M3-M16 Type 307 / 308 Self Tapping With 3 Cutting Holes For Battery Pack

Introduction

• The inside and outside of the self-tapping screw sleeve has tooth grain, embedded in plastic, aluminum alloy, cast iron, copper and other soft materials, can form a higher strength of the internal thread hole, self-tapping screw sleeve can also repair the damaged internal thread.
• 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

For difficult to cut materials, it has larger wall thickness, shallower but sharper external thread. The screw sleeve uses three round holes as cutting edge. The difference between 307 and 308 is the length of the insert.
