S-91290A884 M30 x 100 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength with Class 12.9 rating (170,000 psi) ensures reliable performance under extreme loads, reducing the risk of fastener failure in critical applications.
• Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life and maintaining integrity in harsh or outdoor environments.
• Precise thread engagement with Class 5g6g fit and coarse 3.5 mm pitch, enabling faster assembly and reduced cross-threading in high-vibration settings.
• High hardness (Rockwell C37) provides excellent wear resistance, minimizing deformation and maintaining clamp force over repeated use.
• Standard hex socket drive (22 mm) allows for easy installation with common tools, offering secure torque application and space-saving in confined areas.
• Full threading along the 100 mm length ensures uniform stress distribution and flexibility in adjustment for various material thicknesses.
• Compliance with DIN 912/ISO 4762 standards guarantees dimensional accuracy and interchangeability, streamlining procurement and inventory management.
