What are spool pins in a lock?

SPOOL PINS are security pins that make lock picking more difficult. To pick them, you need to be better. It’s great being better.

How do I choose a spool pin?

Picking a Spool Pin The answer is quite simple. All we have to do is very slightly lighten up on the pressure applied to the tension wrench and begin very gently pushing on the spool pin. As you push on the spool you will experience counter-rotation – this is good and means you are doing it right.

Which spool holder do I use?

Do you find your thread catching on the sewing machine? Generally speaking stacked thread should be placed on a vertical spool pin on the sewing machine. The thread should leave the spool at a RIGHT angle, in line with the direction of the wound thread.

How do I stop Oversetting pins?

The best way to avoid an overset pin is to ensure that you are not forcing things. Instead, gently probe for a binding pin and then even more gently lift that binding pin until you get the indicators that the pin is truly set.

What is the best security PIN for locks?

First developed in 1865 by Linus Yale Jr. (founder of the Yale Lock Company), the spool pin – due to the simplicity of its design and the ease of manufacturing it – is the most commonly used security pin in locks today. But with this simplicity comes a cost. As we will soon see, the spool pin is not as sneaky as it tries to be.

What is the difference between a spool pin and a pin?

Spool Pin Acquiring its name from its seen resemblance to a spool, the infamous spool pin has the same diameter as a standard pin on both its top and bottom segments, however, it has a wide horizontal serration making it narrower along its midsection.

How do I know if I am stuck on a spool pin?

There is an additional step to verifying that you are in fact stuck on a spool pin. While maintaining light tension on the plug, apply a more than usual upward force on the pin. If you are indeed caught on a spool pin, the bottom ridge of the pin will slightly push back against the plug as you place pressure on the pin.

When was the pin tumbler lock invented?

In 1865, Linus Yale Jr. (inventor of the modern pin tumbler lock) took the first step in solving this problem by slicing a notch into the driver pins (Patent US48475). This simple modification would cause the driver pins to “catch” at the shear line if the plug was lifted under tension.
