RAPID® Dual
The hexagonal recess allows for better force transfer
- recommended for woods with higher density and impact drivers
- Additional T-drive saves the time of changing tools
- Optimum fit in steel bores thanks to underhead shoulder
Ø 8.0 x 50 to 400 mm
Ø 10.0 x 60 to 400 mm

Features
Minimised effort
- With hardwood screw development innovations
- Significantly reduced turning resistance from the friction part
- Longer battery life for screwdriver
Fastest screwing processes
- Dual thread with high and low flanks
- Accelerated screwing proceesses save time - compared to conventional wood construction screws.
- The highest technical values guarantee a secure hold, even for oblique and cross grained wood screw connections
Low splitting, little resistance
- The wavy profile on the flanks reduces splitting and screw-in resistance thanks to the cutting function
Patented tip - no pre-drilling necessary!
- Self-drilling tip with ridged core
- Saves time by biting precisely and instantly, even with oblique and cross grained wood screw connections
- Much less splitting and lower screw-in resistance compared to conventional wood construction screws

Applications: RAPID® partial thread
Partially threaded screws enable the stable connection of two components. The thread must be completely in the lower component. During screwing in, the thread pulls the attachment part = upper component, onto the lower component and fixes it. The characteristic values of head pull-through and thread pull-out are relevant here.
Doubling Rafters: Doubling for reinforcement is usually done on the top or side of the rafter.
Rafters: Partial thread screws transfer the wind suction load and shear forces to the substructure through the screw heads.
Metal sheets and shaped sheet metal parts: RAPID® Dual and RAPID® SuperSenkFix screws are optimal for metal sheets and shaped sheet metal parts. These screws have an underhead shoulder which allows them to be optimally centred and to fit perfectly in the metal.
CLT walls and ceilings: Cross-Laminated-Timber (CLT) - ceiling panel screwed to the walls with RAPID® SuperSenkFix. Schmid screws are approved for all applications in side and end wood (0° and 90°) as well as CLT side faces and narrow edges.
Corner and wall screw connections are pulled tightly together and securely screwed with RAPID® SuperSenkFix.
