onelesscharlie Posted December 9, 2010 Report Share Posted December 9, 2010 Hi Sorry if this has been covered before but could anyone confirm the ring clamp screws on optilok rings. I think that they are m3.5 x 0.6 x 7 with a turned down head. thanks Colin Link to comment Share on other sites More sharing options...

fizzbangwhallop Posted June 23, 2013 Report Share Posted June 23, 2013 Definitely a 3.5mm hex driver required (Found one in my security bits set bought from Screwfix donkey's ago - 16 bits and a small extension type of thing) Head diameter is 4.89mm Head depth is 2.89 Thread is 7mm long But I couldn't tell you the pitch. Cheers Fizz Doh! 2.5 NOT 3.5!! Link to comment Share on other sites More sharing options...
JC275 Posted June 23, 2013 Report Share Posted June 23, 2013 I recently bought some replacements from eblag, seller was in the US but the sale went very smoothly, I think that I paid about $22 Inc postage. Link to comment Share on other sites More sharing options...
