Fastener pins prevent locking
Follow proper usage
The length of the bolt should be selected appropriately, subject to 1-2 pitches of the nut exposed after tightening.
The tensile strength of the bolt and the safe load of the nut meet the design requirements
Use the product to clean the thread before use. If the thread is bumped, at least the nut can pass smoothly.
When tightening the nut, the direction of force applied by the wrench must be perpendicular to the axis of the bolt and must not be inclined.
Use a torque wrench, avoid using an electric wrench, the torque value is within the safe torque range (refer to the low box of the product package), and the force is evenly applied during the rotation.
