2-56 X 1 1/4" Unattainable? Empty 2-56 X 1 1/4" Unattainable?

Post  rsv1cox Fri May 20, 2022 9:07 am

Checked everywhere, even our old friend McMaster-carr, nothing over one inch. Anyone got a better idea?

I actually need a 2-56 X 1 1/4" self tapper but I can make a standard thread work.

Seems like we have discussed this before.

Says, "Price per Bag: $14.79" of 100 pieces, a little pricey unless one has a bolt cutter for 2-56 then can have custom bolt lengths. Probably best universal is Allen head screws. Then can use also on legacy McCoy, K&B Torpedo and Stallion, Fox engines, too.

Don't know of anyone with smaller quantities, plus, shops these days carry mostly metric, hardly anyone uses ANSI. I've salvaged screws off old light fixtures, electronics, etc., which sometimes has saved me.

Times have changed.

Bob,
Could you use 2-56 all-thread cut to length and a nut?

Try the Bolt Depot?
I have been getting my bolt from there over getting them from McMaster - Carr

https://www.boltdepot.com/Default.aspx

2-56 machine screws:
https://www.boltdepot.com/Machine_screws_Phillips_pan_head_Stainless_steel_18-8_2-56.aspx


Sometimes they have unusual sizes and length of fasteners that I can't find somewhere else?

Thanks Eric, with 100 I have a chance to experiment.  I have a lot of one inch 2-56's but nothing larger.  I have had good luck putting a drop of Titebond on the tip and screwing them in, Just enough to secure and back out if needed.  Sort of like blue loctite on metal.

Bob is looking for 2-56 thread by 1.25 inches long, not 0.25 inches long.

No problem, easy to mistake, especially since different countries notate measurements in different ways. Smile

Except in a few cases, I almost always order 100 pks. of longer screws knowing that a little careful work with a Dremel cutoff wheel will give me any number of shorter screws. It saves money and aggravation in the long run.

I use this VACO crimping tool to cut 2-56s to length (roddie is a big fan of these). Just use the 4/40 slot. Gives a nice square cut that I dress up on the fine grinding wheel.

I also like the compartmentalized plastic boxes. I used to have everything in small plastic cabinets. This way I take the box with me. Harbor Freight roll-around too. Goes where I go. Just got these 12" long lengths of music wire assortment via ebay. I miss the local hobby shops of yesterday were I could buy individual pieces.

Bob, got a similar bolt cutter, wire stripper and crimp tool like yours, but a different U.S. make (back in the days when they still made tools), ChAmp. It was my father's, from the late 1960's.

2-56 X 1 1/4" Unattainable? Amp_ch10

The hard plastic handles gave out a few years ago, so I replaced them with

2-56 X 1 1/4" Unattainable? 61ybkv10
Amazon photo, Amazon: Klein Tools 60 Handles

Like the others mentioned, I did similarly on the 2-56 screws. Bought Allen socket heads in quantity for the longest used in the legacy U.S. made glow engines, 1980 and earlier that still use these threads (Testors McCoy, K&B, Fox, etc.). The ChAmp tool does a nice job of trimming them to size.

It is difficult these days to find these tools made of the stronger tempered steel that these were. The bargain ones sold just do not do the job. However, I don't do enough work to justify paying close to $100 for a "professional" version.

(And, I'd have to check, but last time I "overhauled" a bargain Bay engine, think these use 4-40 screws. Tool cutter doesn't have the 2-56 thread, so I use alternate methods to shorten in a manner leaving the cut end threads intact.)
