Cup square screws are mainly used in timber construction, as the square under the head pulls into the wood.
The head of cup square screws is a shallow dome with a large diameter – coupled with a square underneath.
Options include A2 stainless steel as well as a zinc-plated option which is more resistant to corrosion.
Made to DIN 603 specification, our cup square screws are available in thread sizes of M5, M6 and M8, with lengths up to 80mm.
