Product Description

These precision SEMS screws feature a cross recessed pan head with a polished, mirror‑like finish that enhances appearance.

Manufactured from A2 (304) or A4 (316) stainless steel with strength classes 70 or 80, they are ideal for compact electronic and instrument assemblies. The pan head provides a larger bearing surface, while the polished surface offers a bright, uncoated look. Conforming to DIN7985 (screw), DIN125 (flat washer) and DIN127 (spring washer), these screws ensure dimensional consistency and interchangeability.
