Ferrol Pins / Studs

About our ferrol pins and studs

Driv-Lok Ferrol pins and studs have raised ferrol rings around the entire circumference of the pin. These rings are set at an angle that allows the pin to be inserted from one direction but not removed from the opposite direction, offering an aggressive locking force. The crests of the ferrol rings constitute the expanded diameter and are measured with ring gauges.

Driv-Lok Ferrol Pins and Studs can be made from Low-Carbon, Aluminum, and Stainless Steel and typically come with a plain rust-preventative coating, zinc plating, or passivation treatment. However, we can also offer other finishes upon request.

Typical applications for ferrol pins and studs

Driv-Lok Ferrol Pins and Studs can be inserted in all plastic assemblies and some soft metals or extrusions. They are ideal for long-term positive locking of components and excellent for tamper-resistant applications. The design of the final application will determine which type of Driv-Lok Ferrol Pin or Stud should be used.
