Overview

A hexagon head with cross recess (phillips) SEMS screw with a plain washer and spring washer held captive under the head. The spring washer sits against the head and the plain washer outside it; both are fitted before the thread is rolled, so they cannot fall off. The screw and washers go in as one part, which saves assembly time and stops loose washers getting lost in equipment.

Made in stainless steel SS 304 (A2). Same can be manufactured in SS 316 (A4) against orders. Sizes M3 to M10.
