What size Allen wrench is correct?

I tried both my SAE and Metric with no joy.

Thanks.

2.5mm

Fortunately when I ordered the rail stabilizers from Earley off of gunbroker one was included.

My 2.5 was too small, the 3.0 was too big. ?

My rifle is brand new.

1/8" would be a little smaller than 3mm. ???

Let's see:
1/8 = .125
3mm = .1181.
2.5mm = .0984.
My guess based on this and not having a Gen2 is that it is 7/64 = .1094

Like I said, I tried both American and Metric. No joy here.

I'm thinking that KT has sourced some oddball size to save a penny. I'm not going to like that much if it's true.

It's 2.5 mm. Metric.
I'm sitting here looking at my 2nd gen and that's what it is.

 

[Catshooter]

I don't doubt your's are. But mine aren't. The 2.5 (I have several) is too sloppy a fit. The 3.0 are too big. Same with the American sizes, ones too big and the next size down is too small.

And just to let y'all know, I'm not a twelve year old in my mom's basement. I'm a retired electrician with about 50 years experience gunsmithing. My Allen wrenches are all of a high quality.

So it looks like KT has used an oddball sized screw. Mmmm.

Earley claimed his product came with a 2.5mm allen wrench. The one I got in his package is stamped 2.5 mm USA on it so its a high quality one. Fit my Sub2k gen 2 screws perfectly. Since your saying multiple 2.5mm allen wrenchs were a sloppy fit then it probably is the screws. Maybe contact KT customer service and see what they say about it. Perhaps a running change in production and they have in fact changed the spec. Or utilized a different supplier that didn't supply the correct part this time around? Drawing at straws here honestly but those are the potential scenarios I think of putting myself in your situation.

Best of luck and hope you get it sorted out.

 

[Catshooter]

Good thoughts willis. I think I will contact them.

One of mine is a 2nd Gen, and I have serviced several others. All were 2.5 mm.

 

[Catshooter]

I believe you. I wish mine were too.

[WPhilB47]

I believe you. I wish mine were too.

Call KelTec and ask if there have been any changes.

 

[Catshooter]

I've emailed them. The tech mailed back that they're 2.5mm. I said no mine aren't. No reply as yet.


Cat

 

[haugrdr]

Ya might want to pick up a new 2.5mm Allen wrench.

 

[850sub]

I have more than one set. And a bunch of extras. I try not to mix them up.

 

[Catshooter]

I also have several sets. None fit.


Cat

 

[WPhilB47]

I think we've pretty much covered this subject. Live with it, send it back, or take it to a gunsmith.

 

[moetallday34]

Mine is the same way...most of the screws are 2.5 and 2 of them are just no size at all. I tried calling kel-Tec but after 45 minutes on hold I just hung up. I will try them again this week.

 

[Catshooter]

Yes. The nice lady at Kel Tec told me she had no answer. Everyone she asked said they should be 2.5mm. I'll have to make a wrench. She said she'd send me a full set of screws that are 2.5.

*sigh*
