RS PRO Key Steel Square Bar, 330 x 12 x 12 mm


Looking for a durable material for construction or engineering purposes? Choose this steel square bar from RS PRO. It's made of a key steel material, so it's strong enough to withstand heavy-duty tasks. The material has a zinc and chromate finish, which gives it enhanced resistance to corrosion and makes it suitable for use both indoors and outdoors.


The length of the bar is 330 mm, which is sufficient for a small-scale project. If you need a shorter length, the steel material is easily cut. Its thermal resistance also makes it suitable for use in machines that generate a lot of heat. This square bar is commonly used in the manufacture of gib heads for diesel generators and different kinds of keys for construction machinery.
