Over-torqued rail screws.
Solutions for Stuck Screws:
There are two ways that you can loosen stuck rail screws using tools that you may have on hand:
- The first way requires a T30 Torx socket and a socket wrench. Using this combination provides much greater torque onto the screw head and should loosen it easily.
- The second way requires a T30 Torx bit and an electric drill. In this method you tighten the bit into the drill and use the drill as a wrench. Do not turn the drill on. Loosen the bolt by hand turning the drill as you would a wrench.
If you don’t have these tools on hand please contact *Schneider Electric Tech Support to RMA p/n 0M-5383. This is a T-handle combination Torx tool. It provides more torque than the included L-shaped tool, but not as much as the methods outlined above. The 0M-5383 can be used as a Torx screwdriver or T-handle wrench. To loosen stuck screws you should use the tool as a T-handle wrench.
