  • Head type: Hex
  • Finish: Yellow zinc
  • Grade: Hi-tensile
  • Pack quantity: 4 bolts with matching nuts

Brilliant Aussie deal

Been buying Pinnacle gear for years and this is one of their better ones. The Pinnacle M12 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.
