S-90833A121 M6 Shoulder Screws

Key Features & Benefits at a Glance

• Enhanced Durability & Corrosion Resistance: Black oxide finish provides reliable protection against rust and wear in harsh industrial environments, extending service life.
• Precision Alignment & Reduced Wear: The 8mm shoulder diameter with tight tolerance ensures accurate component positioning, minimizing vibration and part wear.
• High Tensile Strength for Demanding Applications: Alloy steel construction and 140,000 psi tensile strength guarantee secure fastening under high-stress conditions.
• Secure, Low-Profile Installation: Knurled, low-profile socket head with 4mm hex drive allows for compact assembly and superior torque transmission without protrusion.
• Reliable Thread Engagement: M6x1mm coarse pitch thread with Class 5g6g fit ensures easy installation and consistent, vibration-resistant connections.
• Consistent Hardness for Repeated Use: Rockwell C30 hardness maintains structural integrity and thread form through multiple installations and removals.
• Compliance with Global Standards: Meets RoHS 3 and REACH regulations, ensuring safety and environmental responsibility for international supply chains.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and space constraints in precision assemblies. The alloy steel core, combined with a black oxide finish, resists corrosion and mechanical stress, making it ideal for machinery, automotive, and electronics where low-profile socket head design is essential. The 8mm shoulder diameter provides a precise bearing surface, reducing misalignment and wear on moving parts. With a coarse metric thread (M6x1mm) and Class 5g6g fit, it ensures quick, secure fastening in high-vibration environments, enhancing reliability in industrial applications like robotics, conveyor systems, and fixture jigs.

Specification Summary & Compliance

This shoulder screw features an M6x1mm coarse metric thread with Class 5g6g tolerance for precise fit. The shoulder diameter (8mm) and length (10mm) adhere to standard industrial dimensions, with tolerances of -0.072 to -0.01 mm and 0 to 0.25 mm, respectively. Manufactured from alloy steel with Rockwell C30 hardness and 140,000 psi tensile strength, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met.
