A2 (304) stainless steel fasteners specified for indoor use - the grade that gives you full corrosion resistance in normal room and workshop conditions without the price uplift of marine A4 (316). Machine screws, socket caps, hex bolts, dome nuts, nyloc nuts and Form A washers - every product in the Simfix indoor range is stocked in A2 (304) as standard.

For bathrooms, kitchens and any humid interior environment, upgrade to the A4 (316) range. Trade packs of 50 across common sizes, DIY packs of 10 for one-off jobs. Free next-day UK delivery on orders over £50, 30-day returns.
