Product Description
This SEMS screw has a hex head with an additional cross recess (dual drive) and comes with a DIN9021 large diameter flat washer pre‑assembled. The large washer provides a much bigger bearing surface than standard washers, making it perfect for soft materials or thin sheet metal with oversized holes. The screw is made of A2 (304) or A4 (316) stainless steel, strength classes 70 or 80. “All sizes" means diameters from M3 up to M12 can be supplied. The dual drive (hex + cross) allows installation with a wrench or a screwdriver – a useful feature for maintenance.
