What’s It Actually Called

[sherrardk]

Need to buy a big bolt - it’s 110mm long, Allen key screw bit, smooth for the first 65/70mm (bit by the head) and grooved like a screw for the rest of the length. The bottom is flat (not pointy like an actual screw) and it’s brass/brass coloured. Anyone know the technical name for it so I can actually find one to buy?

Socket cap head allen bolt.

[sherrardk]

Thanks both, that looks about right - do they just come in a standard thickness?

[tonyav]

No, sherr. Different diameters.

If you don't mind me asking, what do you want to use it for ?

[sherrardk]

The roof part of my swing seat got battered last night and one of the screws holding it on has gone AWOL and the other is bent and stuck in the frame (borrowing bolt cutters to get it out). Probably won’t bother putting it back on till next spring but if I don’t buy the bits now I’ll have no chance of remembering what I need.

The head of the bolt should have an A number stamped on it. A2, A3, etc. That gives the key size I believe, it may also have an M number this with be diameter and thread detail ie M10(10mm), M8(8mm). This may help.

Ah I see, you'll probably find that the bolt is dichromated zinc plated ( looks a bit like brass .

These are probably the most used size for furniture use.
