Nuts & Washers
Washers
Washers — spring washers for vibration, EPDM bonded washers for sealed roof penetrations, and moulded caps to cover the driven head.
What this group is for
Three different jobs get called 'washer' on a roof: spreading load, sealing a hole, and hiding the fixing. They are separate items and they are normally used together.
- Spring washers keep residual load on the thread as a joint settles
- EPDM bonded washers in 14mm, 16mm and 19mm outside diameter
- EPDM chosen for UV and ozone resistance
- Moulded caps fitted over the driven head, colour matched
