S-96144A344 M20 x 60 mm DIN 912, ISO 21269 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength with Class 12.9 rating and 170,000 psi capability, ensuring reliable performance in high-stress industrial applications.
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in harsh environments.
• Precise thread engagement with M20 x 1.5mm extra fine thread and Class 5g6g fit, providing secure, vibration-resistant fastening.
• High durability and wear resistance due to Rockwell C37 hardness, maintaining integrity under repeated loads.
• Easy installation and removal with a 17 mm hex drive and standard socket head, reducing assembly time and tool wear.
• Versatile partial threading for controlled clamping force and reduced risk of cross-threading in precision assemblies.
• Compliance with international standards including DIN 912 and ISO 21269, ensuring consistent quality and interchangeability.

Professional Applications & Engineering Value

This M20 socket head cap screw is engineered to address critical challenges in heavy-duty mechanical systems, where vibration, high loads, and environmental factors can compromise fastener integrity. The black-oxide alloy steel construction offers enhanced corrosion resistance, ideal for machinery exposed to moisture or chemicals. With an extra fine thread (1.5mm pitch) and Class 5g6g thread fit, it ensures tight tolerances and superior grip in fine-adjustment applications, such as precision equipment, automotive assemblies, and industrial robotics. The partially threaded design allows for optimal stress distribution, minimizing the risk of thread stripping and improving clamp load accuracy. By combining high tensile strength (170,000 psi) and Rockwell C37 hardness, this screw delivers long-term reliability, reducing maintenance needs and downtime in demanding operations.

Specification Summary & Compliance
