Need a weird sized screw
Hi all I unfortunately broke a collared thumb screw off of my Stanley 386 jointer gauge , it is a 10/28 size which seems impossible to find, the threaded potion needs to be @ 1 inch long . I’m pulling my hair out as I have a project coming up which I need this tool. Stanley apparently used weird sized to keep people from using other parts, anyone have a lead for me? Much thanks for any help. Here is a picture of what I’m talking about. Drilling tapping is out of the question

Try sears hardware store, I know the one in Norristown has a lot of weird stuff like that. You'll have to look as they don't know what they have. 4-5 deep rows of that stuff ,also auto nuts and bolts.

This might work, maybe too short.
https://www.ebay.com/itm/THUMB-SCREW-10-28-THREADS-FITS-STANLEY-NO-78-FENCE-MORE/153145279131?hash=item23a82b829b:g:sMYAAOSwdmpZ4O5 q:rk:1f:1&frcectupt=true Ebay is going to be your friend for something like that. Old school machinist could make you the threaded section. Good welder might be able to TIG the broken one if it's not in the threaded section. Might try looking for a 10-28 threading die and make your own. |

Join Practical Machinist online forums and check with the guys on there. They are mostly antique tool collectors and machinists.

The 78 Stanley is a perfect fit but 1/2 inch too short. I tried the one I had here at the shop . Sears was a no go only 10/24 threads. I’ll try nhnllane parts thanks

How do you know it’s 10/28? Could it be metric, it could be an aerospace application. MS, AS, NAS, hardware may fit the bill if you are absolutely sure that is the true size.
Edit: I now know what you are working on: https://www.jimbodetools.com/product...er-gauge-72830

Not saying that what you have is not a 10-28 screw.
10-28 is not an American Standard Thread but 12-28 is. The diameter for a #12 screw will be .216 This is how to determine the Number of a screw when the diameter is known. #10 example .190 (Diameter of said screw) minus .060 (Standard) = .130 .130 divided by .013 (Standard) = #10 Screw The distance from thread crest to thread crest for a 28 TPI thread will be .0357 1 divided by 28 (number of threads) = .0357 (pitch) If you are unable to locate a replacement the next time we are running a #10 screw job we can sneak something in for you.

#10 screw is 0.190".
I assume 3/16" screw is 0.187" Some sewing machines use various 3/16-28 screws. Only guessing a 3/16-28 would fit for you. 25mm long is about 1" (Juko machine p/n SS6122510SP, they also have 30mm long (SS6123010SP). Not a thumb screw. Check these links for possible sources: https://www.abcsewingmachine.com/pag...ide-components See Item 14 on the illustration. http://www.pennsewparts.com/products...pagenumber=803 http://www.matparts.com/product_info...8ah8gghdt9gka0 |

Definitely a 10/28 screw from everything I’ve read online Stanley used odd sizes to keep people buying their parts

Might be a machinist near you that could make one. Or try to make one yourself not being smart.Get die, some stock,even larger thumb screw and cut down to your size. Change threaded portion of tool to another size, not good.

I looked around for 10-28 dies and could not find one .... plenty of 10-28 taps though.
Update: Just found one at MSC https://www.mscdirect.com/product/details/03928280 (I now see others available cheaper too) Some proper diameter drill rod or heat treatable tool steel .... turn down the threaded section and thread it, leaving a shoulder, slot the upper end, weld a washer on edge into the slot, heat tread with a propane torch and you are good to go. Chart showing UNS 10-28 thread dimensions. http://www.efunda.com/designstandard...ws/unified.cfm Ling to Singer Sewing Machine hardward, numerous 10-28 screws of various designs: http://www.singersewinginfo.co.uk/screw_threads/ Using this list: #10-24 UNC 0.1900 #10-28 UNS 0.1900 #10-32 UNF 0.1900 #10-36 UNS 0.1900 #10-40 UNS 0.1900 #10-48 UNS 0.1900 #10-56 UNS 0.1900 #12-24 UNC 0.2160 #12-28 UNF 0.2160 #12-32 UNEF 0.2160 #12-36 UNS 0.2160 #12-40 UNS 0.2160 #12-48 UNS 0.2160 #12-56 UNS 0.2160 I'd use buy a 12-28 UNF screw of the proper design and use a 10-28 die to cut it down, the die would have to shave off .0260", which considering it's the same thread pitch should be doable. Maybe file off some of the diameter of the 12-28 UNF first. That's all I got. Last edited by dataway; 10-26-2018 at 11:50 AM. |
