S-97050A199 M20 x 110 mm DIN 6912 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Enhanced Durability & Corrosion Resistance: Black-oxide coating on alloy steel provides superior protection against rust and wear in harsh industrial environments.
• High Tensile Strength for Demanding Applications: Class 8.8 strength rating with 110,000 psi tensile strength ensures reliable performance under heavy loads and vibrations.
• Secure and Efficient Installation: Low profile socket head with 17mm hex drive and 10mm pilot recess offers excellent torque transmission and prevents driver slippage.
• Optimized Fastening with Partial Threading: Partially threaded design (46mm thread length on 110mm overall length) provides precise clamping force and reduces weight.
• Industry-Standard Compliance: Manufactured to DIN 6912 specifications and RoHS 3 compliant, ensuring consistent quality and environmental safety.
• Coarse Thread for Quick Assembly: M20 x 2.5mm coarse thread enables faster installation and reduced cross-threading risks in production lines.
• Accurate Thread Fit for Secure Connections: Class 6g thread tolerance guarantees proper engagement and vibration resistance in mechanical assemblies.

Professional Applications & Engineering Value

This M20 low profile socket head cap screw delivers exceptional engineering value in heavy machinery, automotive, and structural applications where space constraints and high strength are critical. The black-oxide alloy steel construction combats corrosion while maintaining Rockwell C20 hardness, preventing premature failure in demanding environments. Its partially threaded metric design with coarse 2.5mm pitch allows for rapid assembly and reliable clamping in thick materials. The hex with pilot recess drive ensures maximum torque application without stripping, reducing installation errors. By meeting DIN 6912 standards, these screws provide predictable performance in jigs, fixtures, and high-stress assemblies, minimizing downtime and maintenance costs.

Specification Summary & Compliance

This fastener features precise Class 6g thread fit with M20 x 2.5mm coarse metric threads and 46mm minimum thread length. It complies with DIN 6912 manufacturing specifications for dimensional accuracy and mechanical properties. The product is RoHS 3 (2015/863/EU) compliant, ensuring it meets strict environmental regulations for hazardous substance restrictions.
