Application

Choose the right fastener by application—roofing, cladding, steel frames, timber purlins, concrete/masonry, boards, skylights and fibre cement sheets—supported by clear installation and washer-setting guidance.

Every site condition is different—substrate thickness, profile type, exposure, and build method all affect fastener performance. This page helps you quickly map common construction scenarios to the right fastening application categories, so you can specify with confidence and reduce on-site issues like leaks, overdriving, sheet deformation, or poor pull-out.

Steel Construction Applications

Use these application types when fastening metal sheets, flashings, and roof/wall components to steel members. Common steel construction use-cases:

Sheet-to-sheet stitching (overlapping joints)
Sheet metal applications
Z-channel purlin
For steel (general steel substrate fixing)
Crest fix to Z-channel purlin
Wall cladding to Z-channel purlin
Pierced fix
I-beam
Thick steel
Valley fixing on wall/roof
C-purlin
Z-purlin

Best for: Pre-engineered buildings, industrial roofing/cladding, structural steel framing interfaces, flashings and trims, and steel roof purlin assemblies.

Timber Construction

When roof/wall sheets or components are fixed into timber substrates. Timber application

For timber

Best for: Timber purlins, timber roof structures, sheds/warehouses with timber framing, and retrofit jobs involving timber members.

Concealed Fixing Construction

For projects that require a hidden/secret fix method for cleaner roof lines and aesthetics.
Concealed fixing application types

Purlin concealed clip
Concealed fixing

Best for: Concealed/secret-fix roofing profiles, architectural roofs, and projects that prioritise a clean external finish.

Light Weight Steel Construction

For light gauge steel framing systems and panel frame assembly.
Lightweight steel application types

For steel
Thin gauge applications
Light weight steel frames

Best for: Light gauge steel trusses, framing and panel systems where pull-out resistance and proper thread engagement are critical.

Concrete Construction
(Light to Medium Masonry)

For anchoring and fastening into masonry or concrete where pre-drilling and correct embedment are required.
Concrete/masonry application

Light to medium masonry

Best for: Light to medium density masonry/concrete fixing points, general construction attachments, and situations requiring controlled embedment and edge distance practices.

Board Fixing Construction

For board installations into steel or timber, including thinner sheet metal or heavier board conditions.
Board fixing application types

Board to steel
Board to timber

Best for: Drywall/board installations, internal partitions, board-on-frame assemblies, and projects needing secure holding with reduced risk of overdrive.

Harsh Environment

Construction

When corrosion resistance and long-term durability are key considerations (coastal, industrial, high humidity, etc.).
Harsh environment application types

Crest fix
Wall cladding
Overlapping sheet

Best for: Outdoor and exposed roofing/cladding, aggressive environments, and long-life envelope applications.

Skylight & Fibre Sheet
Construction

For polycarbonate/fibreglass skylights and fibre cement roofing where sealing and correct fixing style are critical.
Skylight & fibre sheet application types

Water sealing
Polycarbonate or fibreglass skylights
Fibre cement roof

Best for: Translucent roof sheet installations (skylights) and fibre cement corrugated sheets requiring appropriate sealing and profile support.
