Cup Square Screws are mainly used in timber construction, as the square under the head of the screw pulls into wood to create a secure fastening.
The head of Cup Square Screws is a shallow dome with a larger diameter, coupled with a square underneath.
Available as standard as A2 stainless steel as well as a zinc-plated option which is more resistant to corrosion.
These Cup Square Screws are made to DIN standard 603 and are available in thread sizes of M5, M6 and M8, with lengths of up to 80mm.
