S-96738A098 M3 x 50 mm DIN 912, ISO 4762 Vibration-Resistant Sealing Socket Head Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking with nylon patch thread locker maintains secure fastening in dynamic environments from -70° to 250°F
• Reliable fluid and dust sealing through integrated Buna-N rubber O-ring that performs across -40° to 225°F temperature range
• Exceptional mechanical strength with 100,000 psi tensile strength and Rockwell B85 hardness for heavy-duty applications
• Superior corrosion resistance provided by 18-8 stainless steel construction in harsh industrial environments
• Precise dimensional compliance with DIN 912/ISO 4762 standards ensures perfect fit and interchangeability
• Easy installation and removal via standard hex socket drive requiring only 2.5 mm hex key
• Optimized pressure handling capable of withstanding up to 1500 psi in sealed applications

Professional Applications & Engineering Value

These M3 socket head cap screws deliver critical performance where vibration resistance and environmental sealing are paramount. The combination of nylon patch thread locking and Buna-N O-ring sealing addresses two major industrial challenges: fastener loosening under dynamic loads and contamination ingress. Manufactured from 18-8 stainless steel, these metric screws provide excellent corrosion resistance while maintaining high tensile strength for demanding applications in machinery, automotive assemblies, and electronic enclosures. The partially threaded design with Class 6g thread fit ensures precise engagement while the standardized hex drive configuration allows for efficient installation in confined spaces. These engineered fasteners prevent costly downtime by eliminating the need for secondary locking devices and separate seals.

Specification Summary & Compliance

This socket head cap screw features M3 x 0.5 mm coarse threads with Class 6g tolerance, 18 mm minimum thread length, and 50 mm overall length. Manufactured to DIN 912 ISO 4762 specifications for dimensional accuracy and performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
