The 3.5mm diameter thread matches the standard mounting holes on UK faceplates, switches, sockets and modular accessories, while the 75mm length allows the screw to pass through the accessory, through the mounting frame, and into the back box lugs with enough thread engagement for a secure fixing.\u003c\/p\u003e\n\u003cp\u003eThe raised countersunk head sits flush with the faceplate surface when driven in, eliminating screw protrusion on wall-mounted accessories. The nickel finish provides corrosion resistance in typical indoor environments and matches polished chrome, brushed chrome and steel-finish faceplates. Sold in packs of 100, the quantity covers approximately 12-16 dual-gang accessories or 25-33 single-gang accessories depending on the number of mounting points per plate.\u003c\/p\u003e\n\u003cp\u003eThese screws are a direct replacement for the fixing screws supplied with Knightsbridge and most other UK electrical accessory ranges. The M3.5 thread is the UK standard for electrical accessory mounting, so these screws are compatible with back boxes, grid frames and mounting plates from all major UK manufacturers. The 75mm length is longer than the typical 40mm screw supplied with most accessories, making it suitable for deep back boxes, stacked mounting frames, or installations where additional mounting depth is needed.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e3.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e75 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_2488023_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are these screws used for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThese screws fix electrical faceplates, switches and sockets to UK back boxes and mounting frames. The M3.5 thread is the UK standard for electrical accessory mounting, so they fit all major brands of UK electrical accessories.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy would I need a 75mm screw instead of a standard 40mm screw?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 75mm length is needed for deep back boxes, stacked modular grid frames, or installations where the accessory sits further from the wall surface. Most single accessories use 40mm screws, but 75mm screws are required when additional mounting depth is present.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow many screws are in a pack?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe pack contains 100 screws. This is enough to fix approximately 25-33 single-gang accessories or 12-16 dual-gang accessories, depending on the number of mounting points per faceplate.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre these compatible with screwless faceplates?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. Screwless faceplates use a separate sub-frame that fixes to the back box with screws, and then a cover plate clips onto that frame without screws. These screws would be used to fix the sub-frame to the back box, but the cover plate itself does not use screws.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":45293780926731,"sku":"CSCREW75","price":6.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/158856_35206abd-e8e1-4074-ae87-e007daacc309.jpg?v=1714664036","url":"https:\/\/niori.co.uk\/products\/m3-5-x-75mm-raised-head-countersunk-electrical-screw-nickel-100-pack","provider":"Niori","version":"1.0","type":"link"}
