hardened concrete steel nails

“HJZ” hardened concrete steel nails are made of specially hardened steel with a hardness of 52-54 HRc and a bending angle of 45-90 degrees. The nails receive a special rust treatment and are available with a smooth or a grooved (ribbed) shaft. The steel nails can be manufactured in a blue/black execution, but can also be galvanized, like electro galvanizing and mechanical galvanizing. The steel nails provide strength and durability. Important is to choose the correct nail for each specific application. “HJZ” steel nails are used for various purposes, like the construction industry / upholstery / carpentry / wood working / craft projects. The steel nails are also available as a ribbed (grooved) nail (both electro galvanized and mechanical galvanized). Apart from the smooth and grooved (ribbed) hardened concrete steel nails, the range also contains harsteel nails like the Z1 clamp nail, Z2 lath nail, Z3 skirting board nail, the Fixpin and the M6 pin (Dübel).
