Installation and Use of Products
The self tightening bolt adopts a proven self tightening design, and the product is permanently installed into a pre punched or drilled installation hole thin plate through pressure.
Punch or drill corresponding installation holes on the installation plate. Secondary processing such as deburring is not allowed.
2. As shown in the figure, thread the fastener through the installation hole and place it in the lower mold.
3. When the upper and lower molds are parallel, apply extrusion pressure to rivet the bolts into the plate. After installation, the bolt head plane should be flush with the installation plate surface.
