Liberty Fastener Security Fasteners

Security fasteners are any kind of fastener—usually in the form of a screw—that is virtually impossible to remove without a special removing driver. Security fasteners are an important part of our distribution for our customers that cannot afford to make products that could somehow be tampered with.

Liberty Fastener security fasteners come in a large selection of sizes, shapes, models and finishes so that no matter what kind of job you are doing, one of them will work well for you.

Why Would I Need a Security Fastener?

Why do you need a security fastener? The answer to this question is different for everyone. Here are a couple reasons why you may want to consider using security fasteners:

  • On street signs and other important permanent safety signs

  • Electrical panels that are not meant to be removed

  • Any kind of panel or mechanism that guards important or confidential materials

  • Medical devices

  • Heavy machinery, automotive or aerospace applications

In almost all of these scenarios, a security fastener would prevent tampering and/or removal which could have serious consequences.

Types of Security Fasteners

Liberty Fastener provides security fasteners in various models. There are screws with oddly shaped heads or heads that can't be removed with a standard wrench or screwdriver. Most security fasteners can only be removed with a special wrench that is unique to the fasteners themselves.
