TORX PLUS® IPR bits
The TORX PLUS® IPR profile is a 5-flank TORX PLUS® profile with bore hole. This drive geometry was reduced by one flank and provided with a bore hole to protect safety screws against undesired loosening. These screws cannot be turned with conventional, widely available tools. Sales are only to authorised customers and authorisation has to be evidenced in writing.
TORX PLUS® IPR bits by Wera are just the right tool, also for your requirements!
