Douwes International BV has been Europe’s market leader in SecuFast® security screws for over 15 years. We have recently added a new security screw to our range: Non – Recess TRF®.
The SecuFast® Non – Recess TRF® is a shear bolt that can be fastened with a normal cross recess driver. Once a certain torque is reached, the hexagon head brakes of and removal of the screw is impossible.
Non – Recess TRF® are available in machine screws M3, M4, M5 and M6 in stainless steel, lengths from 6 – 25 mm.
