Overview

A pan head SEMS screw with a cross recess (type Z) and a 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), passivated or chemi-black. Head dimensions to DIN 7985 type Z recess. Sizes M3 x 0.5 to M6 x 1.0.
