S-97505A129 M6 DIN 923 Shoulder Screws

Key Features & Benefits at a Glance

• High-strength alloy steel construction provides excellent durability and a tensile strength of 58,000 psi for reliable performance in demanding applications.
• Zinc plating finish offers superior corrosion resistance, extending the screw's service life in various industrial environments.
• Precision Class 6g thread fit ensures smooth and secure assembly, reducing the risk of cross-threading and improving installation efficiency.
• Low-profile socket head design allows for a compact installation in space-constrained applications while providing a secure drive with a slotted option.
• 8mm shoulder diameter with standard fit acts as a precise pivot, bearing surface, or locator, enhancing component alignment and reducing wear.
• Rockwell B71 hardness rating guarantees high resistance to deformation under load, maintaining dimensional stability.
• Compliance with DIN 923, RoHS 3, and REACH ensures adherence to international quality and environmental safety standards for global sourcing.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and pivot requirements in machinery and assemblies. The alloy steel core, hardened to Rockwell B71, provides the necessary strength to withstand rotational forces and shock loads without failing. The 8mm shoulder diameter and 6mm shoulder length offer a precise locating feature, eliminating the need for additional bushings or spacers, which simplifies design and reduces parts count. The zinc plated finish combats corrosion in humid or outdoor settings, while the low-profile socket head is ideal for applications where clearance is limited. With a coarse M6x1mm thread and Class 6g fit, it ensures quick and reliable fastening in industrial applications such as robotics, conveyor systems, and precision instruments, reducing assembly time and improving overall equipment reliability.

Specification Summary & Compliance
