Purlin Bolt and Nut

The bolt and nut for fixing purlins, sold as a set.

These zinc plated purlin bolts come with a matching flange nut. The flange under the bolt head and on the nut spreads the load over a wider area than a plain hex bolt and saves fitting separate washers. Use them to bolt C and Z purlins to cleats, brackets and each other at laps. Also searched as purlin bolts, flange bolts or cleat bolts.

Pick the size that suits your job:

• M12 x 30mm – the go-to size for most purlin and bracket connections
• M16 x 35mm – for heavier connections that call for an M16 bolt

Features:

• Flange head bolt with a matching flange nut, sold together each
• Property class 4.6
• Zinc plated
• Sizes: M12 x 30mm and M16 x 35mm

Common applications:

• Fixing C and Z purlins to cleats and brackets
• Lapping and joining purlins
• Sheds, carports, patios and light steel framing

Tip: Pair them with our General Purpose Brackets and C-Purlin.
