I was wondering where I could get hold of some nuts for a collins actuator, they are a m6x28 thread (not common) and whats more when I rang Collins they dont do the nuts anymore, only the studs and allen bolts are available.

 

are you sure they're not 1/4 UNF ?

 

I'm not sure, can anyone clarify this? I don't have an imperial pitch gauge, only a metric one and the m6x28 fitted perfect

 

1/4UNF are 28 tpi

 

spot on

ive just made a new actuator arm for a friend, and the thread is 1/4UNF 28tpi

 

thanks a lot for clearing this up, a total of 80p to get it sorted so I'm well happy
