Key Features & Benefits at a Glance
- Superior corrosion and wear resistance thanks to 18-8 Stainless Steel construction and a durable TiCN coating, extending service life in harsh environments.
- Precise component alignment and location is ensured by the smooth, 6mm diameter shoulder with a precise fit tolerance, minimizing part movement.
- High-strength performance under load with a tensile strength of 70,000 psi and a Rockwell B55 hardness, providing reliable fastening in demanding applications.
- Easy and secure installation with a standard hex socket (3mm drive) and smooth head, allowing for high torque application without slippage.
- Guaranteed interchangeability and fit due to the metric M5x0.8 coarse thread with a Class 6g thread fit, conforming to standard engineering specifications.
- Compliance with major environmental regulations, being RoHS 3 and REACH compliant, making them suitable for use in regulated industries.
Professional Applications & Engineering Value
This precision shoulder screw is engineered to solve critical alignment challenges in machinery and automation. The 10mm shoulder length and precise shoulder fit act as a dowel, accurately locating gears, pulleys, and linkages on shafts while bearing shear loads. Made from 18-8 Stainless Steel and finished with a TiCN coating, it resists galling, corrosion, and wear far better than uncoated fasteners, which is vital for maintenance-free operation in food processing, packaging, and automotive assembly equipment. The Class 6g thread fit and coarse thread pitch ensure quick assembly and a secure hold, reducing installation time and preventing loosening from vibration.
Specification Summary & Compliance
This screw features an M5x0.8 metric coarse thread with a Class 6g thread fit. The shoulder has a diameter of 6mm (tolerance: -0.025 to 0 mm) and a length of 10mm (tolerance: 0 to 0.05 mm) for a precise fit. It conforms to standard metric dimensions and is manufactured to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant.
