Frequently asked questions
Do I need a washer with a flange nut?
Not usually — the integral flange acts as a built-in washer. This makes flange nuts faster to fit and ideal for production environments.
Do you stock other sizes?
Yes — browse our full flange nut range in M6, M8, M10, M12, M16, and M20.

Complete your order
Northern Fasteners stocks everything you need for a complete, matched assembly. Always pair your fasteners with the same finish throughout — BZP with BZP, HDG with HDG, A4 stainless with A4 stainless — for consistent corrosion protection and a professional result. Browse our full range of hex nuts, washers, threaded rods, and bolt and nut sets to find everything you need.
BZP, HDG or A4 Stainless — which finish do you need?
Choosing the right finish is just as important as choosing the right size. BZP is ideal for indoor and sheltered use. HDG provides heavy-duty corrosion protection for outdoor, structural, and timber applications. A4 Grade 316 Stainless is the choice for marine, coastal, and chemical environments where no rust is acceptable. Read our guide to help you decide.
