Timbadeck Double Countersunk Stainless Steel Decking Screws 4.5 x 85mm 100 Pack is rated 1.9 out of 5 by 12.
Rated 4 out of 5 by from TIMBADECK STAINLESS SCREW Used these screws as at 85mm just right for fixing 50mm Kooltherm insulation direct on to underside of rafters with insulation washers. They grip well and are stainless so would recommend for applications where moisture may be an issue.

Rated 1 out of 5 by from What a pile of rubbish I was joining 2 50x50 treated CXLS together, the first screw out the box bent and stripped the head using a standard drill / driver. So I abandoned those and used spax Wirox screws with no issues. I took the rest of the box back

Rated 1 out of 5 by from ABSOLUTE RUBBISH Bought these for a decking project where the client insisted on using non corrosive stainless screws. I used about 200 of these and more than 10% of these had to be removed due to the heads rounding off or the actual screw buckling when fitting. Used dewalt impact driver but then switched to dewalt drill with low torque to see if made any difference.........nope - still absolute rubbish. Don't buy these is my advice, they are not fit for purpose and an absolute pain to use.

Rated 1 out of 5 by from Too weak for the job Too many were weak and sheared, bent or broke off partway through for the job (fixing timber joist for decking). I was recommended to get s/s for tanalised wood. Not sure if this bunch of screws were tempered?

Rated 5 out of 5 by from Canny screw These are canny screws. They are made of stainless steel. They are the size that it says on the box. They go in drilled holes. They go into wood that is not drilled. You turn them with a screwdriver. They tighten up. It is amazing - they do exactly what you would expect a wood screw to do. How am I doing, guys - 8, 9/10? Come on - I'm working hard... Screws, stainless, steel, use with wood. That's it. Mind you - good price.

Rated 1 out of 5 by from rubbish Bought these to hold decking , I will need to redo the lot, load of rubbish round out at the first sign of tightness and bend very easily worst product I have ever bought out of any hardware store

Rated 1 out of 5 by from not good Bought these to assemble a new deck. Wish I'd read the reviews before purchasing as these are a load of rubbish. They look good but are too easily bent and the heads round off too easily even if you pre-drill a pilot hole. Threw the lot in the bin.

Rated 1 out of 5 by from Very Poor These screws are made from cheese! Bend, strip and don't pull timber together. Pay a little more and get a much better screw elsewhere.
