S-90269A524 M4 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and chemical exposure
• Enhanced durability and wear resistance from Rockwell B79 hardness and black oxide finish, extending service life
• High mechanical strength with 70,000 psi tensile and 35,000 psi shear strength for demanding load applications
• Precise alignment and spacing ensured by the 15mm shoulder length and 5mm shoulder diameter with tight tolerances
• Secure, non-slip installation using the 2.5mm hex drive and knurled head for improved grip and torque application
• Reliable thread engagement with Class 5g6g metric coarse thread fit, reducing cross-threading risks
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries

Professional Applications & Engineering Value

This M4 shoulder screw is engineered to solve critical alignment and durability challenges in industrial assemblies. The 316 stainless steel material provides exceptional resistance to corrosion from moisture, chemicals, and salt spray, making it suitable for marine, food processing, and outdoor equipment. The 15mm shoulder length and precise 5mm shoulder diameter act as a pivot or spacer, ensuring accurate component positioning in machinery, robotics, and conveyor systems. Combined with the black oxide finish, it reduces galling and offers mild lubricity for easier installation. The hex drive socket head and knurled texture allow for high-torque applications without slippage, while the Class 5g6g thread fit guarantees consistent fastening in metric coarse threaded assemblies, minimizing downtime and maintenance costs.

Specification Summary & Compliance

This shoulder screw features an M4 x 0.7mm metric coarse thread with Class 5g6g thread fit for precise tolerance. The shoulder diameter is 5 mm with a tolerance of -0.072 to -0.01 mm, and shoulder length is 15 mm with a tolerance of 0 to 0.25 mm, ensuring exact fit in precision applications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances and suitable for global industrial use.
