A common screw sleeve (also known as a thread bushing, thread sheath, or thread insert) is a metal or plastic device used to reinforce or repair a screw hole.
They are widely used in a variety of industries, including aerospace, automobile manufacturing, electronic equipment, furniture making and other fields.
Main feature
1. Strengthen the screw hole: the screw sleeve can improve the strength of the screw hole, especially in soft materials (such as wood, plastic, aluminum alloy, etc.), to prevent the screw hole from being damaged by repeated disassembly.
2.Repair the damaged screw hole: When the screw hole is damaged or worn, the screw sleeve can be used to repair and restore the function of the screw connection.
3. Provide better fixing: the screw sleeve can provide a more accurate thread fit, making the screw connection more solid and reliable.
4. Corrosion resistance: usually made of stainless steel or other corrosion-resistant materials, suitable for wet or dusty environments.
