Hi

Sorry next question :D busy day on boat yesterday

Screw.jpg

When removing Chartplotter, I realised that a screw on the Binnacle was not properly threaded into nut.
So manually undid it.

When to tightening it up and realised it looks like an Allen key but with a pin in the middle.

Where can I get something to tighten it up or am I better replacing it with a "normal" bolt.

Thanks for any help

Also called a "security Allen" / "security hex" screw....you can buy specific bits for these that go in one of the universal drivers...or more normal Allen keys with a hole drilled centrally.

If in a pinch, and have a drill press ideally, you can simply drill a small hole in the centre of a standard Allen key.
 
Managed to get any I have come across out with a screwdriver blade of the right size wedged down one side between the pin and 2 sides of the hex. In fact you can break the pin out that way on the smaller ones so an ordinary allen key then works. Mum's microwave had them and I needed to replace the turntable motor and did not have the right tools handy. I guess it may stop someone with no DIY/Bodging skills.
 
I bought a set that had the ones with the holes to tackle the pin screws, along with the ones I wanted. Now, where can one find the ends to match the triangular anti fiddle screws?

For a similar price you should be able to find a set of small hex bits which includes the triangle. These bits are smaller than the usual 1/4" hex, often in a 31-piece set with handle, IIRC. Search ebay for "31-piece precision screwdriver set" or something like that.

Your question has been answered, but if you're stuck and don't mind a bit of bodging you could file a couple of small flats on the edges of the bolt head. Then use pliers, spanner, adjustable or whatever.
