More about this product

KKZ A2 screws from Rothoblaas are countersunk cylindrical head screws with a double thread and special tip for use on hardwoods.

Double Thread

The larger diameter right-hand under-head thread ensures an effective grip, guaranteeing good coupling of the wooden elements. Concealed head.

Burnished version

Rothoblaas supplies a version in antique-burnished stainless steel, ideal to guarantee superb camouflaging in the wood.

Fields of Use

Hard Wood

The special tip with sword-shaped geometry specially designed to efficiently drill very high-density woods without pre-drill (with pre-drill, over 1000 kg/m3). Tested on very high-density woods, such as IPE, massaranduba or bamboo Microllam® (over 1000 kg/m3).
