S-91760A154 M4 x 16 mm DIN 912, ISO 4762 Alloy Steel Thread-Locking Socket Head Screws

Key Features & Benefits at a Glance

• Vibration-resistant secure fastening with integrated nylon patch thread locker that maintains integrity across a wide temperature range from -70° to 250°F
• Exceptional durability and strength from black-oxide alloy steel construction with Rockwell C37 hardness and 170,000 psi tensile strength for demanding applications
• Precise installation and removal enabled by the 3mm hex drive socket head design, preventing stripping and ensuring reliable torque transmission
• Superior thread engagement with Class 5g6g thread fit and coarse M4 x 0.7mm pitch for quick assembly and reduced cross-threading risk
• Full-length threading versatility allowing consistent clamping force distribution along the entire 16mm length
• Corrosion-resistant protection through black-oxide surface treatment that extends service life in harsh industrial environments
• Global compliance assurance meeting DIN 912/ISO 4762 standards plus RoHS 3 and REACH environmental regulations

Professional Applications & Engineering Value

Engineered for critical assembly applications, these M4 socket head cap screws deliver reliable performance where vibration resistance and precise fastening are paramount. The black-oxide alloy steel construction combined with Rockwell C37 hardness provides exceptional wear resistance in machinery, automotive, and industrial equipment. The integrated nylon patch thread locker eliminates the need for separate locking washers or adhesives, simplifying assembly while preventing loosening under dynamic loads. The fully threaded metric design with coarse 0.7mm pitch ensures rapid installation in production environments, while the 3mm hex drive accommodates standard tools for consistent torque application. These socket head cap screws are particularly valuable in applications requiring repeated disassembly and reassembly, where thread integrity and locking performance must be maintained throughout the product lifecycle.

Specification Summary & Compliance

This metric socket head cap screw features precise M4 x 0.7mm coarse threading with Class 5g6g thread fit tolerance per ISO standards. Manufacturing complies with DIN 912/ISO 4762 specifications for dimensional accuracy and mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring restricted substance adherence. The fully threaded design with right-hand thread direction provides consistent fastening performance across the entire 16mm length.
