S-97050A243 M8 x 40 mm DIN 6912 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc plating, extending service life in harsh industrial environments.
• High tensile strength of 110,000 psi (Class 8.8) ensures reliable, fail-safe fastening under heavy loads.
• Low-profile socket head design allows for installation in tight spaces with a standard 6mm hex key.
• Precise Class 6g thread fit guarantees smooth assembly and consistent clamping force.
• Partially threaded shank provides unthreaded bearing surface for improved shear strength and alignment.
• Compliance with DIN 6912 standard ensures dimensional accuracy and interchangeability.
• RoHS 3 compliance meets environmental regulations for safe use in various industries.

Professional Applications & Engineering Value

Engineered for demanding industrial applications, this M8 socket head cap screw combines a zinc-plated alloy steel construction with a coarse 1.25mm pitch metric thread to resist loosening under vibration. The low-profile hex drive with pilot recess enables high torque application without cam-out, making it ideal for machinery, automotive assemblies, and structural frames where space is constrained and reliable fastening is critical. Its partially threaded design concentrates stress away from the thread root, enhancing fatigue resistance and durability in dynamic load conditions.

Specification Summary & Compliance

This fastener features an M8 x 1.25mm coarse thread with a Class 6g tolerance for precise fit, a minimum thread length of 22mm, and a total length of 40mm. Manufactured to meet DIN 6912 specifications for dimensional consistency and is RoHS 3 (2015/863/EU) compliant, ensuring adherence to international safety and environmental standards for industrial components.
