S-96738A125 M8 x 40 mm DIN 912, ISO 4762 Vibration-Resistant Sealing Socket Head Screws

Key Features & Benefits at a Glance

• Permanent vibration resistance with integrated nylon patch thread locker, ensuring secure fastening in high-stress environments without loosening.
• Superior corrosion resistance from 18-8 stainless steel construction, ideal for harsh industrial or outdoor applications with extended service life.
• High tensile strength of 100,000 psi provides reliable load-bearing capacity for critical assemblies, reducing the risk of fastener failure.
• Wide temperature tolerance from -70° to 250°F for the thread locker and -40° to 225°F with optional Buna-N O-ring, ensuring performance in extreme conditions.
• Precise Class 6g thread fit and coarse 1.25mm pitch for quick, accurate installation and reduced cross-threading in metric assemblies.
• Durable Rockwell B85 hardness offers excellent wear resistance, maintaining thread integrity through repeated use and adjustments.
• Seamless compatibility with standard 6mm hex tools and O-ring seals for up to 1500 psi pressure, enabling leak-proof connections in fluid systems.

Professional Applications & Engineering Value

Engineered for demanding industrial fastening scenarios, this M8 socket head cap screw combines 18-8 stainless steel durability with a permanent nylon patch thread locker to solve common issues like vibration-induced loosening in machinery, automotive, and aerospace components. The coarse thread design with 1.25mm pitch accelerates assembly in coarse-grained materials, while the partially threaded rod and Class 6g fit ensure precise alignment and clamping force distribution. With a Rockwell B85 hardness and 100,000 psi tensile strength, it withstands heavy dynamic loads, making it ideal for high-strength cap screw applications where reliability under pressure—up to 1500 psi with optional Buna-N O-rings—is critical for operational safety and reduced maintenance.

Specification Summary & Compliance

This metric socket head screw adheres to DIN 912 / ISO 4762 standards, ensuring dimensional accuracy with a Class 6g thread fit and 40mm length (minimum thread length 28mm). It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material traceability for global industrial use.
