Stainless Pan Head Bolts
A2 and A4 Stainless Pan Head Bolts/Screws are shown below in various drive types. Almost exclusively
fully threaded and a very popular head style, shaped like a saucepan, with rounded sides and flat underside.
There are some differences to the top profile, generally to accomodate a different drive type, a slotted
stainless pan head bolt will have a flatter head top.
