I noticed when not using the flush mount snaps, the screw for bolt locked items was too short. So I remodeled and extended the threads by 6mm. this makes the overall length 15mm, and the pegs i was trying to attach had a 10mm depth. so these should work as long as you are using the raised snaps, and have 10mm of depth in your peg or support or whatever youre trying to bolt lock.
