Securing Your Bike

DIY Questions and Answer June 10, 2015 Sonia



Q: Our bikes where chained to a bike rack that was mounted to the wall of our back porch. Thieves still stole the bikes by unscrewing the toggle bolt that held the rack to the wall. Is there such thing as a thief-proof bolt?

A: There are security fasteners on the market that require special keys to install and remove. These screws, nuts and bolts require specially shaped drivers to turn them—tools which thieves don’t usually have at their disposal. Some security fasteners are so unique that the keys are only available from the fastener manufacturer. Another option is to reinstall a standard toggle bolt, and then use a grinder to distort the shape of its head so a thief won’t be able to grip it with a wrench or screwdriver.
