I belive the Brooks screws are made by Derek Niles however I went for the P&J Custom Products ones as Eric Brooks deliveries are at best inconsistent...
At 60 inch lbs stronger.

Update on the bolt spring for my CZ .22lr Varmint from tJ&P Custom products http://www.jnpgunsprings.com/ that I bought & started this thread.
Went to the farm to day with my 13 year old son (he uses my AA S410) I sighted in before I started to shoot, last time out I was shooting 300 yards at the range, needed adjustments. At 50 yds prior to fitting the spring a nats under 1/2" 5 shot group today 1/4" to 3/16" might be me but the CZ felt crisper, possible quicker lock time, though I usualy work in hours not milliseconds so cant say for sure.
All in all money well spent.

I bought a set from Eric Brooks for my 17HMR but never got round to fitting them, sold it recently and bought a .22 Varmint. I've ground one bolt down and they fit, the finish is a mat grey and matches the Cz trigger guard. I found the standard Cz screws had very thin slots and were easy to chew up, infact my rifle was brand new but one of the screw heads was marked slightly (a blind man on a galloping horse would be glad to see it though, it wasn't much of a mark)
I should be making swarf!
At £60 to £70 each these are not cheap, but in the end are worth it.

I quite agree, however they are not torque wrenches and action screws on CZ's need torquing to be consistant...Originally Posted by u.k.neil

Not if they are properly bedded on pillars
And bedding three rifles is much cheaper than paying out for a torque driver (yes i'm cheap)
I think the J&P screws and spring are well worth the money.
And for the nay sayers, a rounded off cheap allen bolt is much easier to drill out then a slotted screw, and no special jig is needed
