S-91310A620 M10 x 16 mm ISO 4017, DIN 933 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 150,000 psi tensile strength for reliable performance in demanding applications
• Superior wear resistance due to Rockwell C32 hardness, ensuring extended service life under repetitive stress
• Optimized installation efficiency with external hex drive design providing secure tool engagement and torque transmission
• Enhanced vibration resistance through coarse 1.5 mm pitch threading that maintains secure fastening in dynamic environments
• Full-thread engagement capability allowing maximum grip strength across the entire 16 mm length
• Precision manufacturing compliance with Class 6g thread fit ensuring consistent mating with standard nuts and components
• Environmental regulation adherence meeting RoHS 3 and REACH requirements for safe industrial usage

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these Class 10.9 steel hex head screws deliver critical reliability in machinery assembly, structural frameworks, and equipment manufacturing. The fully threaded metric coarse pitch design prevents loosening under vibration while facilitating rapid installation in time-sensitive production environments. With M10×1.5 mm threading and external hex drive configuration, these fasteners provide superior clamping force distribution in steel-to-steel connections, addressing common failure points in high-stress assemblies. The 16 mm length offers optimal engagement depth for medium-thickness materials, making them ideal for automotive components, industrial machinery, and construction applications where high tensile strength and consistent performance are paramount.

Specification Summary & Compliance

Manufactured to ISO 4017/DIN 933 specifications with Class 6g thread tolerance ensuring precise dimensional accuracy. The metric coarse thread (M10×1.5 mm) follows standardized spacing requirements for compatibility with industry-standard components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and regulatory acceptance for international industrial markets.
