Notes for Attention
Surface damage indication:
The serrated flange nuts will bite into the surface of the workpiece during tightening, which may cause indentation or minor damage on the contact surface. If the workpiece surface has specific appearance requirements or is not allowed to have scratches, it is recommended to use smooth flange nuts without serrations (DIN 6923 serration-free type).
Do not use simultaneously with the gasket
Since the flange surface already has the function of a gasket, and the teeth need to directly contact the workpiece to achieve the anti-loosening effect, please do not use this product together with flat washers. Otherwise, it will affect the anti-loosening performance and the function of the flange.
Specification Matching Confirmation
Before installation, please ensure that the thread specifications of the nuts and bolts are consistent (metric coarse thread). Avoid connection failure caused by mismatched specifications. For example, an M6 nut should be paired with an M6 bolt.
Torque Control
It is recommended to operate using a torque wrench and follow the standard tightening torque. Excessive force should be avoided to prevent damage to the nut or thread slippage.
Regular Inspection
When used in corrosive environments or under high-frequency vibration conditions, it is recommended to conduct regular inspections of the tightening status and corrosion condition of the nuts, and replace them in a timely manner to ensure safety.
Storage conditions
Store in a dry and ventilated environment to prevent rust caused by moisture. Although 304 stainless steel has excellent corrosion resistance, it is still recommended to maintain a clean and dry storage environment.
Pre-installation Inspection
Before installation, please check the appearance quality of the nuts. If there are any obvious defects (such as cracks, deformations, etc.), do not use them.
Torque Calibration for Critical Areas
When using critical connection areas, it is recommended to perform torque calibration to ensure the reliability and safety of the connection.
