Frequently asked questions

When should I use 10mm instead of 8mm flat bar?
Use 10mm where the bracket or support will carry significant loads or where rigidity is critical. For lighter-duty brackets and panels, our 8mm or 6mm options are more than adequate.

Is it weldable?
Yes — fully weldable with MIG, TIG, or stick. Browse our full flat bar range.

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.
