The tamperproof "System Zero" Screw

System Zero Screw The screw illustrated is a hardened self tapping type that has a thread length of 6 mm.

As far as beekeeping goes this type of screw has been used by me for the fitting of  8 way bee escapes  to 6 mm thick plywood. They are very easy to use as they fit the special driving bits very well.

The incorporated flange spreads the load when used to attach plastic components.

I use an electric screwdriver to insert these, the driving bit holds them perpendicular to the work which makes the process speedy and accurate.

Some websites will provide dimensional data.
