Security Bolt Fixings

Leo Industries manufactures security bolt fixings engineered to prevent tampering, theft, and unauthorized dismantling in demanding environments. Security bolts and anti-vandal fasteners use special drive profiles or controlled shear mechanisms that make removal difficult using common tools. These fixings are widely preferred for public infrastructure, utilities, industrial equipment, and outdoor installations where long-term reliability and safety are critical. With consistent machining, dependable materials, and strict dimensional control, our security bolt fixings support stable clamping force and reliable joint performance across a wide range of applications.

Working Principle & Process Flow

Security bolt fixings work by using a tamper-resistant head design that restricts removal or loosening. In many designs, a one-way drive allows tightening but resists reverse rotation, while other variants use a proprietary recess that requires a matching driver bit. Shear-type security bolts include a breakaway section that snaps at a preset torque during installation, leaving a smooth, non-grippable head that discourages tampering. The installation process typically involves aligning the joint, selecting the correct fastener size, tightening to the recommended torque, and completing a final visual check for correct seating and engagement.
