If you don't have a specialized, long-neck security screwdriver set on hand, you have to get creative. Here is how to conquer the proprietary screw trap using a bit of smart workbench improvisation.
The Tool Dilemma: Teeth But No Jaw
The main obstacle when dealing with modern extension blocks isn't just the shape of the screw, it’s the depth of the recess. Standard bit-driver handles are usually too thick to slide down into the narrow plastic channels.
For this specific teardown, I evaluated two potential candidates:
●The Backup (Triangle 2.3): Upon closer inspection, this bit is Philips screw driver bit.
●The Hero (Triangle 2.0): This bit is the perfect, crisp match for the internal geometry of the extension block's fasteners. The sizing is exact, meaning zero risk of stripping the screw head.
The catch? I have the loose Triangle 2.0 bit, but no driver body thin enough to hold it and reach down into the hole.
Because the Triangle 2.0 bit is entirely sufficient to turn the screw, the project now shifts from a tool-hunting mission to a pure mechanical assembly problem. All that is left to do is locate or improvise a slim, rigid driver body that can:
1. Securely grip the base of the 2.0 mm bit without slipping.
2. Maintain a narrow enough outer diameter to clear the walls of the extension's deep screw holes.
3. Allow enough manual leverage (torque) to break the factory thread-lock.
Whether it's an ultra-slim precision magnetic extension bar, a micro-socket adapter, or a carefully locked pair of needle-nose locking pliers on the bit's shank, a solution is close at hand. Once the bit finds its body, this 65 W casing is as good as open.
