Product and application brief
Identify the screw, washer and contacted surface as one arrangement. Include washer inside and outside diameters, metal backing and seal requirements. A roof or cladding application must follow the selected system’s approved installation conditions.
Specification checklist for quotation
These are the inputs needed to review an enquiry, not a guaranteed stock range or a substitute for an approved specification.
| Requirement | What to specify |
|---|---|
| Mating screw | Product reference and shank / thread dimensions |
| Washer geometry | Inside / outside diameters, backing and sealing-layer dimensions |
| Backing | Required metal and finish |
| Seal | Specified EPDM requirement and any required test evidence |
| Service | Intended exposure and selected assembly requirements |
| Order | Quantity, supplied loose or assembled, packing and destination |
Selection and compatibility
A bonded sealing washer serves a different role from a plain flat washer. Matching outside diameter alone does not confirm the same sealing arrangement.
No universal tightening torque, weatherproof rating or service-life claim is made here. Confirm installation and acceptance requirements for the complete selected product, not the washer photograph alone.
Can I order sealing washers separately from screws?
You may enquire about separate washers. Provide the actual mating screw and washer requirements so geometry, fit and quotation scope can be reviewed.
Prepare your order brief
Attach a controlled drawing or complete product reference and list quantities by size. Define the required inspection, packaging and delivery destination. Mark unresolved details for confirmation instead of assuming a substitute. We review availability, finish, MOQ and production timing against the actual enquiry before the order is agreed.
