Slotted Capstan Screws DIN 404
Our range of Slotted Capstan Screws DIN 404 are specialist fasteners designed for applications requiring secure fastening, precise adjustment and alternative tightening methods. Manufactured to DIN 404 standards, these screws feature a cylindrical head with a traditional slotted drive and cross-drilled holes, allowing them to be tightened or loosened using either a flathead screwdriver or a suitable pin or bar inserted through the head.
What are Slotted Capstan Screws?
Slotted Capstan Screws, also known as Tommy Screws or Ammeter Screws, are machine screws featuring a distinctive raised cylindrical head with radial holes. These holes allow a pin or sliding bar to be inserted for tightening or loosening, making them particularly useful in applications where access to the top of the screw is restricted.
The cross-drilled holes can also accommodate locking or securing wire, helping to prevent unwanted loosening in applications where additional security is required.

Electrical Engineering: Used for securing and adjusting components in electrical equipment and assemblies.

Mechanical Engineering: Suitable for fastening and adjustment mechanisms in machinery and equipment.
-
Instrumentation: Ideal for precision instruments and equipment requiring controlled adjustments.
