Grade Class 8.8 10.9 12.9 Black Oxide Zinc Nickel Plating Cross Recessed Round Head Metal Screw Assembled With Washer
Product Description
This series of SEMS screws uses high‑strength carbon steel with property classes 8.8, 10.9 and 12.9 to cover medium to extreme load conditions. The cross recessed round (pan) head accepts standard Phillips drivers. Surface finishes include black oxide (with oil film), blue/white/yellow zinc plating, and nickel plating – each offering different levels of corrosion protection and appearance. A flat or combination washer is pre‑assembled to distribute load and protect the workpiece surface. These screws are designed for general mechanical, automotive and industrial applications where strength and cost‑effectiveness are key.
