DIN 99 Tapered Clamping Lever

DIN 99 is a manufacturing standard for the tapered clamping lever. It consists of a solid metal core fitted with a bore, either internally threaded or unthreaded. The core has an eyelet end designed for mounting on a cylindrical base. Mounting on the shaft can be fixed with adhesive, or the lever can be installed using the thread.

Under this standard the lever can be made in 4 versions: the shape of the lever can be straight or angled, with the angled version set at 20 degrees. The shapes also differ depending on the bore type.

Manufacturing features of the product

Malleable cast iron or carbon steel can be used to manufacture the tapered clamping lever; the product is made with or without a protective coating. If it is intended for use in high humidity or chemically aggressive environments, the metal is given a thin zinc coating. Galvanizing prevents adverse effects and keeps the metal from corroding. For maximum protection reliability, levers can be fitted with a thick passivating layer.

Stainless steel A2 and A4 can also be used for manufacturing to the standard. This is an acid-resistant material that is not subject to corrosion and is resistant to various aggressive factors. Stainless steel levers are designed for long-term use in chemically aggressive environments.

Technical specifications of the product

The product is manufactured to the standard in accordance with the following technical parameters:

• The overall length of the product in the straight version can range from 50 to 200 mm.
• The length of the lever in the angled version can be from 48 to 190 mm.
• The nominal thread diameter of the bore varies from M6 to M24.
• The rise height of the lever for products in the angled version can be from 24 to 97 mm.

This type of fastener is supplied in a wide range of sizes – you can select the most suitable option for your task.

Application options and ordering conditions

This type of product is widely used in machine building. It is designed for loosening and tightening, and its length allows the lever to be used as a lever arm to achieve high tightening force. This has given it wide application possibilities in the assembly of various units and equipment. It is used in machine tool building, production of special equipment, and many other industries.
