S-91273A449 M10 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and extended service life.
• Precise alignment and pivot points ensured by the 25mm shoulder with tight diameter tolerance (-0.04 to -0.01 mm) for reliable assembly performance.
• High mechanical strength offering 70,000 psi tensile and 35,000 psi minimum shear strength for demanding applications.
• Enhanced grip and tool engagement from the knurled hex socket head, preventing slippage during installation and removal.
• Wide compatibility and easy installation with standard M10x1.5 coarse right-hand threads conforming to Class 5g6g fit.
• Consistent durability backed by Rockwell B55 hardness, maintaining structural integrity under repeated loads.
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe, environmentally conscious use.

Professional Applications & Engineering Value

This M10x1.5 metric shoulder screw is engineered to address critical alignment and load-bearing challenges in industrial and mechanical assemblies. The 25mm shoulder length with controlled tolerances provides a stable, unthreaded bearing surface, reducing wear on mating components and ensuring precise rotational or linear movement in machinery, pivots, and guides. Manufactured from 18-8 stainless steel, it resists corrosion in moist or chemical-exposed settings, while the hex socket knurled head design enhances torque transmission and prevents cam-out. With a coarse thread and Class 5g6g thread fit, it facilitates quick installation and secure fastening in high-vibration environments, making it a reliable choice for automation equipment, automotive jigs, and precision instruments.

Specification Summary & Compliance

The screw features a 16mm thread length and 25mm shoulder length with diameter tolerance of -0.04 to -0.01 mm and length tolerance of 0 to 0.25 mm. Threads conform to Metric standards with Class 5g6g fit and right-hand orientation. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions adherence.
