S-93401A207 6-32 x 5/8" ASTM F835, MS24667-10 Alloy Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 140,000 psi ensures reliable fastening under high-stress conditions, reducing the risk of failure in demanding applications.
• Superior corrosion resistance provided by cadmium plating extends service life and maintains performance in harsh industrial environments.
• Precise Class 3A thread fit guarantees tight, secure connections with minimal play, enhancing assembly accuracy and vibration resistance.
• Full threading along the 5/8" length maximizes grip and load distribution, offering consistent holding power across the entire fastener.
• 82° countersink angle with standard flat head profile allows for flush mounting, improving aesthetics and reducing snag hazards in assembled products.
• High hardness (Rockwell C39) increases wear resistance, ensuring the screw maintains its integrity through repeated use and installation.
• Hex drive (5/64") design enables easy installation with standard tools, speeding up assembly processes and reducing labor time.

Professional Applications & Engineering Value

Engineered for industrial and mechanical assemblies, this 6-32 UNC flat head screw in cadmium-plated alloy steel addresses critical needs for durability and precision.
