S-98451A137 M6 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 360 brass material, ideal for harsh industrial environments and reducing maintenance costs.
• Precise alignment and stability due to the 8mm shoulder diameter with tight tolerance (-0.025 to 0 mm), ensuring accurate component positioning.
• High durability and strength from Rockwell B55 hardness and 40,000 psi tensile strength, providing reliable performance under load.
• Easy installation and removal with a 4mm hex drive socket head, allowing for quick assembly with standard tools.
• Consistent thread engagement with Class 6g thread fit and M6x1mm coarse pitch, minimizing cross-threading risks in high-speed applications.
• Environmental compliance assurance by meeting RoHS 3 and REACH standards, supporting sustainable and safe manufacturing practices.
• Smooth head texture for reduced friction and damage to mating surfaces, enhancing overall assembly integrity.

Professional Applications & Engineering Value

This M6x1mm shoulder screw is expertly crafted from 360 brass to address critical alignment challenges in industries like machinery, electronics, and automotive assemblies. The precise shoulder diameter and length tolerances ensure minimal play, preventing misalignment and wear in rotating parts or pivot points. With a socket head hex drive, it facilitates secure tightening in confined spaces, while the Class 6g thread and coarse pitch enable rapid installation without sacrificing hold strength. The brass construction offers inherent corrosion resistance, making it suitable for moist or chemical-exposed environments, and its compliance with RoHS and REACH supports eco-friendly production. Engineers value this screw for maintaining dimensional stability in precision fastening applications, reducing downtime and improving operational efficiency.
