How Do Cam Locks Work: Understanding the Basic Mechanisms

Cam locks are commonly used in a variety of applications, including cabinets, lockers, mailboxes, and even automobiles. But have you ever wondered how they work? In this article, we will dive into the basic mechanisms of cam locks and explain their functionality.

What is a Cam Lock?

A cam lock is a type of locking device that consists of a cylindrical body with a protruding cam. The cam has a keyhole in the center that allows the user to insert a key and turn it to lock or unlock the mechanism. The body of the lock is typically made of brass or steel, and the cam is made of hardened steel.

The Basic Mechanisms

The cam lock works on a simple mechanism that involves a cam and a locking bar. The cam is connected to the key and turns when the key is inserted and rotated. As the cam turns, it moves the locking bar in or out of the locking mechanism.

When the lock is in the unlocked position, the locking bar is pulled back, and the cam is in a neutral position. When the key is turned to lock the mechanism, the cam rotates and moves the locking bar forward into the locking mechanism. The locking mechanism is typically a hole or a slot where the locking bar fits snugly.

Types of Cam Locks

There are several types of cam locks, each with its own specific application. These include:

  • Tubular cam locks - commonly used in applications such as vending machines and gaming machines.
  • Flat cam locks - commonly used in cabinets, drawers, and mailboxes.
  • Radial pin tumbler cam locks - commonly used in automobiles and other vehicles.
  • Screw cam locks - designed for use with furniture and other removable fixtures.


Cam locks are a reliable and secure locking solution that is widely used in a variety of applications. Understanding their basic mechanism can help you make an informed decision when choosing a lock for your specific needs. Whether you need a lock for a cabinet, locker, or automobile, there is a cam lock out there that is perfect for your needs.
