The Zenith M8 x 20mm hot dipped galvanised hex head bolt and nut is a 4.6 grade steel fastener for construction and repair tasks. The hex head drives with a spanner or socket for strong clamping pressure, and it suits joining metal to metal and metal to timber against the supplied nut.

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.
