Help with Allen Head Cap bolts...

Hi,
Received today a new headphone amp. It is aluminium construction and uses 4 allen cap bolts at each end to hold the case together. It is all good (was cheap), but the bolts used are clearly low quality and don't look right. I would like to replace them but can't find details on what size they are (head looks about 3/16 (3mm) wide, and allen looks like 1.5-2mm). I would imagine the bolt is only about 10mm long max, maybe more like 5mm. I will have to unscrew to check, but I don't want to do this until I'm reasonably sure I can replace.

I'm sorry if this is the wrong forum. Anybody advise on the sizing convention for these type of bolts (metric and imperial-Im not sure which these are), and where to buy replacements?

Many thanks in advance

Welcome to PF, Lock.
The cap screw is just a head style on a regularly sized bolt. You can get a replacement with just about any head style you want. Just take one down to your local hardware store and they'll set you up with a match.
