Overview
A cap head SEMS screw with a hex socket and a small plain washer held captive under the head. The washer is fitted before the thread is rolled, so it cannot fall off: the screw and washer go in as one part, which saves time on the line and stops loose washers getting lost in equipment.
Made in 316 stainless steel (A4) (A4-70), passivated or chemi-black. Head dimensions to BS EN ISO 4762 / DIN 912. Sizes M2.5 x 0.45 to M4 x 0.7.
