S-90187A122 M16 x 3 11/16" ISO 4017, DIN 933 Tight-Spot Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with Class 8.8 strength grade, supporting tensile loads up to 110,000 PSI and shear resistance of 69,600 PSI for reliable performance in demanding applications.
• Superior corrosion resistance provided by the zinc-plated steel construction, extending service life in harsh industrial environments.
• Secure vibration-resistant locking through the expanding sleeve mechanism, preventing loosening under dynamic loads and enhancing assembly integrity.
• Optimized installation efficiency with external hex drive and 24mm head width, allowing for quick tightening using standard tools.
• Precision thread engagement with M16x2mm coarse metric threads and Class 6g fit, ensuring consistent clamping force and reducing cross-threading risks.
• Full-threaded design for maximum grip length across material thicknesses from 1 1/8" to 2", providing versatile fastening solutions.
• Regulatory compliance assurance meeting DIN 933, ISO 4017, RoHS 3, and REACH standards for global quality and environmental safety.

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these M16 hex head screws deliver critical performance where structural integrity is paramount. The zinc-plated steel construction provides essential corrosion protection for machinery, structural steel connections, and outdoor equipment. With Class 8.8 tensile strength (110,000 PSI) and Rockwell C22 hardness, they withstand extreme mechanical stresses in construction, manufacturing, and automotive assemblies. The expanding sleeve locking mechanism effectively counters vibration-induced loosening, a common failure point in dynamic systems. The fully threaded metric design with 2mm coarse pitch ensures rapid installation and reliable clamping across varying material thicknesses, while the external hex drive accommodates standard wrenches for efficient maintenance access.

Specification Summary & Compliance
