are will it hurt to go 1 size bigger i need to finish getting the car back together and i need this damn screw are do i have to get them from littlefield


thanks jim

 

6-32 x 1/2" long is what my box says. But I have nuts on the back side (in the hallow of the rotor).

 

mine is also the same as SoDak..Dave

 

the ones in my rotors are a tiny bit smaller and a finer thread than a 6-32
if thats what you guys have then i can drill it out a little and use a 6-32 but mine are different

 

Jim: I know exactly to what you are referring. I have an older mag case Littlefield 14-71 HH and the 4-40 screws were too small, and 6-32's were too big. The screws ended up being 5-40's. I had never heard of that size but it does exist. I believe the rotors were retro-fitted with the strip screws (since the rotors have stake marks in them), and for whatever reason they used the 5-40 size. Littlefields said they only ever used 4-40 or 6-32, but maybe some other blower service place was retrofitting these rotors with screws using the 5-40 size??

Before finding the 5-40 size, I had thought about drilling them out to 6-32, but the countersunk head size is too small, and if you tried to enlarge that, it might protrude into the strip location too much.

I bought them at my local industrial supply store. If you can't find them, I could probably get them and mail 'em to you.

Anyway hope that helps

Chris

the answer is 5-40 i will try to find some locally tomorrow i really didnt want to drill them out because the counter sink has to be a little bigger also thanks for the help guys

woodchip the link you gave has them if i cant get locally i know where to find them

will thanks for the site its a big help to a lot of people


thanks again jim

 

if you are going to look locally try the hobby shops, that screw seems to be popular for hobbyists for some reason (via searches) i doubt you will find these at an automotive or hardware store. the box stores and pep boys chains put most of the mom and pop stores out of business.

Our blowers were brand new from LF with 6-32 in them. I specifically remember this because some holes had the threads stripped and had nuts on the inside, from brand new. I was not impressed I did like the blowers overall.

 

i found the bolts locally had to order the damn poly loc nuts i really didnt want to use a regular nut but i thought about it so i will have to wait till next week to start it its only time thanks guys for the help

 

jim how long till they can get them for you? if long i can send you some we have a big supplier her in town..Dave

 

supposed to have them by wednesday so had to order a 100 each if any body needs any i will have plenty my wore out blower will never need that many replaced ( lol )
