Ric Posted September 17, 2019 Share Posted September 17, 2019 Hi Guys and Gals, I've fitted some new seats and although they are fixed down well i think i'd be happier with some longer bolts. Does any body know what kind of bolts they are? It's not quite m10 could be m11 with a weird Japanese thread. Anybody with a definitive answer?

evinX Posted September 17, 2019 Share Posted September 17, 2019 Get yourself a bolt thread pitch measuring guage. Looks like a feeler guage. 2 or 3 quid of ebay mate. Worth every penny to someone who works on their car Link to comment Share on other sites More sharing options...

zap Posted September 17, 2019 Share Posted September 17, 2019 Will be M10 x 1.25 pitch, could be either a 14mm A/F or 17mm A/F spanner size depending on positioning. Good tip evinX. Link to comment Share on other sites More sharing options...
