Well Pete, I must say, an excellent thread. I'd never heard of JIS drivers till I spotted your thread. Thought all crossheads were Philips. How wrong can you be eh?! And me being an old git too!! Should know better. Cheers for the advice, will pick up a set. Mind, I tend to swap out all screws for socket head capscrews where I can, as I much prefer them.
Oh yes Manny - I always prefer SHCS too but for authenticity sake, the JIS screws are good and if you use the correct driver, they will take torque just about as well as a good socket head cap screw.
