ART 8220 A4 Half lock straight

ART 8220 Straight half-lock is a fastening element used to connect two parts of metal structures, usually doors or windows. Semi-lock provides a strong connection, and also allows easy opening and closing of doors or windows.

The use is used in marine and river transport infrastructure, as well as on ships, where it is important to ensure a strong and reliable connection of doors and windows, as well as to ensure their easy opening and closing.

The material is stainless steel. The A4 steel grade allows the use of fasteners at significant temperature changes and in an aggressive and humid environment.
