ok so i looked through hondaautomotvieparts.com and sl honda cant find this bolt. if any one knows id rly appreciate it. cant drive without it...its the one the guy in pic (borrowed from another H-T member) has the hex key in. Thanks

 

just go to home depot and get a brass plug fitting there in the plumbing department.

 

I would go to mcmaster-carr (http://www.mcmaster.com/) before home depot since home depot is nto likely to carry brass or copper plugs in metric thread.

 

It's a 1/8 BSPT plug. McMaster Carr now carries them.

 

home depot has em I got a few to weeks ago and yea its not a metric thread

 

my home depot dosent. i work there everything my home depot carries is in npt thread not bspt
