DW-G1 Through Hardened Screw with Super Wearing and Corrosion Resistance
Â
Â
We use imported or local made tool steel materials for Through Hardened Screws, including DW-G1, DW-G2, DW-G3 ... DW-G8. After series of quench & annealing processes, to achieve high toughness & hardness, they are especially suitable for high wearing materials and production processing.
Â
The most significant features of through hardened screws is their ability to resist corrosion and wear, which is essential for maintaining the integrity of structures and equipment. These screws are also highly resistant to fatigue and have a longer lifespan than regular screws.
