Conrod Bolts
Conrod Bolts
(OP)
I'm refering to the type of connecting rod bolts that have a reduced section in the shank (i.e. less than the thread minor diamer). Is there a special name for these type of bolts?

RE: Conrod Bolts
The reduced section fastener is also use to make a bolted joint that is more flexible as with temperature extremes. I've heard this type installation called a flexible connection.
The aero people may have a name for this type fastener.

Other than OEM or replacement parts called out by a part number all the orders I've seen for this type fastener are called out by print.
Every great once a while a order will say by example, the requestor is asked for a print or it is a no quote.

shank break before the threads strip
which would be really bad news.
RE: Conrod Bolts
Swall - when you say the shank stress area is smaller than the thread stress area, how are you calculating thread stress area, there are several methods for this depending upon the predominant failure mode. 'Stress areas' are not always the same when condsidering hi-temp and low-temp load situations, partly because the residual benefit of cold work in a rolled thread (and all con-rod bolts will have rolled threads) is different in the two cases. What in fact is done for con-rod bolts is actual tensile tests on the bolt, that way the user is sure of designing either the shank or the thread slightly stronger, as he wishes.
