Description & Specs

The Zenith M10 x 40mm hot dip galvanised hex head bolts and nuts come as a 25 pack, suited to general fastening that needs corrosion resistance. The hex head gives a firm grip for a spanner or socket, and a matching hex nut is included for each bolt.

  • Bolt size: M10 x 40mm
  • Pack: 25 bolts and nuts
  • Material: 4.6 grade steel
  • Finish: Hot dipped galvanised
  • Head type: Hex head
  • Colour: Grey

The short 40mm length suits thinner timber and metal joins in outdoor projects such as fences, gates and brackets where the galvanised coating helps prevent rust. Add M10 hot dip galvanised flat round washers for more bearing area.

Questions & Answers

What size are these bolts?

Each bolt is M10 with a 40mm shank, supplied with a matching M10 hex nut.

Are washers included?

No, washers are sold separately. M10 hot dip galvanised flat round washers pair well with these bolts.

How thick is hot dip galvanising?

It leaves a heavier zinc coating than electroplating, which is what gives the long outdoor corrosion resistance; thickness depends on the dipping process.

How many come in the pack?

This is a 25 pack of bolts with 25 hex nuts.

What grade of steel?

They are made from 4.6 grade steel.

Worth every cent

Did a lot of comparison shopping before buying here and I have no regrets. Best price I found anywhere and delivery was fast — 3 days to Melbourne. Product feels genuinely premium, not cheap at all. Packaging was solid too, box arrived in perfect shape. Will be back for more.
