## Summary

Fastener selection depends on the whole exposure and material combination. A generic stainless-steel description does not resolve every coastal or chemically exposed connection.

## Practical method

State whether the installation faces salt spray, cleaning chemicals, pool splash or persistent wetness. Ask the responsible designer and supplier to specify suitable fixings and address contact between dissimilar metals. Keep product codes rather than relying on an installer calling all screws stainless. For a waterfront repair, inspect the supporting connection as well as visible screw heads. Do not infer the concealed fixing's condition from an intact board surface. Record what was installed so replacements can use a compatible specification.

## Planning and verification

Compare complete systems for the stated use, including supporting structure, connections, drainage and maintenance access. Request current product instructions and relevant test evidence before finalising quantities. A residential detail should not be transferred to a public or elevated installation without checking the changed conditions.

## Handover and maintenance

Record the selected profile, batch, approved drawings and maintenance owner. Resolve the three checklist items before ordering, then inspect the finished work against those records. Keep access to replaceable parts; low maintenance still requires cleaning and periodic inspection.

## Key points

Exposure description
Metal compatibility
Recorded fixing grade

## Comparison

Design check | Evidence to record
Exposure description | Show the requirement on the project drawing
Metal compatibility | Obtain applicable product or design evidence
Recorded fixing grade | Assign installation and maintenance responsibility

## Choosing corrosion-resistant decking fasteners — What should be confirmed before ordering?

Fastener selection depends on the whole exposure and material combination. A generic stainless-steel description does not resolve every coastal or chemically exposed connection. Confirm the three project checks below with the supplier and the responsible designer. A sample establishes appearance, not approval of the complete installation. Exposure description; Metal compatibility; Recorded fixing grade
