S-97505A134 M6 DIN 923 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc plating, extending service life in harsh industrial environments
• Exceptional mechanical strength from alloy steel construction, supporting up to 58000 psi tensile strength for heavy-duty applications
• Precise alignment and smooth rotation with a 20mm shoulder length and smooth texture, reducing wear on mating components
• Reliable thread engagement with Class 6g fit and coarse 1mm pitch, ensuring quick assembly and vibration resistance
• Low-profile socket head design for space-constrained installations while providing secure slotted drive torque transmission
• Compliance with international standards including DIN 923, RoHS 3, and REACH, guaranteeing safety and regulatory acceptance
• Consistent dimensional accuracy with tight shoulder diameter and length tolerances, enabling repeatable precision in automated assembly

Professional Applications & Engineering Value

This M6 shoulder screw delivers critical engineering value in mechanical assemblies requiring precise shaft positioning and rotational freedom. The alloy steel core, hardened to Rockwell B71, withstands repetitive shear and tensile stresses in automation equipment, conveyor systems, and precision machinery. The zinc-plated finish combats oxidation in humid or outdoor settings, while the low socket head and slotted drive accommodate both hex key and flathead tooling for flexible maintenance. With its 20mm shoulder length and coarse metric thread, it eliminates bushing needs in pivoting joints and linear guides, reducing part count and assembly time. Engineers specify this DIN 923 shoulder screw for its predictable performance in high-cycle applications where component wear and misalignment are primary failure concerns.

Specification Summary & Compliance

Manufactured to DIN 923 specifications with M6x1mm coarse threads and Class 6g thread fit tolerance. Shoulder diameter measures 8 mm with a tolerance of -0.036 mm to 0 mm, and shoulder length is 20 mm with a tolerance of 0.1 mm to 0.2 mm for precise component mating. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries.
