Jbob Posted June 23, 2018 Report Share Posted June 23, 2018 This is a long shot but..... I have a builders dumpy level in the shed and an aluminium tripod that goes with it. What I want to know is, what size is the bolt that holds the level to the tripod? I have alternative plans for the tripod but don't want to destroy the level to use the base. I measured the bolt across and it's 12-13mm (including threads) but the thread doesn't look fine enough to thread into a standard bolt. Hope someone may have one or used one and know the thread type.

Jbob Posted June 23, 2018 Author Report Share Posted June 23, 2018 Brill thanks for that. Used a level so many times but have never needed to know the bolt size. Quote Link to comment Share on other sites More sharing options...
figgy Posted June 24, 2018 Report Share Posted June 24, 2018 Nor have I, but google had it in 30 seconds. Along with camera tripod 1/4” thread.

mowdy Posted June 24, 2018 Report Share Posted June 24, 2018 Do you mean a split. Prisum level ( dumpy level ) as they generally sit on a 1/4” pin or a site level tripods that takes a 5/8ths threaded bolt ? Quote Link to comment Share on other sites More sharing options...

Mowdy, it's definitely not a 1/4" pin. 5/8 bolt that screws into the bottom of the level. Quote Link to comment Share on other sites More sharing options...
mowdy Posted June 24, 2018 Report Share Posted June 24, 2018 (edited) So a sight level trip pod aka theodolite ?not a dumpy level then as they sit on a pin and use a split screen prismatic lenses very old school but they still work Edited June 24, 2018 by mowdy Quote Link to comment Share on other sites More sharing options...
