A2-70 Stainless Hex Flange Screw – Serrated Undercut

Product Overview

Our A2-70 Stainless Hex Flange Screw combines the corrosion resistance of 304 stainless steel with a serrated undercut design to deliver unmatched vibration-proof performance in demanding environments. Ideal for automotive, marine, and industrial machinery, this screw features an integrated flange to eliminate the need for washers and serrated threads that bite into materials, preventing loosening under dynamic loads.

Key Features

✅ A2-70 Stainless Steel (304 Grade)

Corrosion Resistance: Withstands saltwater, humidity, and mild chemicals, perfect for marine and outdoor applications.
High Tensile Strength: 700 MPa tensile strength for secure, long-lasting fastening.

✅ Hex Flange Head

Integrated Washer Function: Distributes load evenly, reducing surface damage on soft materials like plastics or composites.
Hex Drive Compatibility: Compatible with standard wrenches or sockets (e.g., 10mm for M6).

✅ Serrated Undercut Design

Anti-Vibration Performance: Serrations under the flange bite into the material, resisting rotation and loosening.
Reusable: Maintains grip even after multiple installations.

✅ Certified Quality

ISO 3506 (Stainless Steel Fasteners), ASTM F593, RoHS, and ISO 9001 compliant.
