hexlox - The basics

The hexlox

The Hexlox is a small stainless steel insert that you place in the sockets of your already existing, magnetic (steel) hex bolts. Hexlox works with magnetic (steel) bolts. Test your bolt with a magnet from your fridge.

If your bolt is non-magnetic - or just slightly magnetic (like some stainless steel bolts) - swap the non-magnetic bolt for a magnetic (steel) bolt - we offer a great selection here.

By inserting the Hexlox into the bolt, using the Hexlox Key, you significantly increase the theft protection of this bolt.

Hexlox comes in 4, 5, 6, 8 and 10 mm.

You determine the right size Hexlox by inserting an Allen key/hex wrench into the hex bolt you want to secure. If a 5mm hex wrench fits - then you need a 5 mm Hexlox, and so on...

Your Hexlox can only be removed with your Hexlox Key.

If you lose your Key, simply order a new one from us, communicating your Hexlox Key Code, that identifies you as a previous customer. We take security very seriously and no one can order a Hexlox Key without providing a Hexlox Key Code - that our system can match to an order and email address.

How safe is Hexlox?

There is no lock in the world that is 100% safe.

All lock companies design and manufacture their products to combat opportunity theft, including Hexlox.

Most bike-part thefts are opportunity-driven. Someone passes a bike, sees that the saddle is not secured, and jumps on the opportunity to steal it.

Hexlox try to frustrate the thief so much that he/she simply gives up, and moves on. We believe we do a really good job at this.

The Hexlox key card & Key code

When you order from us, you will receive a Key card containing your Hexlox, your Key, together with your personal and secret Hexlox Key Code.

If you want to order more products and still only use your original key, simply communicate to us your Key Code. All new products will work seamlessly with your old key.

Hex bolts

A hex bolt has a socket with six sides (hexagon) and it tightens with an Allen key/hex wrench.

To determine the right size Hexlox simply insert an Allen key/hex wrench into the hex bolt you want to secure. If a 5mm hex wrench fits - then you need a 5 mm Hexlox, and so on...

Magnetic vs. Non-Magnetic bolts

Hexlox works with magnetic (steel) bolts. Test your bolt with a magnet from your fridge.

If your bolt is non-magnetic - or just slightly magnetic (like some stainless steel bolts) - we recommend you to swap the non-magnetic bolt for a magnetic (steel) bolt - we offer a great selection here.

If you want to keep your non-magnetic bolt, simply get the Hexlox Magnetic Insert

Cylindrical head vs. Pan head (rounded head)

If your hex bolt (with cylindrical head) is exposed and not sitting recessed, the bolt head could be grabbed and loosened with pliers - which makes this bolt still vulnerable to theft - even with a Hexlox installed.

Check this and replace your exposed bolt with our Hexlox Ready pan head bolt (with a rounded head - where pliers simply slip off) if necessary.

How to measure bolts

You need to know 3 things about your bolt:

Length (in mm)
Diameter (in mm)
Size socket (M5, M6 etc.)

Measure bolt lenght

Measure the length of the bolt from the inside of the head to the end.

Measure bolt diameter

Measure the diameter of the bolt body - not the head!

Measure bolt socket

Measure the size of the socket. This is the size hex tool that can fasten and unfasten the bolt in mm. (It's also the size Hexlox that will fit into this particular bolt.)
