S-91280A748 M16 x 200 mm ISO 4014, DIN 931, SAE J1199, ISO 898 Medium-Strength Metric Class 8.8 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Superior tensile strength with Class 8.8 rating (110,000 PSI) ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in demanding applications.
• Enhanced corrosion resistance from zinc plating prolongs service life and maintains integrity in harsh or outdoor environments, minimizing maintenance needs.
• Robust material hardness (Rockwell C21) provides excellent wear resistance and durability, supporting repeated use without deformation.
• Precision partial threading (minimum 38 mm thread length) with M16 coarse pitch (2 mm) allows for secure, rapid installation and optimal grip in thick materials.
• External hex drive design enables easy torque application with standard tools, speeding up assembly and disassembly in industrial settings.
• Compliance with international standards like ISO 4014 and DIN 931 guarantees consistent quality, interchangeability, and safety across global projects.
• Right-hand thread with Class 6h fit ensures tight, vibration-resistant connections, enhancing stability in machinery and structural assemblies.

Professional Applications & Engineering Value

This M16 hex head screw is engineered to address critical fastening challenges in heavy-duty industrial applications, such as construction machinery, automotive frames, and structural steelwork. Made from high-strength steel with a Class 8.8 rating, it withstands extreme loads and vibrations, preventing loosening and failures that can lead to downtime. The zinc-plated finish combats corrosion in humid or chemical-exposed environments, extending component lifespan. With a coarse metric thread (2 mm pitch) and partial threading, it offers quick installation and firm holding power in thick materials, reducing assembly time while ensuring reliable, long-term performance in high-tensile strength scenarios.
