Bolt Action Set Screw

[Troy Cole]

Wondering if anyone knows what size the Phillips set screw is on the PSI bolt action pen? Thanks

The one that fits from my Precision (cheap) Screwdriver Set is #0.

I use a #1 and it works well.

In thinking he means the actual screw? Threads and length. ?

Troy, If you're you're looking for dimensions, I measured 2.5mm dia x 10mm len. Don't know where my metric thread gauge is but I suspect it is metric, maybe standard for a 2.5mm.

My apologies, should of been more specific. I'm actually just trying to find out what size of screwdriver tip, i.e. (0,00,000). I tried to tighten one of these screws with a screwdriver I already have (not sure of the size), and it seems to be stripping the head on the set screw. I can't seem to be able to get the set screw tight enough to keep the bolt handle from spinning. Thanks Again
