• Enhanced durability and wear resistance provided by the black oxide finish, which also reduces light reflection
li>Precise component alignment and smooth rotation enabled by the 20mm shoulder diameter with tight tolerance control
• High-strength fastening with 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable load-bearing applications
• Secure, non-slip installation using the 10mm hex socket drive and knurled head for improved grip during torque application
• Wide compatibility and easy assembly with standard M16x2mm coarse right-hand threads and Class 5g6g fit for consistent engagement
• Global regulatory compliance meeting ISO 7379, RoHS 3, and REACH standards for safe use in various markets

Professional Applications & Engineering Value

This M16 shoulder screw is engineered to solve critical alignment and pivot point challenges in precision assemblies. The 316 stainless steel material provides exceptional resistance to chemicals, saltwater, and industrial atmospheres, preventing premature failure in demanding applications like machinery, automotive fixtures, and conveyor systems. The black oxide finish not only enhances corrosion protection but also minimizes galling and seizing during repeated adjustments. The knurled head and hex socket drive allow for secure tool engagement in tight spaces, reducing installation time and improving worker safety. With its 20mm shoulder diameter and controlled shoulder length, this screw ensures precise locating of components, eliminating misalignment and reducing wear on moving parts, making it an ideal choice for rotational mechanisms and jig and fixture construction.

Specification Summary & Compliance

This shoulder screw features M16x2mm coarse metric threads with a Class 5g6g thread fit for standard engagement. The shoulder diameter tolerance is controlled between -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm, ensuring high dimensional accuracy. It is manufactured in compliance with ISO 7379 and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial use.
