Timbadeck Double Countersunk Stainless Steel Decking Screws 4.5 x 65mm 100 Pack is rated 3.5 out of 5 by 22.
Rated 2 out of 5 by from Poor screws Wanted something that would not rust away last screws where green outside ones but most had rusted away.the stainless looked a good option but they are not very strong and can snap or the bit just rounds them.the only way I could get them to do the job was drill a hole in the decking first.

Rated 3 out of 5 by from Not great for the money This review is for the stainless version, I’ve used the green ones and not really had a problem but using the stainless with an impact driver I found them to be quite soft and the heads strip easily. Given that they cost more unless you really need stainless I would leave them well alone or make sure you have some screw extractors with you for the ones where the heads strip before they are fully home.

Rated 3 out of 5 by from OK if you are careful On the plus side, they are stainless, so no rust, and they drive happily through 34mm decking with no pilot hole. That's important when you are putting several hundred screws into decking. However, the cross head is shallow, so my bit keeps slipping unless I push down really hard. And in the first 100 screws, 3 of them bent as I tried to power them in. Never had that happen on a screw before! The screws that I got from the specialist fencing supplier were slightly more expensive, but better in all respects.

Rated 4 out of 5 by from Stainless Steel Decking Screws Really good value for stainless. At this price why bother with carbon steel? I don't know what some other people are doing with these but out of a pack of 500 I only had 2 failures, and I think that was because they met some noggin screws. If you drill pilot holes, like you should, and use a driver with a torque limit, you shouldn't have any problems.

Rated 5 out of 5 by from timbadeck 4.5 x 65mm s/s screw having to replace some decking boards and struggling to get the existing rusty screws out I turned to these. They are plenty long enough to hold down the 28mm decking boards and were a dream to use. They penetrated the wood and ran in true with a positive grip, and of course they will never Rust. VERY PLEASED.

Rated 1 out of 5 by from Poor quality Can't believe they're not butter. Don't normally slate a product but these are the worst quality screw I have used from screwfix. First one snapped because I didn't drill a pilot hole,ok, so pre drilled all screw holes, screw driver set to low torque setting and infrequently rounded off the heads like it was warm chocolate. Two more snapped, even with pre drilled hole. Avoid these screws, there are plenty of decent ones at screwfix.

Rated 5 out of 5 by from worth the cost Got these screws a number of years ago for my decking. When relaying it this year, these screws are just like new. They went in shiney and sharp and they came out shiney and sharp. Ive reused them and bought some more for the additional work ive got to do. Cross head is good and strong, doesnt round off if you use the correct bit. Although it suggests pre drilling the pilot hole, i just screw straight through the decking without any issue's .

Rated 2 out of 5 by from Too fragile and inconsistent Good value for Stainless Steel, but: * Quality control is poor - I found several screws with bent shanks * I know SS is soft - but these are very fragile. I only had a 3mm bit to hand for the pilot holes but was using very soft wood (cedar). About 10% of the screws broke off at the head. * If you use these - then drill a full length 3.5mm pilot hole, Make sure you drive them straight and never try to re-use a screw that you have just unscrewed. They break about twice as often if you try to tighten them twice. Would not buy again.
