Thread: Are you using a #2 or do you have something better

I've been using a #2 Phillips screwdriver bit to disassemble and reassemble a CT-70 motor that I've been working on. I'm not completely satisfied with how the #2 Phillips bit fits into the screw heads.
It's almost like the bit should be bigger. There's areas on the outer edges of screw that do not come in contact with the #2 bit.
I've seen this as well with a brand new Craftsman #2 phillips screwdriver.
A #3 bit or screwdriver is to big, is there something in between a 2 and a 3 that I'm not aware of?
What are you folks using?
I hate seeing the screwheads all "boogered up" because the driver doesn't get a solid grip on them.

I use a craftsman screw extractor...the kind you line up and smack with a hammer....works everytime and doesn't bugger them up. However, the only way I put the originals back in is if the motor is going in for a restoration...otherwise I use either 8mm cap screws or allen bolts.

I typically use an impact driver and I have a case of different size bits for it and a screwdriver also...I have no idea what size they are...I have noticed that different screws that look like the same size are not...I don't know why....The motors have never been accessed.

If you can't get them out with a screwdriver, you can use an impact, drill them or use grab it...They work well.

I usually replace the screws with new Honda screws . They are not that expensive & look great . Use blue loc-tite with reassembly .

Better skip the Loc-tite! Use Anti-seize instead. If you though they were hard to remove the first wait a couple of years with Loc-T. Not needed. Factory didn't use it so you don't need to.

there chinese so they are made to operate backwards..sorry could not resist..i use the bits and have found they work better then any screwdriver

#"O" actually. JIS - Japanese Industry Standard. Works great however I do use the impact on many engine screws since they are godawful tight.

I don't even try to remove a phillips head screw on a 20+ year old bike without a 19.2V craftsman impact

When factory put them in there was no loc-tite . Use loc-tite medium strength (blue) .
I've used this for many years , with no problems .

Thanks ! I had know idea that there was a Japanese Industry Standard. Do you know if you can get that size/style bit that will fit in an Impact Driver?
