Description

• Hexagon Flange Head Bolts DIN6921

 

• Material: Carbon Steel, Stainless Steel

 

• Finish: Self Colour | Black Oxide | Zinc Plated | HDG | Zinc Flake

 

•The flange head helps spread the load over a greater area

 

• Original self-tapping anchor with the power to be used on a whole range of construction materials including concrete, brick and stone

 

It is a one-piece, non-expansion anchor, meaning that it does not require a wall plug or resin, and therefore makes it ideal for close to edge fixing applications

 

The threaded anchor and self-tapping action allow for safe anchorage, with the substrate becoming the nut to the bolt.
