Product and application brief
Roofing screw enquiries should identify the screw and sealing-washer assembly, together with the roof sheet, support and environmental requirements.
For metal roofing or cladding, provide the project fastener specification, profile details and substrate. Identify whether EPDM is required rather than assuming every sealing washer uses the same material.
Specification checklist for quotation
The table defines the information to send, not a guaranteed stock range or a substitute for an approved technical specification.
| Requirement | What to specify |
|---|---|
| Roof assembly | Sheet profile, material stack and supporting member |
| Screw dimensions | Diameter, length and thread / drill-point requirements |
| Washer | Diameter, backing material and specified seal material |
| Material / finish | Screw construction, coating and exposure requirements |
| Appearance | Head colour or finish if required by the project |
| Documents | Roof-system requirements, tests, quantity and packing |
Selection and compatibility
For metal connections without a sealing requirement, review the hex head screw range. For a specified stainless construction, identify the body and drill-point materials in the same brief.
A sealing washer does not independently guarantee a weather-tight roof. The selected screw / washer assembly, roof detail and prescribed installation must be suitable for the system.
Prepare the order brief
Send a controlled drawing or complete product reference, plus quantities by size. Identify the inspection reports, packaging and shipping requirements needed for your order. If a requirement is not settled, mark it as needing confirmation rather than assuming a substitute.
Read the self-drilling screws enquiry checklist before submitting your parts list.
Can I request EPDM washer screws?
Yes. State EPDM as a requirement and include washer dimensions, screw geometry, substrate and project documents. The final screw and washer specification is confirmed in the quotation.
