Twigman Posted October 8, 2015 Share Posted October 8, 2015 (edited) I tried to setup my JV the other day. One small problem One of the 8 saddle height screws was so rusty that the screwdriver took the top off the screw - they're slotted rather than allen keys in true vintage style. Does anyone know whether the thread is imperial or metric and where I can source a replacement saddle height screw (or 2 or 3) ? It's a 1983/4 JV export 62 P with the threaded saddle bridge and slotted saddle height screws. Imperial or metrc thread?

franzbassist Posted October 8, 2015 Share Posted October 8, 2015 I had the same problem. Look [url="http://basschat.co.uk/topic/162862-grub-screws-for-a-1988-mij-p-bass/"]here[/url]! Quote Link to comment Share on other sites More sharing options...
Twigman Posted October 8, 2015 Author Share Posted October 8, 2015 I could get these: http://www.allparts.uk.com/products/bridge-saddle-height-screws-for-bass-hex-head-metric-10mm but ideally i'd like ORIGINAL slotted screws. Allparts only do imperial slotted screws..... I vaguely remember the JV series were rumoured to be assembled using American hardware shipped over to japan...if this is true then my thread will be imperial, won't it? Does anyone know for sure?

ikay Posted October 8, 2015 Share Posted October 8, 2015 You can buy slotted metric grub screws from here but min quantity is a box of 200 - [url="http://www.avonstainlessfasteners.co.uk/misc-stainless/slotted-grub-screws-flat-point-m3-m10-a4-din551"]http://www.avonstainlessfasteners.co.uk/misc-stainless/slotted-grub-screws-flat-point-m3-m10-a4-din551[/url] There's a good chance that yours are imperial slotted screws anyway as most metric ones are hex. Here's a quick way to check. Vintage US Fender slotted screws have UNC 6-32 thread which is the same as the long saddle intonation screw. Try removing one of the intonation screws and see if it fits the height adjuster thread. If it does then it's likely the whole bridge assembly is imperial and the vintage slotted screws should work.

MoonBassAlpha Posted October 8, 2015 Share Posted October 8, 2015 I've got a fair few M3 hex stainless set screws you can have if they do turn out to be metric. No rust issues on these little chaps! Quote Link to comment Share on other sites More sharing options...
