Im trying to find the correct name for a type of machine screw (for eBay/online shopping searches).

It has a head like a carriage bolt (large pan, say 20mm in diameter, but only 5mm thick in the middle and tapering to a thin circumference), but without the square top to the shank. A combi slot in the top (slot/posi), M8 thread from the top of the shank and about 20mm long.

anyone?

I sometimes see button head screws with wider bases - they look like they've got washers under them but it's integral. Not in M8, though. Button head with a washer?

I may end up having to use a pan head machine screw and washer, but was hoping to keep a lower profile.

Stigs fasteners have been good when I've wanted stuff

The thing your after looks a lot like a B&Q roofing bolt but they are for a flat head screw driver.

It sounds like a roofing bolt, the sort of thing to hold corrugated sheet to metal rafters / trusses

Yep B&Q had M8 roofing bolts, but they were slotted not Allen / Phillips / Pozidrive

I use these flat head furniture bolts quite a lot. Neat and flat. Usually m6 but you can get other sizes.
