The Zenith M8 x 100mm Hot Dipped Galvanised Cup Head Bolt and Nut is a single 4.6 grade steel coach bolt for timber and metal fixing.

  • Bolt size: M8 x 100mm
  • Head type: Cup Head
  • Material: 4.6 Grade Steel
  • Finish: Hot Dipped Galvanised

The square neck under the domed cup head bites into the timber to stop the bolt spinning as you tighten the matching nut, giving a secure fit. At 100mm long it reaches through thicker sections, and the hot dip galvanised coating adds corrosion protection for outdoor use. It suits fixing timber to timber and timber to metal in decks, fences and pergolas, and is sold individually.

Brilliant Aussie deal

Been buying Zenith gear for years and this is one of their better ones. The Zenith M8 quality is excellent — everything was included and setup took under 10 minutes. Had it at the door in Brisbane within 2 days. My son immediately claimed it for himself so I had to order another. 10 out of 10.

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.
