Is There Such Thing As A Thief-proof Fastener?

DIY Questions and Answer January 5, 2016 Sonia

Q: Thieves stole our bicycles by unscrewing the toggle bolt of the bike rack, and stealing the entire rack to which the bikes were chained. Is there such thing as a thief-proof fastener?

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.
