Simfix hexagon flange screws to DIN 6921 in A2 (304) stainless steel. The integral flange under the head distributes clamping load over a wider surface area, removing the need for a separate washer and giving a cleaner, faster fit.
These are the non-serrated variant - ideal for finished surfaces, panel work and assemblies where the underside of the flange shouldn't mark the substrate. M6 and M8 thread sizes stocked, in DIY packs of 10 and Trade packs of 50. Free next-day UK delivery on orders before 4PM, no-quibble returns on every order.
