Securing bike racks with Kinmar Security Nuts

There are effectively three main types of security nuts in Security Safety Products’ range: Shear nuts, Kinmar permanent nuts/removable nuts and Scroll nuts. Increasingly, security professionals and novices alike are being drawn towards the many benefits of Kinmar security nuts.

Arguably, there are three key reasons for this:

1. The Kinmar is available as either a one-way permanent fixing or a two-way removable nut (unlike traditional shear nuts, which are only available as a permanent fixing).
2. With its own driver socket and superior torque value, against the Shear nut, the Kinmar also gives the operator far greater control over how far this security fixing is tightened
3. Whilst the Kinmar removable security nut does the same job as a scroll nut, invariably the nuts and socket are far more cost effective.

To ensure the Kinmar remains as an exclusive security fixing, at Security Safety Products we have taken the decision to only ever sell the Kinmar removable nut socket to individuals and businesses that either buy the nuts at the same time or to those who have bought Kinmar security fixings from us previously. This means we will never knowingly sell the Kinmar tool to people who may have the ambition to remove someone else’s Kinmar removable security nuts for more sinister reasons.

One customer of ours, Jon Anderson, felt the Kinmar security nuts were the ideal solution to ensure his mobile home’s bike rack remained attached.

Jon rightly takes the view that a security system is only as good as its weakest link. On the rear of his camper van he has a tough wearing rack made from galvanised steel. When he puts his £350 bikes on this rack, he double locks them in place with top of the range bike locks.

However, Jon recognised that a thief’s point of attack would probably be the standard nuts supplied with this product. Essentially these could simply be removed using a standard spanner.

By replacing the standard nuts with Kinmar removable security nuts in the way shown (picture right), Jon has been able to significantly reduce the chance of his bike rack being targeted by thieves.

As a cautionary footnote to this story, Jon mistakenly ordered M10 nuts the first time round believing the 10mm measurement related to the external measurements of the existing nut, rather than the size of the hole. In the end Jon ended up using M6 Kinmar nuts to go on the bolt’s 6mm wide thread.
