Rated 4 out of 5 by from This screw is for turning Needed to screw a faceplate onto a yew wood turning blank. These screws were perfect, no pilot hole required so no risk of over drilling and the single thread design gives a very secure hold on the wood which is essential when it is spinning at 1200rpm. With a box of 200 at this price there is no concern about replacing them frequently on new projects

Rated 4 out of 5 by from Very good, but not exceptional The screws are great value & hold the wood I screwed superbly. When using a manual screwdriver they are superb. My only minor quibble is that when I used a low speed drill with a screwdriver attachment the screw heads sometimes were too soft & the drill spun. I used different drill heads sizes, but nothing worked :-( I have never had this issue with other Screwfix screws. Overall I would still rate this product positively :-)

Can you use thses screws outside, as in do they rust, need to use on roof, thanks.
Asked by: St3v375
Hello, The screws are corrosion resistance, but not corrosion proof. Meaning, that eventually, these screws can rust. If you'rE using on a roof outside I would recommend opting for a screw that is corrosion proof, like a stainless steal screw. Alternatively you might wish to consider a screw cover or perhaps applying a sealer over the screws to protect them from water. I would advise contacting a competent tradeperson for further information and product recommendations. Thanks for using Q&A. [DG]

Would these be a suitable screw for chipboard?

Asked by: Asshhh
Hello, These should be fine to use with chipboard, though I would not avoid using them close to edges (splitting might occur). If you're planning on driving close the edge you might want to look for a screw with a rifled shank (the turbo range of screws we sell have these) These screws whilst corrosion resistance, are not rust proof. Depending on where these screws will be used it might be better to opt for a stainless steel/outdoor screw (like the ultra screws we sell). Thanks for using Q&A. [DG]

Are these screws zinc plated?

The description for these screws is 'corrosion resistant' - does this mean that they are zinc plated? Or just wax coated.
Asked by: Blinkspeed
Hello, These screws are only wax coated and do not have a zinc coating. Thank you for using Q&A.
