شرح المواد والصف
Blue zinc plated self tapping screws are commonly made from carbon steel or 10B21 when case hardening and thread-forming performance are required. Low carbon steel can be suitable for lighter applications, while boron-treated steel can be reviewed for stronger tapping performance after heat treatment.
Buyers should confirm whether the screw needs surface hardness, core hardness, case depth, torsion performance, or a specific material grade. If the screw will be installed with an automated driver, include bit type, torque range, pilot hole size, and mating material in the inquiry.
دليل اختيار تشطيب السطح
- Blue zinc plated: common blue-white zinc finish for clean appearance and general indoor corrosion protection.
- Trivalent zinc: often requested for controlled environmental and customer-specific requirements.
- Clear zinc: selected when a silver tone is preferred for visible hardware.
- أكسيد أسود: suitable for indoor equipment screws where dark appearance and oil protection are acceptable.
- Phosphate: selected for oil retention, friction control, or paint adhesion applications.
- Zinc nickel: considered when higher corrosion performance is required for automotive or equipment applications.
