This pig nosed self-tapping security screw is suitable for low to medium torque applications and is a reusable fixing, ideal for applications where maintenance is required.
They are typically found within the electrical trade, as they are ideal for use in prisons, hospitals, mental health facilities, schools, lifts, trains and other public areas.
An economic solution, these anti-tamper screws host an aesthetically pleasing appearance and are installed and removed using a special insert bit.
The two holes can be drilled at different distances between centres, so it is advisable to purchase the screws and corresponding bits/drivers from the same supplier.
2-hole screws are more prone to cam-out than other security screws such as Pin Hex security screws. Users should also be aware that when tightening the screw the drive bits are prone to bending or breaking after prolonged use, so we recommend purchasing additional drive bits as a back up.
