Inspection cover scews

[Lincolnshire Ian]

Hiya

I have quiet a few Wavin inspection chamber cover screws which are damaged.

Does anyone know where I can get some replacements. 

Groundworkers long gone. 

Thanks

The screws are pants, in the past I have drilled the holes and tapped M8 then used M8 stainless countersunk set screws with head for hex key. You could probably get away with M6 but I just had some M8 available.

Its worth doing a @markc above anyway because stainless set screws reduce the annoyance of lifting the  I/C cover when - several years later -

you're in a hurry to get it lifted .

 

And, of course, the slot for the screw driver has been buggered. Might be worth a Torx screw head (?)
