readiescards Posted October 8, 2016 Share Posted October 8, 2016 Been buying screws. What is the benefit of single threaded screws over double threaded screws? Are they for different jobs/material? Thanks Link to comment Share on other sites More sharing options...
Construction Channel Posted October 8, 2016 Share Posted October 8, 2016 what screws ya been buying? i can't recall ever actually being told the difference or advantages but i would assume the twin threads go in faster but are more aggressive, 1 Link to comment Share on other sites More sharing options...
readiescards Posted October 8, 2016 Author Share Posted October 8, 2016 General wood screws from Screwfix and B&Q. Both seem to shoot on their packaging what style thread they are but no reason given why it was better than the other style. Link to comment Share on other sites More sharing options...
Construction Channel Posted October 8, 2016 Share Posted October 8, 2016 check a decent company like spax or reisser, they will probably have some good advertising schemes for both types Link to comment Share on other sites More sharing options...

Onoff Posted October 8, 2016 Share Posted October 8, 2016 My only contribution to the discussion is that I usually pilot EVERY hole still except when using plasterboard screws or SPAX flooring screws which are just amazingly designed things IMHO. 6x100 Goldscrews from S'fix - 5mm (long series) pilot. 5mm screws, 4mm pilot and so on. I countersink too. I don't generally hold with all this self cutting / no splitting spiel. In Contiboard or MDF edges I think a pilot is an absolute must to stop swelling/splitting. 3 Link to comment Share on other sites More sharing options...
PeterW Posted October 8, 2016 Share Posted October 8, 2016 Got one of these and I think it's great for pilot / countersink http://www.axminster.co.uk/axminster-turbo-drill-countersink-set-of-3-717964 1 Link to comment Share on other sites More sharing options...

Actually I quite like the Screwfix concept where you buy a metal case and keep it topped up. i bought my "Goldscrew" mixed case donky's years ago and I just top it up as and when I need it. its been thrown arround the back of the car, van, site and is pretty bullet proof. Of course i have have countless other boxes of screw n stuff. In fact shelves full of the blooming things. 2 Link to comment Share on other sites More sharing options...

I rate the Fischer screws and I've got the box from Screwfix that is topped up as and when it's needed. They appear on offer a lot so I tend to have a few spare boxes. I used to use Spax but they don't appear as easy to get hold of anymore and have on some of them changed to a Torx head - I get the reason why but I'm not going out and buying new screwdrivers just for one set of screws ..!

JanetE Posted October 9, 2016 Share Posted October 9, 2016 I've been using this countersinker http://www.screwfix.com/p/erbauer-plug-cutter-countersink-set-4-pieces/86253 it's a plug cutter as well but it's a good design because if the drill bit breaks you can just replace it. Twin thread screws are pretty expensive and like most everyone I can't see the point We've got one of those boxes from screwfix too, they work pretty well, though we do have quite a lot of the smaller screws left. Still you can always tip them out and replace with more sensible sizes. 1 Link to comment Share on other sites More sharing options...
Onoff Posted October 9, 2016 Share Posted October 9, 2016 (edited) The Screwfix case is great. I've topped it up on occasion with the Goldscrew Plus stuff when they've run out of the "normal" ones. Left the catches off a couple of times and dropped the lot! First time I managed to convince the youngest it was a game to sort them back into sizes but she's wise to it now! This is that Lidl set.....comes in a case. See how the drill bit flutes are weird: I tend to leave a PZ2 bit and holder along with a countersink bit in my Screwfix case. Also got a few of these type scattered around: http://www.toolsandfishing.co.uk/4-pce-pilot-drill-countersink--screwsink-drill-bit-set-792085-8562-p.asp Edited October 9, 2016 by Onoff 1 Link to comment Share on other sites More sharing options...

Depends on what I'm fixing. I always pilot drill in whatever. I don't always countersink. I might not countersink in softwood if using say Goldscrews but always will in ply, hardwood, melamine.

I haven't tried them, but GoldScrew Plus look interesting as they have the drillbit like feature that Spax have. No idea if it really makes a difference or is just marketing.

Only for hidden work and when I’m plugging stuff with wood plugs. Now use Reisser as I get them when they are on offer at TS or Howdens and are really good.
