S-91290A846 M16 x 120 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 psi ensures reliable performance in the most demanding applications, reducing the risk of fastener failure.
• Superior corrosion resistance provided by the black-oxide coating extends service life and maintains integrity in harsh industrial environments.
• High hardness rating of Rockwell C37 offers excellent wear resistance, maintaining thread integrity and drive engagement over repeated use.
• Precise Class 5g6g thread fit ensures smooth assembly and secure fastening, minimizing play and vibration loosening in machinery.
• Standard hex drive design with 14mm drive size allows for easy installation and high torque application using common tools.
• Partially threaded shank provides optimal grip length for joint clamping while allowing unthreaded sections to bear shear loads effectively.
• Full compliance with international standards including DIN 912/ISO 4762 guarantees dimensional accuracy and interchangeability in global applications.

Professional Applications & Engineering Value

This M16 socket head cap screw delivers critical engineering value in heavy-duty applications where failure is not an option. The Class 12.9 alloy steel construction provides exceptional load-bearing capacity for machinery, automotive assemblies, and industrial equipment subjected to high stress and vibration. The coarse 2mm pitch metric threads enable rapid assembly while maintaining secure fastening, significantly reducing installation time in production environments. The black-oxide surface treatment creates a protective barrier against oxidation and chemical exposure, making these socket head screws ideal for outdoor equipment, manufacturing plants, and automotive applications where corrosion resistance is essential. The combination of 170,000 psi tensile strength and precise DIN 912/ISO 4762 manufacturing standards ensures consistent performance and reliability across critical joints and structural connections.
