Din 69872 Pull Studs: An Essential Component for Machine Tools

The pull stud, also known as a retention knob, is an essential component of a machine tool. It is used to connect the spindle of a machine tool to the tool holder, allowing the tool holder to be locked into position. The pull stud is a threaded fastener with a head on one end and a threaded shank on the other end. The head has a hexagonal or square recess to accept a wrench. The threaded shank is used to attach the pull stud to the machine tool’s spindle.

Din 69872 pull studs are one of the most popular types of pull studs used in the machining industry. This type of pull stud is manufactured to the German DIN 69872 standard. Din 69872 pull studs are designed to provide superior holding power and reliability when used in a variety of machine tools. The pull stud is made from high grade alloy steel and is hardened for maximum durability and strength.

The pull stud is a critical component of a machine tool since it is responsible for securely holding the tool holder in place. The correct pull stud must be selected based on the application and the tool holder being used. The pull stud must also be properly installed to ensure that it provides the necessary holding power.

In order to ensure that the pull stud is properly installed, it is important to inspect the pull stud and the spindle for any signs of wear or damage. Site is also important to ensure that the pull stud is the correct size and thread type for the application. Once the pull stud is properly installed, it is important to periodically inspect it for signs of wear or damage.

Din 69872 pull studs are precision components that are designed to provide reliable service in a variety of machine tools. They are made from high grade alloy steel and are hardened for maximum durability and strength. When properly installed and maintained, they can provide reliable service for many years.

In addition to providing reliable holding power, Din 69872 pull studs can also be used to reduce vibration and improve the accuracy of the machining process. When used in combination with other elements, such as a tool holder, the pull stud can help reduce chatter and improve the quality of the machined parts.

Overall, Din 69872 pull studs are an essential component of a machine tool and are designed to provide superior holding power and reliability. They are made from high grade alloy steel and are hardened for maximum durability and strength. When properly installed and maintained, they can provide reliable service for many years.



Din 69872 Pull Studs are a type of fastener used in CNC machines for quick and secure mounting and removal of tools. They are also known as ‘captive’ or ‘clamp’ studs due to their ability to hold a tool in place during machining operations, without the need for additional nuts, bolts, or screws.

Din 69872 Pull Studs are typically made from high-grade steel and are designed to fit certain machine tool spindles and collets. Each stud is designed with a specific thread size and length, allowing for a secure fit and easy installation. The studs feature a ‘pull’ feature, which allows for quick and easy removal, without the need for additional tools or hardware.

The Din 69872 Pull Studs are designed to be used with CNC machine tools such as lathes, mills, grinders, and routers. The studs are installed into the machine spindle and serve as a mounting point for the tool. This allows the tool to be securely held in place while the machine is in operation, reducing the risk of tool movement or damage.

The Din 69872 Pull Studs also have several advantages over traditional tool mounting methods. For example, they are much easier to install and remove than other methods such as nuts and bolts. This means that tools can be changed more quickly and efficiently, reducing downtime and increasing productivity.

In addition, the Din 69872 Pull Studs are designed to be highly durable and robust. The studs feature a corrosion-resistant coating, making them ideal for use in harsh and corrosive environments. Additionally, the studs are designed to withstand high levels of vibration, shock, and torque, ensuring that they remain secure even in extreme conditions.

Overall, Din 69872 Pull Studs are an essential component of any CNC machine. They provide a secure and reliable mounting point for tools, allowing for quick and easy installation and removal. The studs are highly durable and long-lasting, making them ideal for use in a range of industrial environments. If you are looking for a reliable and secure tool mounting solution, then Din 69872 Pull Studs are a great choice.
