- Secure, non-slip manual adjustment enabled by the knurled head texture for easy handling.
- Reliable, standardized fit ensured by the M5 x 0.8mm coarse thread with Class 5g6g tolerance.
- Durable, long-lasting service life supported by a Rockwell B83 hardness rating.
- Confident global sourcing with compliance to ISO 7379, RoHS 3, and REACH standards.
Professional Applications & Engineering Value
This M5 shoulder screw is engineered to solve critical alignment and pivot point challenges in industrial assemblies. The 12mm shoulder length provides a precise bearing surface, eliminating the need for separate spacers or bushings and reducing assembly time and component count. Manufactured from 18-8 stainless steel, it offers excellent resistance to rust and corrosion, making it suitable for food processing, packaging machinery, and outdoor equipment. The knurled head allows for tool-free adjustments in applications like conveyor systems or optical mounts, while the hex drive ensures high torque capability for secure fastening. Its high tensile strength ensures reliability in dynamic applications where vibration and shear forces are a concern.
Specification Summary & Compliance
This precision metric shoulder screw features an M5 thread with a 0.8mm coarse pitch and a Class 5g6g thread fit for consistent engagement. The shoulder diameter is 8 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, ensuring exact positioning. The product is manufactured in accordance with ISO 7379 and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
