Frequently asked questions
What's the difference between A2 and A4 stainless?
A2 (Grade 304) is standard stainless steel suitable for most corrosion-resistant applications. A4 (Grade 316) contains molybdenum, giving it superior resistance to chloride corrosion — making it the right choice for salt water, coastal, and chemical environments.
What's the spanner size?
17mm A/F (across flats).

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.
