S-93856A151 M2 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Precise component alignment thanks to the knurled head texture that prevents slipping during installation
• High-strength performance with 70,000 psi tensile strength and 35,000 psi minimum shear strength for reliable load-bearing
• Easy installation and removal using a standard 2 mm hex key, reducing assembly time and tool requirements
• Accurate thread engagement with Class 5g6g thread fit ensuring consistent mating with nuts and threaded holes
• Durable mechanical properties from Rockwell B55 hardness, providing excellent wear resistance and longevity
• Regulatory compliance assurance with RoHS 3 and REACH standards, meeting global environmental and safety requirements

Professional Applications & Engineering Value

These M2 shoulder screws are engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 stainless steel material offers excellent corrosion resistance, making them suitable for electronics, medical devices, and automotive components where moisture or chemicals are present. The hex socket drive combined with a knurled head ensures secure tool engagement and prevents cam-out, reducing the risk of damage to sensitive parts. With a coarse thread pitch of 0.4mm, they provide faster installation and higher resistance to loosening under vibration. The precisely machined shoulder maintains consistent spacing in rotating assemblies, bushings, and pivots, eliminating the need for additional spacers and simplifying your B2B mechanical fastening solutions.

Specification Summary & Compliance

This shoulder screw features M2 x 0.4mm coarse pitch threads with Class 5g6g thread fit per metric standards, ensuring tight tolerances for reliable performance. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is -0.05 to 0.05 mm, providing precise dimensional control. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, these screws meet international environmental and safety standards for industrial use.
