Professional Applications & Engineering Value

This precision shoulder screw addresses critical alignment challenges in mechanical assemblies where rotational freedom and axial positioning are paramount. The 316 stainless steel construction with passivated finish provides exceptional resistance to chemicals, moisture, and industrial atmospheres, making it ideal for food processing equipment, marine applications, and chemical processing machinery. The 25mm shoulder length with precise diameter control serves as an accurate pivot point or spacer in rotating mechanisms, eliminating the need for additional bushings or spacers. The hex socket head design allows for compact installation in confined spaces while the M6x1mm thread with Class 6g fit ensures reliable fastening in high-vibration environments. This combination of features makes it particularly valuable in precision instruments, automation equipment, and machinery requiring repeated disassembly and reassembly.

Specification Summary & Compliance
