Resistorx Security Screws

Resistorx Security screws for wood frames which work with picture plates having 4.5mm holes. The 6 lobes with the central pin mean that the screws can only be inserted and removed with the matching driver bit. Often known as Resistorx screws. 

Precision made in UK using A2 stainless steel with a self-tapping thread so can be used with most suitable wall plugs.
