S-96755A440 M8 x 30 mm ISO 4017, DIN 933 Medium-Strength Metric Class 8.8 Steel Thread-Locking Hex Head Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking with permanent nylon patch ensures reliable fastening in high-stress environments
• Superior corrosion protection through zinc plating extends service life in demanding industrial conditions
• High tensile strength rating of 110,000 psi provides exceptional load-bearing capacity for critical applications
• Wide temperature tolerance (-55° to 250°F) maintains performance stability across diverse operating environments
• Precision metric threading with Class 6h fit guarantees consistent engagement and optimal clamping force
• External hex drive design enables efficient installation with standard tools while resisting stripping
• Full threading coverage along the 30mm length allows for adjustable positioning and maximum grip range

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M8 hex head screws combine Class 8.8 strength rating with permanent nylon patch thread locking to solve critical vibration-induced loosening problems in machinery, automotive assemblies, and structural frameworks. The zinc-plated steel construction provides essential corrosion resistance while maintaining Rockwell C22 hardness for durability against wear. With coarse metric threading (1.25mm pitch) and full-length threads, these fasteners deliver rapid installation and consistent clamping force across the entire engagement surface, making them ideal for production lines where reliability and efficiency are paramount. The external hex drive ensures compatibility with standard tools while resisting cam-out during high-torque applications.

Specification Summary & Compliance

These metric hex head screws feature precision Class 6h thread fit according to ISO 4017/DIN 933 manufacturing standards, ensuring dimensional accuracy and interchangeability. The fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for global industrial applications. Manufacturing specifications include right-hand coarse threading with M8 x 1.25mm parameters and 30mm fully threaded length, providing reliable performance meeting international quality standards for industrial fastening systems.
