Bags of 100 self tapping screws suitable N gauge track fixing, suit Fleischmann, Peco*, Mini Trix etc. free UK P+P.
The 6mm screws are suitable for fixing N gauge track such as Fleischmann, Peco and Mini Trix to a base broad. If you have 2mm of cork or underlay you might prefer the 8mm screws.. I would not recommend using unnecessary long screws, apart from the wasted effort your putting extra stain on the heads (greatly lessened if you pre drill a small guide hole).
FOR KATO UNITRACK you require the 10mm long screws, which I only have in black.
* Peco - For Peco N gauge set track it might be advisable to drill the hole a fraction wider, apparently these screws cause the plastic sleepers to stretch slightly and discolour.
Available with or without a screwdriver.
I also stock black N gauge screws various sizes for 00 gauge, please visit my Ebay store.
