IF you require a higher level of tamper-resistant screw coupled with the knowledge and peace of mind that the removal tool is not readily available, then the Cinstar screw, from Endeavour Tools , is what you need.
Cinstar is a new dimension in security fasteners. It offers high torque installation in A2 stainless steel with access to driver bits limited to authorised users whose names are kept in a register.
This new range provides extra security not available with other types of security recesses.
Endeavour has added the Cinstar to its powerful line up of security fasteners, the new five star recess with pin offers five times the security of ordinary machine screws.
The Cinstar screw is available in M4, M5, M6, and M8.
