Permanent screw connection, neat appearance
The lower thread cleanly secures the slat to the support structure. The narrow cylindrical head creates a clean appearance on the terrace surface. Pre-drilling further enhances this effect.
Precise positioning without splitting
Precise screw positioning is not an issue due to its centring drill tip, which was specially designed for this purpose. Drilling cutting edges ensure optimal drilling performance, similar to a wood twist drill bit, and wood does not split even when drilling close to edges.
Simple and clean countersinking
The cylindrical head can be simply and cleanly countersunk due its small diameter. Countersinking is recommended for aesthetic reasons.
AW recess for optimal positioning and power transmission
The AW recess ensures a secure fit of the drill bit in the screw. This prevents wobbling and prevents the drill bit from slipping out of the screw while screwing.
For screw mounting of hardwood planks
Preliminary testing is required for hardwood. Pre-drilling of the wood may be necessary depending on the thickness and level of humidity. We recommend running the application tool at low speed.
The range of applications for the various stainless steels can be found in the following ISER table (Informationsstelle Edelstahl Rostfrei - German Stainless Steel Development Association, information sheet 828).
In terms of weather conditions, only stainless steels (e.g. material no. 1.4016) are recommended for use in rural environments, and always with significant restrictions.
We therefore recommend using only austenitic stainless steels for outdoor applications, taking into account environmental conditions.
