Rated 5 out of 5 by from Quality Screws It has to be said, the old saying "you get what you pay for" is especially true when it comes to these screws. Yes they are a fair bit more pricey than most silver coloured alternatives, but the second you start using them you will understand why. They are far less prone to head damage when using a drill or impact driver and go into unpiloted wood quickly and easily with splitting being a rarety. The design of the thread also eases a lot of stress from tools.

What size rawl plug is best for these?

To be used in 14N concrete blocks
Asked by: SHW60
Hi SHW60, The Fischer SX Nylon Plugs 6 x 30mm 100 Pack (Product Code 98684) can be used with 4mm screws. However, it is important to select the correct length as Fischer say that with this plug the screw must protrude from the end by around 5mm for it to work properly, so plug length would be screw length plus fixture thickness minus 5mm. It may be worth asking Fischer about this at technical@fischer.co.uk Thanks for using Screwfix Q&A. JT

Are these suitable for external use, eg fencing?

Asked by: JB71
Hello jb71 These would be suitable for exterior work but they are not stainless steel so would be susceptible to corrosion. Thanks for using Q&A
