We’ve all been there: you’re staring down a piece of tech that desperately needs a minor fix, only to find the manufacturer has locked you out using proprietary anti-tamper security screws. Today’s opponent? A sleek 65 W power extension block protected by deep, narrow screw holes and triangle-head fasteners.
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.
The Mission: Hunting for a "Body"
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.
