Ultra Screw PZ Double Countersunk Woodscrews 4 x 50mm 200 Pack is rated 4.4 out of 5 by 11.
Rated 4 out of 5 by from Good screws well defined PZ drive provides positive interface to the drive head. Threads are well defined also. These are A2 stainless which has a lower grade of corrosion resistance to A1 standard. However my experience of these is that have excellent corrosion resistance even in sea side environments. There is nothing worse that rusting fasteners !!

Rated 5 out of 5 by from Stainless Steel Screws I always use stainless steel screws for exterior work as I hate to see the eventual rust marks of other types of screws. These screws were ideal for my new fence.

Rated 5 out of 5 by from Signs on wall. Bought these to fix signs on the wall. Was looking for somthing rust proof, hence the reason for Stainless Steel screws. I did shear 1 head off the the point I had to angle grind it back. I guess you will always have that handful of screws which will not do the job. Other than that, screws in nice, 98% heads stayed in tack and cant complain.

Rated 5 out of 5 by from 20 Years on Carport Replaced the screws for corrugated plastic roofing sheets with these, removed old sheets to replace - no problems. Virtually no rust, slight discoloration, two out of fifty had rusty heads but still held screwdriver bit.

Rated 4 out of 5 by from A good screw I was building a three step box using decking material left over so I could reach gutters on my conservatory without putting up a ladder that might mark the window frames. These stainless screws were used as the "step up box" will be left out in the weather, no pilot holes needed, they just wound into the softwood with my battery drill, excellent.
