Custom Hinge Pin Terminology

With more than 30 years’ of experience making custom hinges with OEM’s, we understand that the hinge pin material type and diameter is integral to your specific application.


Often, the hinge pin is given little consideration. While it’s common to use similar material types, there are often good reasons for mixing materials. For example, your steel hinge may perform better with a brass pin or an aluminum hinge may require a stainless-steel pin. Another factor that is often overlooked is how the hinge pin is retained within the hinge barrel.


Midlake gives you more options to manufacture the custom hinge that works best for your application.

Pin spun on both end is non-removable. Pin spun on one end pin remains removable. Most common on butt hinges.

Staked Pin

Staked Pin

Crimped Ends

Crimped Ends

Non-removable pin. Knuckle is depressed, confining pin.

Pin is removable. This style is often used for “quick release” applications.

Midlake features an in-house CNC machining department. This gives us great flexibility when manufacturing hinge pins. Features such as grooves, through holes, bushings, and knurled pins can be manufactured in house.


Midlake has experience manufacturing hinges utilizing spring coil pins as well. Spring coil pins are used to manufacture friction hinges.
