Stainless Steel Screws

Powerdrive FDX Fasteners
Powerdrive FDX series are self-drilling and is made of high-strength & wear-resistant AISI SUS 410 grade material, offering reliable and long-lasting corrosion resistance, as well durable fastening for all applications.

The Powerdrive FDX has in the composition Carbon (0.12% ~ 0.15%), and Chromium (11.5% ~ 13.5%). It is tempered Martensitic (hard steel crystalline structure formed though rapid cooling), thus giving good hardness and high toughness to the FDX series.

All technical & performance data along with our selection of stainless steel fasteners can be found below.
