In one of his Tally Ho videos Leo explains the benefits of slotted screws any why he uses them on the build. Don't presently remember right now though. As far as phillips screws go lets not forget about pozi drives

There is also posidrive, similar but not the same to Phillips and JIS but has an extra 4 slightly smaller flanges at 45° to the primary onesLet us add another twist. There is a head similar to Phillips used on Japanese motorcycle, the JIS (Japanese Industrial Standard). Whether it is better or worse than Phillips is irrelevant. A Phillips driver works, almost, and most old Japanese motorcycles have JIS fasteners that have been wienered up by a Phillips driver.

Please check for one of my several 10mm sockets. They're like socks.

On any rebuild some of the screws will require their heads to be drilled. Slotted are the worst for this. Plan ahead.
Does anyone else think that while Robertson’s may well be functional they entirely lack aesthetic quality? Like a farmer’s pathetic attempt to improve on the Allen head.

The other thing, it's very easy to dress a flat tip. Phillips possible but more difficult. Other screw types, forget it. The answer is to go buy a new one.
Yeah, old fashioned as shit. But when I hear people bitch about slotted head screws, I think that their mechanical trades education has not covered some fundamentals.

I’ve found this nice screwdriver set, only has one Robertson and Allen key size, but useful handle to allow T bar as well as standard screwdriver handle grip. I’m sure there’s lots of great stuff available in hardware stores in the US.

The thing about JIS is that in the 60s and 70s and later, the blossoming Japanese motoorcycles were all fitted with JIS and EVERY backyard mechanic/service guy used Phillips and wienered the fasteners. I have since replaced most with allen head screws on my 70's motorcycle projects.

It would take all day to count the visible slotted screws on my boat, and every effing one is clocked. They do look way nicer than Robertson. Anything I build I use Robies, but you can't see them, no visible fasteners. Robies go frm #4 to 00, generally.

The daggerboard case on my new boat was air tight and swole at a high altitude lake, pinching the board. This is the one time a Phillips head screw saved the day. I found a brass Phillips head screw to replace a stainless Robertson fastener on the case, took my smallest drill bit and drilled a vent lengthwise through the brass screw. Viola!
We agree that Robertson screws look rather industrial. FWIW the electrician that did my house clocked the screws on the outlet and light switch plates.

Yeah, you need to grind the tips down on a few appropriate-size Phillips bits for those. Works a charm.Let us add another twist. There is a head similar to Phillips used on Japanese motorcycle, the JIS (Japanese Industrial Standard). Whether it is better or worse than Phillips is irrelevant. A Phillips driver works, almost, and most old Japanese motorcycles have JIS fasteners that have been wienered up by a Phillips driver.

Clocking screws is one of my OCD traits, I don’t recall where I picked it up about 30 years ago but ever since then I have to clock EVERY freaking screw I tighten or I start chanting about pancakes on Tuesday. The thing about it is that in places where many screws are used most folks don’t notice or realize it’s been done but it adds a finer “finished” look to the work. Yes, all the way down to wall plates.
