bolt question

May 27, 2005 5 Replies

I am looking for a 3/8"-16 bolt about 1/2" long with a smaller than normal (9/16") head. I think they are called flange head or something like that. Also it has to be stainless. I check mcmaster but can't find one. Thanks


Might try

You might have to mill the head to size.

I think that you are describing automotive header bolts. They are used to affix tubular headers to engines and have a 7/16" head and a flange. I'm not sure about stainless but they have chrome.

Habbi, I use these folks all the time. They will have your item in 12 point and 6 point.

I will look at them. I am going to make a gearcase drain plug that is not prone to stripping. The one in my 250 Johnson has a 5/32" allen head.
