I haven't tried this but it covers 4mm https://www.tetools.com/No.8544-1-4-Drive-Impact-Stud-Extractor-Chuck Jack

Based on Facom but made in China - at least they are now. The "premium" version is, I believe, made by Irega and is made in Spain. Jack

Thank you, much appreciated. Jack

I think this is a topic that always requires an explanation of context, otherwise it is ambiguous and the conversation goes in circles. Spline is often a general description. What is often called spline, is actually triple square - also called ZXN. It has 12 points with each point being 90...

Thanks again and yes, I understand that. Meursault74 said: The water has no metallic ions in it and has a better ability to leach them out from the metal surroundings over time. The implication here was that those contaminants were not required. Anyway, all good. Jack

Thanks. I'm not a chemist so I won't go on but I am surprised that DI water and distilled water can corrode metal unless it contains dissolved oxygen, CO2 or other contaminants. Hydration of aluminium oxide is one process, but that is very slow. I guess I'll just have to remain surprised. Jack

Is that because it was not properly demineralised in the first place, or because it was contaminated afterward by, for example, absorbing CO2 and becoming acidic? Of course distilled water also readily absorbs CO2 so both can have a pH as low as 5.5. Thanks Jack

What is the purpose of the blend? Jack

Distilled water is pure water - it contains no contaminants, no ions. Deionised water is a cheaper alternative that can be used to top up batteries. It can contain contaminants but no ions. Either is probably better than tap water in a radiator but coolant is best. Jack

If there is no flow meter, it is the wrong tool for the job. Jack

If you are concerned that the indicated flow will be incorrect if you add an elbow, then fear not. The indicated flow is the same at the nozzle as it is at the outlet of the flow meter. Jack

The coffee maker is in the kitchen, but shares the living room circuit. There have been quite a few comments about this peculiar arrangement. Jack

Apologies for the image, but just extent the lobe - or make a double lobe - as shown top left and the "slop" is gone. The geometry of the lobe and the contact point on the fastener remains the same for both forward and backward movement but the travel is reduced. I appreciate what you are...

You've missed my point entirely and I think we've all moved past the fact that a 13mm socket can't be exactly 13mm. How does every other manufacturer achieve off corner drive without a large amount of backlash? The backlash is not needed for off corner drive, but it is useful for the purpose...

No, not really. The profile of the driving surface is what is important. How is it necessary to place the reverse surface several degrees back further than is necessary to place the socket? Move those opposing surfaces closer together to remove the slop but retain their profile. Of course...
