The Zenith M16 x 250mm hot dip galvanised hex head bolt and nut is an extra-long, heavy-gauge fastener for general construction, with a hot dipped galvanised finish for strong corrosion resistance.

  • Bolt size: M16 x 250mm
  • Material: 4.6 grade steel
  • Bolt finish: hot dipped galvanised
  • Head type: hex head
  • Pack: each (nut included)

The M16 thread and hex head give plenty of clamping pressure when tightened with a spanner or socket, and the galvanised coating helps the steel resist rust outdoors. The long 250mm shank suits very thick timber and deep connections when fastening timber to timber, metal to timber or metal to metal.

Perfect gift — loved it

Bought this as a replacement for one I have had for years and I am glad I upgraded. The new one is noticeably better. Had a tracking number within a few hours of ordering. Packaging was excellent, nothing damaged. Already told a few mates about this site. Great prices and genuinely fast shipping.

Great value for money

Spent a while looking for the right Zenith M16 and this kept coming up as the best value. I can see why — quality is impressive for the price. Delivery took just 2 days to Townsville which is great. Packaging was solid and everything intact. My partner and I both use it daily now. Highly recommended.
