Rated 5 out of 5 by from Great little screw although expensive these screws are grea. I have found the heads to be hard so they don't deform when using a power tool to drive them home. But the best thing is that they are stainless which means that they are fab fro use in kitchens, bathrooms and the outside where normal screws would rust.

Rated 5 out of 5 by from Great for outside use I've used these screws for years and been impressed with their cost and versatility. I now live on a coastal site and these are a must if you want to prevent those unsightly rust marks down your walls etc. If there was a criticism with them, it's that the heads are quite soft compared to the standard turbo gold screws so you need to keep the driver bit in good condition and straight. I would recommend these screws

Rated 5 out of 5 by from 4*40 utrascrew Great price, great product. Use the recommended 2.5mm pilot drill and you will have no problems with this screw but do remember it is only 4mm I diameter.

Rated 5 out of 5 by from A great value stainless screw. A great value stainless screw. Quick driving, and solid location of driver in head. Does what it says on the tin!

Rated 2 out of 5 by from Beware of Weakness I used these screws to secure timber fence pales to timber rails on a garden fence. That all went well. 2 years down the line I decided to reconfigure the fence. The screws have not tarnished or corroded at all but... the majority that I have tried to remove have sheared off just below the countersunk head so leaving a big problem. I'm going to have to rip the pales off the screw shanks. If your job may require screw removal in the future leave these well alone.
