Self-tapping sleeve installation instructions

The self-tapping sleeve is a fastener product with internal and external bolts and cutting holes, often used in soft materials such as aluminum alloy, cast iron, plastic, and copper to effectively form a robust inner thread hole. Stainless Steel Screw-Locking Helical Inserts for Particle-Free Environments. Made of Nitronic 60 stainless steel, these inserts prevent the screw from binding or sticking without any coating or lubricant that could contaminate particle-free environments. Once the screw is installed, a distorted thread grips the screw to resist loosening. Also known as Heli-Coil inserts, they have coils that expand once installed to anchor the insert securely. All have a prong for ease of installation. An installation tool grips the prong and reduces the coil diameter, enabling the insert to fit in tapped holes. Remove the prong to insert the screw. Installation requires a drill bit, a helical insert tap, an installation tool, and a prong break-off tool.

Self-tapping screw sleeve products are widely used in the automotive industry, and they are used in network equipment, household appliances, military equipment, and factories.

The self-tapping screw sleeve product can be used for multiple maintenance and disassembly work on soft materials to meet some conditions that require frequent disassembly. At the same time, the product's structure is simple, and the later installation period is relatively simple to improve the installation efficiency of the product.

In addition, the self-tapping screw sleeve products can also withstand higher loads during use so that they can meet some industries with high requirements for robustness.

1. Preparation before installation: The self-tapping screw sleeve can be installed manually or mechanically. A suitable lubricant is recommended for pre-lubrication before installation. For example, cutting fluid, alcohol, or kerosene can lubricate unquenched medium and hard light metals. Use a 5% to 8% cutting fluid for ductile soft metals and cast iron.

2. A small amount of installation: when the number of installations is small, you can take the simple installation method, that is, take the corresponding specification bolt and nut method, fix the self-tapping screw sleeve on the corresponding type of bolt, fix the nut of the same kind, so that the three become a whole, and then use the wrench to screw the self-tapping screw sleeve into the bottom hole, and then pull the bolt out.

3. Batch installation: Special mechanical tools can be used when the number of installations is significant. First of all, install the self-tapping screw sleeve on the unique tool, and then screw the tool equipped with the self-tapping screw sleeve into the preset hole for about one circle, ensure that the tool and the prefabricated hole end face is vertical, and then slowly screw the self-tapping screw sleeve into, when the self-tapping screw sleeve end face is lower than the prefabricated hole end face about 0.2mm, stop screwing and reverse the unique tool out. The end of the self-tapping screw sleeve installation tool has a hexagonal head, which can be manually connected with electric or pneumatic tools.
