#113668 PapaTom (User) Have Star - Will Travel Platinum Boarder Posts: 1369 JIS screwdrivers 2 Months, 3 Weeks ago   I've been reading about the stripped float bowl Philips heads screws for some time now on the forum (and others), and found we've been using the wrong kind of drivers. The screwdrivers we should be using are JIS (Japanese Industrial Standard) drivers, which are not made to intentionally strip the head of the screw (thereby saving the screw's threads instead), as the Philips was originally made to do. Our toolkits contain the JIS driver bits. I found a good set of drivers at http://www.rjrcooltools.com/shop_item_detail.cfm?subcat_ID=65 and bought a set of Vessel stubbies and a couple of longer-shank drivers. And, boy, do they work great. They lock into the slots and don't even try to twist out. Another website that sells them is http://www.ikaswebshop.com/hojisscset4d.html I didn't know if this was common knowledge, but I don't remember reading anything about this in the forum.   Logged     Last Edit: 2008/08/28 21:02 By PapaTom.   FREE SPIRIT 2007 Silverado   The administrator has disabled public write access. #113673 Mark7 (User) Look for me on MSN chat if you want.

Hey Tom next few folks you see fixing to tear into their carb for the first time suggest they use Yammys driver and if it does not bugger the head you prove your point...Coug   Logged       The administrator has disabled public write access. #113819 Helmut (User) If you can't be young be immature Senior Boarder Posts: 350 Re:JIS screwdrivers 2 Months, 3 Weeks ago   yeah that is right PAPA. The Vessel drivers are at a slightly different angle to ours. In fact they actually work better on all Phillips screws. We use them exclusivly in the maintenance dept at the Japanese auto plant I work in. Funny I never really made this connection though.   Logged       The administrator has disabled public write access. #113870 Akela (User) Ephesians 1:4-5 Junior Boarder Posts: 153 Re:JIS screwdrivers 2 Months, 3 Weeks ago   I have three large Phillips screwdrivers in my toolbox, each bought from a different bargin bin in a different hardware store, and each with slightly different angles on the tip. If I find a screw thats hard to move, I try all three on it to find which one has the least slop before trying to turn it. My stragegy is to buy screwdrivers out of the bargin bin at hardware stores rather than pre-packaged sets because I think they overcharge for them. That way I can afford a dozen of all different shapes and sizes for the price of 3 Snap-Ons ...   Logged     The administrator has disabled public write access.
