S-90854A321 M16 x 95 mm ISO 4014, DIN 931 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capability with Class 10.9 strength grade and 150,000 psi tensile strength for reliable performance in high-stress applications
• Superior corrosion resistance provided by zinc yellow-chromate plating, extending service life in harsh industrial environments
• Optimized thread engagement through M16 x 2mm coarse pitch design ensuring faster assembly and reduced cross-threading risks
• Enhanced torque transmission via external hex drive and 24mm head width for secure installation with standard tools
• Precision thread fit with Class 6h tolerance ensuring consistent performance and vibration resistance
• Strategic partial threading allowing unthreaded shank section for improved shear strength in structural connections
• Rockwell C32 hardness providing excellent wear resistance and durability through repeated use cycles

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these Class 10.9 hex head screws deliver critical performance where failure is not an option. The zinc yellow-chromate plated steel construction provides superior corrosion protection in manufacturing facilities, outdoor equipment, and machinery exposed to harsh conditions. The M16 coarse thread pitch enables rapid installation in structural steel connections, heavy machinery assembly, and construction applications where time efficiency matters. The partially threaded design concentrates threads where needed while maintaining full shank diameter for enhanced shear strength in bolted joints. With 95mm length and 38mm minimum thread length, these metric hex bolts accommodate various material thicknesses while ensuring sufficient thread engagement for secure fastening in critical load-bearing applications.

Specification Summary & Compliance
