No thread and burr on slot
No thread and a shallow off-centred slot
Another abomination of a screw. There’s just no knowing how long this screw used to be or what it was destined to fix together!
Must have got caught in the machinery somewhere. It’s been bent at the top and has a couple of small gouges where it’s been pressed at the end
Strange one this one. It looks like it’s been cast rather than milled due to its all-over mottled appearance and rough deep slot
Another small one with a double defect; the end doesn’t taper off to a point and the slot is ff-centre
