• Self-tapping screw sleeve has self-tapping capability, so the base material need not be tapped in advance to save cost.
• Large contact surface with finished products, strong tensile strength, lower strength materials can be used in product design.
• For the female thread that has worn out or broken teeth, use the self-tapping screw sleeve to continue to use the same screw.
• Strong resistance to vibration, can prevent looseness.
• There is no clearance with the base material, and the base material has good air tightness if it contains bubbles.
• Self-tapping screw sleeve installation is simple and rapid, only one assembly tool, low cost, almost no defect rate.
• The tapping screw sleeve is generally made of carbon steel and stainless steel. Carbon steel can be plated with colored zinc, yellow zinc, blue and white zinc.

Parameter
