There are only 4 threads in the Q8’s hole. If you put a stock screw in, the bald head bottoms out and you don’t even catch all 4 threads. If you grind the screw back, you have 4 full threads reaching to the bottom of the hole. That was my thinking anyway.
I've become fond of wrapping lights in paracord And am fairly sure you could add either a lanyard or make one with paracord . My first BLF Q8 got wrapped so fast I never really got to notice the flat spots or how the knurling felt . Nice thing is you can't go wrong .. just undo it and start again .
You guys have me thinking more about paracord options. There are a couple recessed milled circumference rings on the SP 36 that might work with a loop of cord and then using a knot, (PBWilson) splice or a braid to create an anchor point or extend a lanyard.
All the paracord I have is 550 or 750 (4-5 mm) which won’t drop down into the slots. The groove on the head is about 2.5 mm wide and the less recessed groove near the base (my preference) is 1.7 mm. It looks like 325 and 275 cord are around 2 mm and could be used for the top groove and for the bottom I could use 95 cord (1.74 mm) or maybe microcord (1.18) might work but probably too thin.
Maybe I will put in an order to Paracord Planet of Sgt Knots for a few shorter lengths of all of them and see if they work.
I would really like to see the wrap Boaz did and I just might wrap the hole thing and tie a lanyard off of that.
Use the self sticks that contain ball joint . Take apart and drill hole into ball boint. Run key chain ring through. Thread the 1/4 threaded end into flashlight. Attach lanyard.
Those could be found at 99 cents store BUT will cost 1.99 though
