Quicksilver Woodscrews Roundhead 6ga x 5/8" 200 Pack is rated 3.8 out of 5 by 15.
Rated 5 out of 5 by from Quality woodscrews When looking for screws /fixings of any kind I always refer to my Screwfix catalogue. I can usually find what I require in there. I buy my c/s screws in bulk from yourselves but I specifically wanted a round head so I bought this box. They are very good quality and do the job required , and the price is as always unbeatable.. I always recommend Screwfix to my friends.

Rated 5 out of 5 by from Great value Why would anyone buy screws anywhere else. Boxes of 100 or 200 for a fraction of the cost for little packaged packs of 20 everywhere else.

Rated 1 out of 5 by from Rubbish - A Real Zero-Star Product! I bought several boxes of these screws and only still have them because I'm too tight to throw them away. The heads cam out every time unless you drill a pilot almost the same size as the screw or use over-large wall plugs - even lubricating them doesn't help much. A total waste of time and money...

Rated 4 out of 5 by from Nice easy screw Good sharp tip aids a quick pick up and easy to drive home. Great first time application and no issues with heads snapping or camming out. Fully recommended

Rated 5 out of 5 by from Great screws Excellent product and great price. I've used loads of this range over the years. Pity Screwfix don't stock a wider range of sizes - length is often critical with roundhead screws.

Rated 3 out of 5 by from Decent screw Decent enough screw for a good price. Used these to hang brackets for kitchen wall cabinets and did the job as required.

Rated 4 out of 5 by from Check what's in the box Needed some roundhead screws for outside work so checked the reviews and went for these. The screws are absolutely fine, you need a good driver to send these in, preferably an unused bit. I probably should have drilled pilot holes first but although they took some pushing, I didn't get any snapped heads. The main problem, as noted by other reviewers, is that they are supplied in a box with a countersunk picture on the outside. I bought the box and thought nothing of it until I opened it and found --200 countersunk screws. I had to go back and change the box which again had a picture of countersunk screws. This time I opened it in store and found the correct roundhead screws inside. What a waste of time and petrol. You need to sort this out Screwfix.

Rated 2 out of 5 by from Not easy. Countersunk screws have plenty of metal into which to shape the Pozi recess. Raised heads don't. Driving these into even quite soft wood with new (good quality) bits was a real struggle. Compared to screws with a nice deep recess, which fit nicely onto the bit, they were horrid, taking extreme pressure to keep the bit engaged. Not really the screw's fault, since an adequate recess would leave so little metal that the heads would snap off. However, if you don't really really need raised head - really really don't use these.
