A note on Honda screws, or JDM screwdrivers
another title of this thread should be, "how tyson spent over $80 on new screwdrivers".
this is something that i should have mentioned sooner, but i dunno how many of you noticed how easily honda "phillips" head screws tend to strip easily. but another post came up recently and i thought i'd reiterate here.
The problem with these Honda screws is that you really need to use a "JDM SCREWDRIVER", aka JIS screwdriver. no joke. there is a difference!
the japanese spec screw is NOT the same as an ordinary phillips head screw. the phillips head is designed to "cam out" or torque limited, or in plain english: strip. for the purpose of not overtorquing the screw during installation. The japanese said to hell with that idea and made the edges straighter, deeper so theres a more solid engagement with the tool. thus JIS spec.
ALL the "phillips" head screws on a honda (and other japanese makers) are like this. thats why the screws in the distributor (or any where else on a 20 year old honda) strip like cheese. you can use a JIS driver on a phillips screw, but its not intended the other way around. and you can tell its a JIS screw because of the dot on the head. (go and look at the flatheads on the side of the car door, youll see.)
this is the proper tool for taking off those pesky rotor screws without stripping them.

or get the JIS bits http://www.ebay.com/itm/New-Vessel-JIS-431801-Replacement-Bit-Set-2400-2500-/380623444833?pt=LH_DefaultDomain_0&hash=item589eecdb61
after spending over $80 on new screwdrivers, i can tell you its worth it. particularly for a guy like me who really appreciates using the proper tool, and owning quality tools.
