What type of screw is this?

TheJackah

There’s these shelves we are trying to remove but no standard set of screwdriver bits we have fits on them or turns them. Does anyone know what type of screwdriver bit is needed for this?



Flat head doesn’t work.

Looks like s chewed up pozzi.

Definitely pozi (PZ), but they have up to 5 sizes (1 - 5). Most common are 1 - 3, but 1 is for very tiny screws.

The rule with pozi is that the size that fits is the next size up from the one you think will fit

That's definitely a knackered pozi head screw.

Looks like somebody has tried to use Phillips head to remove Pozidrive screw and knackered the head.

There are quite a few methods of removing screws such as extractors, cutting a slot with a Dremel etc.
You might be able to get a small pair of mole grips on to get it loose.

Does not look too bad. And elastic band and the right pozi head should do it.

Bash it off with a hammer time.
