I had a set from the chap who does the trigger jobs - Eric Brooks - and they seem fine.

I've got Eric's screws on my brno and my cz hmr.
They're much easier to remove with a good quality allen key rather than trying the old screws with an inappropriate screw driver.
Keep the old ones in case you decide to buy some lovely snap on drivers.
slow is smooth smooth is fast
I used a set from Eric, then matched them form engineers supplies, good quality and with a decent allen key or bit you wont get any problems
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)
At £60 to £70 each these are not cheap, but in the end are worth it.
