I've got a cap head (allen key type) bolt with YPS 72.8 written on it. Can anyone tell me what the 72.8 relates to.
Cheers
Matt

Matt - are you sure it's not 12.8? I think most cap heads are 12.8 (or is it 12.9) tensile rated. If not I haven't got a scooby doo!

Yeh most are 12.9 - I'll have another look.
Cheers
Matt
