Williams WRS-1 ratcheting screwdriver

[Wamsutta]

The Williams WRS-1 takes the same mechanicals as a Snap-on SSDMR4B ratcheting screwdriver, correct?

So I can use the same rebuild kit - which would be RKSDR1, correct?

I don't know but I would like to know if the toothed center gear has dimples internally for the shaft retention.

My Williams t-handle accepts ball retention shafts. It was the OEM Williams mechanism it it.

Have you had it apart to verify ball retention divots?

You verified it does not.
Accepting ball retention shafts is different than retaining them well.

Youre are correct with your reference to my previous thread. Being as I cannot confirm or deny they are there, some have said hard to see if they are or not, what I can tell you is there is very positive retention with the shafts. The gearwrench shafts I purchased after that thread hold fast. Granted they would not hold ten pounds but you wont loose a shaft in a hole with say a 1/4 drive adapter and 9/16 socket and bolt.

OP the snap on gear fits in ny Williams t-handle. Though I gave my Williams screwdriver to my BIL so I cannot confirm 100% on that front, Odds are in your favor.

I would just add a magnet to mine but the original bit driver shaft is non-magnetic and I believe stainless. It lacks ball retention.

The 1/4 sq. drive shaft I bought from SO is magnetic and probably chrome. It is from the soft handle collection and thus has ball retention.

It seems if the repair kit mentioned above has divots in the female square, it and a bit driver shank are the full answer.

Snap-on ratcheting screwdriver shanks are stainless steel.

Snap-on ratcheting screwdriver shanks are stainless steel.

if so, unfortunate they went to a magnetic grade in the SGDMRC4-TM4.

Do you have any SO HH drivers? Or the kit mentioned by OP? I would like to know if they have divots for ball retention.

Apparently there is a belief that all stainless steel is non-magnetic. A basic stainless steel has a 'ferritic' structure and is magnetic. For more information see: http://www.physlink.com/Education/AskExperts/ae546.cfm and http://www.bssa.org.uk/faq.php?id=24.

The following link is to a Snap-on document where it is mentioned that Snap-on ratcheting screwdriver shanks are stainless steel:

What I intended to convey in my earlier post may have more clearly been phrased as "if so, unfortunately they went to a magnetic grade of stainless steel in the SGDMRC4-TM4. "

I will be honest, I don't know how unfortunate it truly is, had they indeed changed from non-magnetic (as the original bit driver shank happens to be,) to a magnetic grade of stainless.

What I do know is the sq. drive shank I ordered and received from SnapOn in 2014 very much appeared to be chrome.

And as of this morning, Snap-On had this to say regarding the materal. (They also clarified a service kot PN for me.):

" The SGDMRC4-TM4 is made of a standard steel, not stainless."

I think we can assume the linked PDF in your post has the potential to be outdated or at least was "accurate enough for the marketing Dept."
