Description & Specs

The Hobson M12 x 30mm Purlin Zinc Plated Bolts are a 10 pack of mild steel fasteners with a hex flange head for secure structural fixing.

  • Bolt size: M12 x 30mm
  • Material: Mild Steel
  • Head type: Hex Flange
  • Finish: Zinc Plated
  • Pack quantity: 10
  • Includes: Bolts and nuts

The hex flange head spreads load across a wider bearing surface, so the bolt clamps firmly without needing a separate washer. The zinc plated finish adds corrosion resistance for internal applications, and each bolt comes with a matching nut. Supplied as a 10 pack and packed in a resealable trade bag, these purlin bolts suit steel framing, purlins and general structural fastening work.

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 Hobson M12 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.
