[sethman919]

I went ahead and bought 100 of these to help save folks a few bucks.

$2 each plus $3 shipping. if you want more than 2 or 3 the shipping may go up a little.

Hi,
Any chance you can send to Australia? They only have up to #3 over here. I ordered some online (made in China) and they just striped - not stainless steel
Thanks,
Chris

Sorry….stripped!

 

[sethman919]

Sorry. This post is really old. I don’t have these anymore.

 

[ChrissoSX230HO]

No worries thanks for getting back to me ?

Out of curiosity, what are these needed for (or used to be needed for back in the day of '18)?

 

[sethman919]

They were needed for 230 series boats and maybe others.

 

[ChrissoSX230HO]

Yeah the #4 Robertson bit is for the stainless steel screws that secure the fuel tank cover in the cockpit floor of my 2007 SX230. Can’t get a #4 over here and Lawsons doesn’t ship to Australia. More research required.

If you guys haven't watched "Mitchell's versus the Machines" on Netflix.......you seriously need to. The #4 Robertson head no slip screwdriver is a KEY part of the story.

Grab the kids and have a good laugh. Guarantee you'll never think about a #4 Robertson head no slip but the same ever again!

Thanks mate I’ll try and track it down

Thanks BigT, this was the kit I got from Amazon. I tried to use them and they seemed to strip the bit heads. Reading some of the other posts about undoing the fuel tank screws, I have to admit that I didn't tap them down with a hammer before trying to undo them. I also didn't use the method of loosening a little then tightening a little and so on. I'll have to give it another go, thanks for responding to my post, cheers

Good to know, I just got a set but haven't tried to use them on the screws yet. Did you us them with a drill or by hand when they stripped? The tapping down recommendation seems like it might help to prevent the stripping.

 

[ChrissoSX230HO]

I was using a Milwaukee cordless drill when they stripped. Looking at my screw heads some of the Robertson "squares" were already a little worn, the previous owner may have attempted to get them out. I'll have another go next week, my wife has put me in quarantine as I've just caught the dreaded Covid for the 1st time. Good luck getting yours out.

I recommend an impact rather than a drill. The impact will push down as it turns.

The set on Amazon is a great find!

I have thought that this type of tool might be better suited to the job. https://www.amazon.com/ARES-18021-1-2-Inch-Manual-Reversible/dp/B07W95GVSD

This was my experience removing them https://jetboaters.net/threads/my-e...nk-access-hatch-to-add-sound-insulation.6309/

I've just ordered the ARES tool as per your link, looks like it should do the trick. What a pain your experience was, plenty of patience required but well worth it in the end by the look of your photos. Thanks again fro the info and thread

Please let everyone know how that impact works. I am hoping it will break the screws loose without stripping or breaking.

Will do Bruce, expected delivery June 2nd!
