Identifying the tool required to fit this socket (its to manually open a swedish cabio fabric roof)

Note: the protruding lugs on bottom of socket. If you use a piece of steel plate as a large screwdriver, you would crush those lugs.

What is the socket called. Are there ends you you can purchase for power tools or to fit 3.8 or 1/2 ratchet.

Welcome to the forum.

Why wouldn’t a large flat blade screwdriver work?

It looks like the bits in the bottom right corner would fit that cavity.

Amazon Security Bit Set

I think ‘wingless’ may be right. What is that bit or socket called (in case there are different sizes). The bit mentioned however doesn’t accommodate the lugs on the bottom. But may still work as you just can’t push it all the way in.

Thanks

The bits in amazon kit are imperial at 3/16″ and 5/32″, and I am unsure how these are measured, but if it is diameter, these are too small. Out socket is 8mm across.

It’s called a ‘clutch’ bit.

Thanks all.

OK, there are no clutch bits anywhere near 8mm diameter. This bit is called something else and is metric.

The proper tool probably accommodates the lugs that aid aligning and removing tool without chipping the nylon socket.

Any other ideas.
