Questions we get asked about this item
Why a hex washer head instead of a Phillips?
A hex head cannot cam out. On a roof, where the driver is often held at arm's length above the head, that alone removes most stripped fixings and keeps the washer seated flat.
Can you match our roof sheet colour?
The head is colour coated and different colours are available — send the colour reference with the enquiry. The washer can be supplied bonded, as steel plus EPDM, as PVC or as plain rubber, in 14mm, 16mm or 19mm outside diameter.
