How to Remove a Coiled Spring Pin

One of the key advantages of Coiled Spring Pins is their ability to be removed from an assembly without causing damage to the hole—when done correctly. These serviceable pins make maintenance and repair easier than other press-fit fasteners, saving both time and cost. This instructional video illustrates how to properly remove Coiled Pins from through holes and blind holes.

00:00:08 I’m Jeff Greenwood, Pin Product Sales Engineer at SPIROL International. Today we’re at our Connecticut manufacturing facility in our quality lab. We're going to be going through how to remove a Coiled Spring Pin. Coiled Spring Pins are serviceable fasteners, which provides a lot of advantages for designers. And there’s really two different scenarios where you're removing the Coiled Spring Pin from an Assembly. The first is with a through hole. In this scenario you want to grab a punch, which has a square flat end

00:00:39 and is slightly smaller in diameter than the hole. It's important that it's just slightly smaller than the diameter and captures all the outer coils of the coil pin because if the punch is too small it telescopes the coil pin. If the punch is too large it plows through material in the assembly. So grab your punch, align it in the assembly, and grab a hammer or a press and advance the pin until it gets removed from the assembly. The other scenario is a blind hole

00:01:09 where the hole does not protrude through the entire assembly. There's a few different ways that you can approach removing the coil pin in this scenario. One of the most common is to grab a pair of pliers and make sure that in the design you set it up so that the pin is protruding from the assembly. An operator can come through here, grab pliers, and remove the coiled spring pin from the blind assembly. Thank you for watching our video!
