Pitlock M5 Nut

(2 customer reviews)

From: $12.99

This is an M5 coded nut, which can be used as a replacement for your existing Pitlock locking mechanism. This is only intended for quick release skewers, and will not fit solid axles.

Pitlock nuts only come in silver, but Pitlock kaps can be purchased to keep out debris and provide a sleek look.

See below for additional product and sizing specifications.

Please provide your Pitlock keycode here:

SKU: PNCCM00 Category:


This is a replacement Pitlock nut for quick release skewers. If you need to replace a solid axle nut, they can be found here.

This is the most critical piece of any Pitlock locking mechanism. There are hundreds of different shapes to the Pitlock coded nuts, so the likelihood of a thief having a key that will fit your nut is next to zero.

Note that this is not a complete locking mechanism, only the coded nut. For a complete locking mechanism setup, you will also need to order the lock housing, a compression washer (either for a seat post skewer or a wheel skewer), a teflon ring and a lock ring.

    Works as advertized.

    If you have multiple bikes that need front-wheel security, this is the ONLY way to go. I bought a set years ago and recently added a few more bikes to the stable. I kept my card with the code key and all these years later was able to order a few more locking nuts and a few more keys. Plus I got an accessory you can insert to turn the key instead of using an allen wrench. I can keep it on my keychain, which is nice, but even better the key ring prevents the rod from slipping out of the key. Thoughtful and nicely executed. They shipped right away and everything worked perfectly. Could not have been happier with the entire experience.
