screw

 

Galvanized Phillips slotted dog point screws have become the first choice for occasions that require anti-loosening and tightening due to their unique design and reliable performance. The innovative tail design of the screw tail is its biggest highlight. The tapered end with a gradually narrowing diameter is combined with a special extruded thread, which will generate radial expansion force during the tightening process, so that the screw and the connector form an interference fit. Actual measurements have proved that this design can increase the anti-loosening torque by more than 40%. In the vibration test, it can withstand more than 2 million vibration cycles without loosening compared to ordinary screws.

The Phillips slot (Pozidriv) design of the screw head has been carefully optimized; the notch angle is precisely controlled at 45°, and the depth is perfectly matched with the standard PH2 bit. This design increases the tool contact area by 30%, greatly reducing the risk of slipping. Our comparative test shows that under the same torque, the transmission efficiency of the eleven-slot is 25% higher than that of the ordinary cross slot, which is particularly suitable for high-speed tightening operations on automated assembly lines. The surface galvanized layer adopts environmentally friendly blue-white zinc process, with an average thickness of 8-10μm. The salt spray test reaches the standard of 48 hours without rust, providing reliable anti-corrosion protection for the screws.

This galvanized Phillips slotted dog point screw performs particularly well in the fields of automotive parts, electrical equipment and outdoor facilities. In the application of automotive wiring harness fixing, its tail design can effectively resist high-frequency vibration in the engine compartment, solving the problem of traditional screws being easy to loosen. Electrical installation engineers especially appreciate its eleven-slot design, which ensures that the screw head can be firmly engaged even in a small space to avoid damage to the screw head.
