Where to get left hand thread bolts?

Anyone know where i can get a left hand thread M8 allen bolt from? I want to fit my sat nav where the old mirrors went on my bike but its a left handed thread

Clerkenwell screws is your best bet.

get a longer one and cut to length.
Add a grip washer at both ends and lactate. Did the same for my camera.

You lactated & filmed it? :crazy:

PMSL :laugh:

Cheers for the help guys but i went another route… Couldnt find anywhere with a left hand thread boltup here but plenty with left hand thread nuts… Whats that all about?

Anyway instead i used a heli coil to make the mirror mount M8 from M10… Was going to drill out the adapter and rethread it to use the heli coil but turns out it was a perfect fit in the mount :smiley:
