2-Hole Truss Head Security Self Tapping Screws
2-Hole Truss Head Security Screws have two holes drilled into the head, which led to them also being known as Pig Nose or Snake Eye screws. They require a special insert bit for installation and removal.
The two holes can be drilled at different distances (between centres), therefore it is advisable to purchase the corresponding bits from the same supplier as the screws.
Suitable for low to medium torque applications, these reusable fixings have a low profile domed head and are difficult to remove without the special tool.
2-Hole Truss Head Security Screws are an ideal fastener for applications where maintenance is required, as the two-pin drive is designed to offer some security and also help in maintaining the aesthetics of the application it is used in. They may be more prone to cam-out than other security screws such as Pin Hex Security Screws.
They are suitable for use in areas where aesthetics are more important than security, such as trains or public lifts.
