A4 Marine Grade Stainless SteelProvides exceptional corrosion resistance, making these screws suitable for coastal, humid, or chemically aggressive environments.
ETA ApprovedCertified under ETA-04/0013, ensuring compliance with European technical standards for load-bearing timber connectors.
Conical Head DesignThe underside of the screw head is shaped to ensure full surface contact with the connector hole, allowing for optimum load transfer between screw and fitting.
6-Lobe (Torx T-20) DriveProvides a secure fit with minimal cam-out during driving, improving speed and control during installation.
Type 17 PointPre-drills into timber as it drives, reducing the risk of splitting, especially in dense or brittle woods.
Optimised for Simpson Stainless Steel ConnectorsSpecifically developed to maintain the published load-bearing capacities of stainless steel hangers, brackets, and straps.
Stronger Fixed ConnectionsLarger cross-bearing capacity than standard screws, enabling secure structural performance in timber-to-connector fixings.
Ideal for Harsh ConditionsA4 grade stainless steel makes these screws suitable for exterior, marine, or chemically exposed environments.
Professional Finish and FitPrecision head design aligns perfectly with Simpson Strong-Tie connectors, enhancing both appearance and structural performance.
Fixing stainless steel joist hangers to timber
Attaching angle brackets and restraint straps in timber structures
Suitable for:
Solid wood
Glued laminated timber
Composite lumber
Ideal for exterior and marine environments or where high corrosion resistance is essential
Always use the specified CSA-S screw type with Simpson stainless steel connectors to achieve rated load performance.
Do not substitute with zinc-coated or lower-grade screws in corrosive environments.
Pre-drilling may be required in very dense hardwoods despite the Type 17 point.
