M3.5 x 75mm Long Flat Countersunk Slotted Head Electrical Machine Screws, Mild Steel, Black Nickel, Pack of 10

These are ideal.I keep them on the van for when you get the odd accessory that just doesn't suit a standard screw as the originals were not long enough to reach the lugs in the back box, being 50mm long allows me to cut them down as necessary when I require.Overall, highly recommend.

I found it quite hard to buy a small pack of these at a reasonable price so was please to come across these. After having our walls plastered, the back boxes were mounted a little too far back for standard length screws. These saved the day! No messing around and the face plate was fitted easily. The black colour is great for coordinating with other fixtures.

I've only once needed electrical screws longer than 50mm (and could not immediately obtain any) so seeing these 75mm screws available via Amazon Vine I thought I'd order them, as useful to have for the next time or if wanting black screws. Could be carefully cut if too long.Although advertised as electrical screws they do not have the expected non-threaded tips and are flat-headed, so not ideal where the screws are exposed. Slightly convex screw heads look better. I have not yet used any but can confirm that they screw into 3.5mm nuts correctly. They are described as nickel-plated only on the packet, not the website but they presumably are plated rather than just a black nickel effect.At 55p each (£5.50/10 = 55p though website says 28p) they seem expensive but that seems to be the average price for this relatively uncommon length and colour of screw.

Dad has been modernising his living room and has had to use some deep boxes for new sockets, I was helping him out and he couldn't find any socket screws long enough, these are just the ticket. To be honest the grey finish doesn't fit with white sockets in my opinion, but that's personal preference and in our case we have screw covers to go over these anyway. Does exactly what they say on the tin, ideal if you're having to use deep boxes for sockets, RJ45 plates etc.

These arrived in a standard bag with a tag clearly showing length, size and quantity.The screws are well machined, with precise countersunk heads. The are no burrs, rough areas or damaged threads, just good quality manufacture.They are likely too long for many applications, but they are super easy to cut down as they are only 3.5mm thick. It's better to have this size that you can cut down, than being stuck with short versions that don't fit.I checked the dimensions with Mitutoyo calipers and they are spot on with the description. On a practical side, the fit perfectly on plug sockets and light fixings in the UK just to illustrate their use.Highly recommended.

I needed these as the screws you get with some back boxes are just too short. 10 screws for this price (5.50) is good value versus other back M3.5m in electrical store outlets. They went in clean with minimal fuss BUT I found 4 did not have a deep enough groove or a thick enough groove to get any purchase with a screwdriver without tearing the head. This means they are not for for purpose So hence 3 stars as then its 5.50 for 6 which is no real value at all.

I am shortly going to be retiling the wall under my kitchen cupboards and have decided, as no edges will be visible, that I will get a suitable tile adhesive that can be used to stick tile to tile and save the hassle of breaking off the old ones and then having to do some reparative plastering. This will mean that the electrical boxes for the sockets will be sitting quite deep under the new tile surface and so long screws are needed to fix the socket fronts to the boxes. These screws seemed like they would do just fine. Seventy five mm long would be just about an ideal length for my needs.When I received the pack I immediately tested them out on an electrical back box I had and I discovered that, whilst the threads seemed good and clean, the slot in the head for the screwdriver was not consistent from screw to screw. In about half the cases the slot was too shallow and narrow. These were totally inadequate to allow a good purchase of the driver which kept slipping off. I will not use these defective ones because, although I may manage to get them screwed in adequately, if I ever need to remove them then I could have a problem. The photo shows one of these screws (on the left) in comparison with a different brand that has an adequate screw slot.Value wise, at £5.50 for ten , they seemed reasonable but given half are throw aways that makes each screw £1.10 and that is not good value.
