S-91290A749 M14 x 70 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 under extreme loads, reducing the risk of fastener failure in demanding applications.
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life and maintaining integrity in harsh industrial environments.
• Precise hex drive engagement with a 12 mm drive size and standard socket head profile, allowing for secure tool fitting and minimizing stripping during installation.
• Optimized thread design with coarse M14x2mm right-hand threads and Class 5g6g fit, providing quick assembly and consistent clamping force in various materials.
• High hardness rating of Rockwell C37 enhances wear resistance, ensuring the screw maintains its structural integrity through repeated use and vibration.
• Versatile partial threading with a 40 mm minimum thread length, offering flexibility for applications requiring both threaded and unthreaded sections.
• Compliance with international standards including DIN 912/ISO 4762, ensuring dimensional accuracy and interchangeability for global engineering projects.

Professional Applications & Engineering Value

This M14 socket head cap screw is engineered to address critical challenges in heavy-duty industrial settings, such as machinery assembly, automotive systems, and construction equipment. The Class 12.9 alloy steel construction, combined with a black-oxide surface treatment, provides superior resistance to corrosion and wear, reducing maintenance downtime. The coarse metric thread (M14x2mm) and right-hand thread direction facilitate rapid installation in high-vibration environments, while the 12 mm hex drive ensures secure torque application without slippage. Ideal for applications requiring high tensile strength and durability, these screws deliver reliable performance in demanding conditions, from manufacturing fixtures to structural frameworks.
