What is the tolerance range of precision screws?
At present, in the process of injection molding, stamping, testing, etc., the product is usually positioned on the mounting plate or the positioning plate by pins. The general pin positioning method uses cylindrical pins with the same cross-sectional diameter for positioning. Because the product is easily deformed during processing, the pin positioning hole on the product is also deformed. With this kind of pin for positioning, the pin is often stuck. Dead products cause inconvenience in handling the workpiece, resulting in broken pins or scratched or even damaged products, with obvious defects.

In the modern industrial field, products such as nuts and bolts are widely used to lock structural parts, but at the same time we also find that in many cases, especially when applied to vibration, we often need to lock the already locked Structural parts are regularly repaired and strengthened to prevent structural dislocation caused by loose nuts and bolts.
Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with an external thread), which needs to be matched with a nut to fasten and connect two parts with through holes. This form of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
