The screws are made from steel with a bright zinc-plated (BZP) finish for general corrosion resistance, and are driven with a hex (Allen) key rather than a screwdriver, which lets more torque be applied without cam-out.\u003c\/p\u003e\n\u003cp\u003eThis hex socket confirmat screw is designed for joining wood, wood-based panels and furniture construction boards. The hex socket simplifies and speeds up assembly with a hex key, the optimised thread allows efficient installation, and the finished joint offers excellent strength and stability. Four sizes are available, 5.0 x 40mm, 5.0 x 50mm, 6.4 x 50mm and 7.0 x 50mm, in packs of 10, 50, 100 or 250, so the same MDF screw covers anything from a single cabinet to a full run of units.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBroad unthreaded shoulder acts like a steel dowel beneath the head, locking panels together and resisting the racking movement that loosens standard wood screws in chipboard or MDF\u003c\/li\u003e\n\u003cli\u003eManufactured from steel with a bright zinc-plated (BZP) finish for general corrosion resistance\u003c\/li\u003e\n\u003cli\u003eHex (Allen) drive accepts higher torque than a screwdriver slot, reducing the risk of cam-out during assembly\u003c\/li\u003e\n\u003cli\u003eAvailable in shank diameters from 5.0mm to 7.0mm (0.20-0.28in) and lengths from 40mm to 50mm (1.57-1.97in) to suit different board thicknesses\u003c\/li\u003e\n\u003cli\u003eFlat countersunk head seats flush with the panel face when driven into the correct stepped pilot hole\u003c\/li\u003e\n\u003cli\u003eOptimised thread for efficient installation, giving excellent strength and stability of the connection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eShank diameter\u003c\/th\u003e\n\u003cth\u003eLength\u003c\/th\u003e\n\u003cth\u003eHead diameter\u003c\/th\u003e\n\u003cth\u003eHex drive size\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e5.0mm (0.20in)\u003c\/td\u003e\n\u003ctd\u003e40mm (1.57in)\u003c\/td\u003e\n\u003ctd\u003e7.5mm (0.30in)\u003c\/td\u003e\n\u003ctd\u003e3mm (0.12in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e5.0mm (0.20in)\u003c\/td\u003e\n\u003ctd\u003e50mm (1.97in)\u003c\/td\u003e\n\u003ctd\u003e7.5mm (0.30in)\u003c\/td\u003e\n\u003ctd\u003e3mm (0.12in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e6.4mm (0.25in)\u003c\/td\u003e\n\u003ctd\u003e50mm (1.97in)\u003c\/td\u003e\n\u003ctd\u003e9.5mm (0.37in)\u003c\/td\u003e\n\u003ctd\u003e4mm (0.16in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e7.0mm (0.28in)\u003c\/td\u003e\n\u003ctd\u003e50mm (1.97in)\u003c\/td\u003e\n\u003ctd\u003e10.5mm (0.41in)\u003c\/td\u003e\n\u003ctd\u003e4mm (0.16in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eTypical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eConfirmat screws are the standard fixing wherever engineered board panels are joined face-to-edge or edge-to-edge in a 90° carcass joint:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eKitchen and bedroom cabinet carcasses\u003c\/strong\u003e - joining side panels, bases, tops and shelves in chipboard or MDF, where the shoulder's resistance to racking helps keep corners square under the repeated door and drawer use a carcass sees.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWardrobe and bookcase assembly\u003c\/strong\u003e - larger panel joints that call for a mechanically strong, glue-free fixing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOffice furniture and shop fittings\u003c\/strong\u003e - desks, cupboards and modular fittings built from chipboard or MDF panels that need a fast, reliable knock-down joint.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGeneral DIY shelving and storage units\u003c\/strong\u003e - any home-built unit in chipboard, MDF or particleboard where an ordinary wood screw would be prone to working loose in the board's low-density core.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWooden structures and fittings\u003c\/strong\u003e - other projects that need solid, durable connections between wood and wood-based panels, chosen by professionals and DIY enthusiasts alike, for both indoor and outdoor applications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Guidance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eConfirmat screws need a stepped pilot hole, not a plain drilled hole.
