S-91263A852 M10 x 50 mm DIN 7991, ISO 10642 Alloy Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 120,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Superior corrosion resistance from zinc plating extends service life in harsh industrial environments, minimizing maintenance and replacement costs.
• High hardness rating (Rockwell C32) provides excellent wear resistance and durability under repetitive loads and vibrations.
• Precise Class 6g thread fit guarantees smooth installation and secure fastening, compatible with standard metric nuts and tapped holes.
• 6mm hex drive design allows for high-torque application with common tools, speeding up assembly and reducing labor time.
• Partially threaded shank offers optimal grip and clamping force where needed, preventing joint loosening in dynamic applications.
• Compliance with DIN 7991/ISO 10642 standards ensures dimensional accuracy and interchangeability, facilitating global sourcing and quality assurance.

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M10 flat head screws with Class 10.9 strength and zinc-plated alloy steel construction address critical challenges in machinery, automotive, and structural assemblies. The coarse thread (1.5 mm pitch) and partial threading enhance grip in soft materials and reduce the risk of cross-threading, while the flat head profile sits flush for streamlined surfaces. With a Rockwell C32 hardness and 120,000 psi tensile strength, they withstand heavy vibrations and dynamic loads, preventing fatigue failures. The hex drive ensures efficient installation in confined spaces, making them ideal for maintenance and production lines where reliability and speed are paramount.
