Countersunk screw according to ISO 10642 / DIN 7991 in steel grade 8.8 with zinc-plated (ZN) surface and STAR drive. The STAR drive provides improved torque transfer and reduces the risk of cam-out compared to hex socket versions. Suitable for applications requiring even tightening and a flush fit, such as machinery, steel structures, and equipment assemblies. Zinc coating provides basic corrosion protection for indoor or dry environments. Available in multiple sizes from SWEBOLT & BOTNIA BOLT.
