Casing bolt screw size length

[wayne]

Thinking about replacing screws with Stainless Steel? A list I made when putting together SS kits for friends.

Please keep in mind this list was for my personal use so don't get upset about my use of "Phillips" (I've already heard from the JIS crowd on another forum ; ). For your interest, a note from Colin Packer on FB. Colin has demonstrated before detailed knowledge of part numbers and other things Suzuki so I found this very useful especially if you're being hounded by JIS fanatics re your VJM ; ) Here he's explaining the Japanese change from JIS (Japanese Industrial Standard to ISO (International Organization for Standardization) when related to the 6mm "phillips panhead" screws on the RE5. The dot he refers can be seen in the 2nd photo, the two on the right are original RE5 exhaust shield screws, the one on the left also 6mm but with the ISO "dot"-

I replaced bolts on a built with stainless a few years ago and spent hours removing the lettering off the heads first . It just didn’t looks rite with “A2” imprinted on the heads .
Also take care in replacing the washers as stock replacements are too wide and done fit in recesses .

Agree, doesn't look right. I've seen the ones with lettering. I sourced mine from Singapore and fortunately, no lettering.

Your comment about over the counter washers being too large- reminded me, had an RE5 sent over which had numerous faults. One of the interesting ones was a crack in the alternator casing. Guy restoring it used Stainless phillips pan heads sourced in Australia and at the time, they had a larger head diameter than stock. As it was screwed into the well in the alternator case, the head put so much force on the sides of the hole it cracked the casing (and had gone unnoticed).
