Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address critical alignment and pivot point challenges in industrial machinery. The 316 Stainless Steel material provides exceptional resistance to corrosion from chemicals and moisture, making it ideal for food processing, marine, and chemical equipment. The precision 12mm shoulder diameter acts as a built-in spacer or bearing surface, eliminating the need for additional components and reducing assembly time. The hex socket drive with a knurled head ensures high-torque installation without cam-out, while the Class 5g6g coarse thread offers rapid assembly and reliable performance in high-vibration environments. This combination delivers long-term reliability and reduces maintenance cycles in precision shoulder bolt applications.
Specification Summary & Compliance
This shoulder screw features an M8x1.25 metric coarse thread with a Class 5g6g thread fit for standard industrial applications. The shoulder diameter is 12 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 12 mm with a tolerance of 0 to 0.25 mm. The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring it is free from hazardous substances and suitable for global markets.
