Description:
- TDBL = Standard version with thread-free zone
- TDBLF-T = Reduced thread-free zone under the head
- TDBLF-T-F = Reduced thread-free zone under the head, additional very flat head
Advantage:
"
simple- only one type of fastener for a wide range of applications
- easy positioning in the pre-punched component thanks to viewfinder tip
- same drilling diameter for all steel qualities
fast- fast and convenient processing with cordless impact screwdriver or tangential screwdriver with magnetic bit
- can be assembled with one hand, from one side, with just one tool in all positions
- thread-forming in various steel hardnesses and thicknesses
safe- no overturning in thin steel thanks to thread-free underhead zone and additional underhead serration
- no independent unscrewing thanks to patented thread
- increased work safety thanks to processing with just one hand
"
Technical Data:
Assembly tool: impact wrench or tangential wrench with a torque of > 150Nm to 650Nm (depending on the respective application)
Application Notes:
"Previously, pre-punched components had to be connected using standard screws, washers and nuts, which was time-consuming and laborious, and the connection had to be accessible from two sides.
The new nonut® TDBL thread forming fastener now enables simple, fast and secure direct screwing of statically stressed metal components. The TDBL thread mould fastener is inserted into the punched hole and screwed in in a single operation using a cordless impact wrench without tiring."
