S-91290A103 M2.5 x 10 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 high-stress and heavy-duty applications, minimizing the risk of fastener failure.
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in demanding or mildly corrosive environments.
• Maximum durability and wear resistance due to a hardness of Rockwell C37, maintaining thread integrity and head drive through repeated use.
• Precise hex socket drive (2mm) allows for high torque application and secure installation in confined spaces, reducing tool slippage and assembly errors.
• Coarse thread (0.45mm pitch) design enables faster installation and better performance in materials where fine threads may be prone to stripping.
• Full threading along the 10mm length provides consistent clamping force and versatility in adjustment for various material thicknesses.
• Compliance with international standards including DIN 912/ISO 4762, ensuring dimensional accuracy, interchangeability, and quality assurance for global engineering projects.
