Key Features & Benefits at a Glance

  • Exceptional corrosion resistance from 18-8 stainless steel construction, ideal for harsh industrial environments.
  • Superior torque transmission and non-slip grip due to the knurled socket head with a 4mm hex drive.
  • High mechanical strength with 70,000 psi tensile and 45,000 psi shear strength for demanding, heavy-duty applications.
  • Precise component location and smooth rotation enabled by the 35mm shoulder with a tightly controlled diameter tolerance.
  • Reliable and coarse-threaded engagement with an M6x1mm Class 5g6g thread for robust fastening.
  • Enhanced durability and minimal light reflection provided by the black oxide surface finish.
  • Guaranteed quality and material safety through compliance with ISO 7379, RoHS 3, and REACH standards.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to solve critical alignment and wear challenges in mechanical assemblies. The precision-ground 35mm shoulder acts as a built-in pivot or bearing surface, eliminating the need for and cost of separate spacers or bushings. Manufactured from 18-8 stainless steel, it provides excellent resistance to rust and corrosion, making it a reliable choice for food processing, packaging, and outdoor equipment. The black oxide finish not only adds a layer of protection but also reduces galling. Combined with the knurled socket head for high-torque installation, this ISO 7379 certified fastener ensures long-lasting performance and simplified maintenance in high-stress applications.

Specification Summary & Compliance

This precision shoulder screw features an M6x1mm coarse thread with a Class 5g6g tolerance for a reliable fit. The shoulder diameter is held to a tight tolerance of -0.072 to -0.01 mm, and the shoulder length tolerance is 0 to 0.25 mm. It is manufactured in accordance with the ISO 7379 standard and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances.
