Specification notes for ordering
Confirm the exact roofing nailer model, coating requirement and carton quantity. The large-head format is not a universal fit for ordinary pallet coil nailers.

APPLICATION EXAMPLES
Where it's used
Explore the materials, joints and workshop tasks below. Match the fastener size and tool to your own workpiece before ordering.
Asphalt-shingle fastening
Match large-head coil nails to the shingle specification and dedicated roofing nailer.
Ridge-cap build-up checks
Thicker ridge components may require a different nail length to achieve the specified penetration.
Shingle-and-deck sample review
Review head seating and required deck penetration on the complete roof build-up.

Covering → fastener → substrate → exposure
Large-head roofing coils and pallet coils have different selection requirements. Match the head geometry, shank, length, finish and coil format to the roofing nailer and roof-system instructions.
- Identify the exact roof covering and substrate.
- Follow the roof-system manufacturer’s installation requirements.
- Specify the head or washer, required penetration and corrosion environment.
- Confirm local project requirements and product documentation.

Assembly dimensions and tolerances are the published drawing reference. Confirm them against the supplied nailer and the agreed production drawing.
Choose for your workpiece and equipment
01
Check head, shank and coating together
Specify head and shank dimensions from an approved drawing, then confirm the finish and coating requirements against the roof-system instructions. Historical dimensions are not used as current ordering specifications.
02
Match the roofing nailer
Verify permitted head diameter, length, collation and coil format. A similar coil angle does not make a pallet nailer suitable for large heads.
03
Approve on the roof materials
Assess feeding and flush seating on representative shingle and deck samples. Verify required fastener documentation before approving the product for a named system.
Questions before you order
Are roofing nails and pallet coil nails interchangeable?
Their head geometry and applications differ. The roof specification and the nailer’s approved fasteners must both be satisfied.
Does a galvanized description confirm roof suitability?
No. Confirm the coating type and the roof-system or project requirement, especially for corrosive environments.
Application limits to check
- Do not substitute these for pallet coils or assume CN-series compatibility.
- Do not use an ordinary large head as a substitute for a specified underlayment cap fastener.
