S-96144A120 M6 x 20 mm DIN 912, ISO 21269 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional strength and durability with Class 12.9 rating and 170,000 PSI tensile strength for reliable performance in high-stress applications.
• Superior corrosion resistance provided by the black-oxide coating on alloy steel, extending service life in demanding industrial environments.
• Precise torque application enabled by the 5mm hex socket drive, ensuring secure fastening and reducing the risk of tool slippage.
• Fine thread design (0.75mm pitch) offers improved vibration resistance and better clamping force distribution compared to coarse threads.
• Full thread coverage along the 20mm length allows for maximum adjustability and consistent holding power throughout the engagement.
• High hardness (Rockwell C37) maintains thread integrity and prevents deformation under heavy loads.
• Global standard compliance with DIN 912/ISO 21269 ensures interchangeability and reliability in international engineering projects.

Professional Applications & Engineering Value
