A stopper bolt is a bolt designed for positioning parts and machines. It acts as a stopper for moving components and it is engineered to improve positioning accuracy to mitigate the impact of contact by bringing the bolt's head or the end of the threaded part into contact with an object. Commonly used with a nut or lock nut to secure the position, stopper bolts ensure precise adjustments and reliable fixation.
Stopper bolts serve dual functions as stoppers and positioning elements, allowing for fine adjustment of setting positions in various applications.
They secure machine parts or devices in specified positions, maintaining alignment through direct contact.
Stopper bolts facilitate precise positioning during the replacement or adjustment of jigs and tools, reducing errors and ensuring accuracy.
Used as adjustable stoppers for moving parts of machinery, they control the range of motion, often in conjunction with shock absorbers for enhanced precision and safety.
As mechanical stoppers, they limit the movement of machinery parts, preventing accidents and damage in case of abnormal operation.
The principle revolves around adjustable positioning using the threaded section and secure fixation with a nut. Materials like carbon steel, chromoly steel, and stainless steel provide durability and wear resistance, with some bolts featuring protective resin to prevent damage to contact surfaces.
Features a hexagon bolt head as the contact surface, offering stable positioning due to a wider contact area.
Utilizes the bolt end as the contact surface and it is available in shapes like hexagonal bolts and hexagon socket head bolts.
Resembles a hexagon socket set screw, with a hardened, flat, surface-finished end serving as the contact point.
Equipped with protective resin or rubber at the contact part to prevent material damage, absorb shock, and reduce noise.
While similar to adjustment screws and positioning bolts, stopper bolts are distinguished by their primary function of fixation, typically featuring coarser threads and standard thread accuracy, making them suitable for different applications based on specific needs.
