Why do set screws loosen?
Common reasons for set screw loosening include:
Vibration or impact causes the thread to lose bite.
The thread clearance is too large or locking structure (such as thread glue) is not used.
The torque applied is insufficient, resulting in insufficient clamping force.
Solution:
Use auxiliary locking tools such as thread glue or spring washers.
Check the thread specifications to ensure that the tolerances match.
Tighten the screws according to the recommended torque value.
Why do set screws easily strip or break?
The reasons for stripping or breaking may include:
The material used is not hard enough or of poor quality.
Overtightening causes thread damage or stress concentration.
Using unsuitable tools or methods.
Solution:
Choose high-quality set screws, giving priority to products that meet standards.
Use a torque wrench to avoid excessive force.
Make sure the tool size matches the screw specifications.
Why can't the set screw firmly fix the workpiece?
The screw is not long enough to fully contact the workpiece.
The mounting surface is oily or impurities, causing sliding.
The thread precision is low, resulting in loose fit.
Solution:
Make sure to choose a set screw of suitable length, and try to make the thread engagement part not less than 1.5 times the screw diameter.
Clean the surface of the workpiece to remove oil and impurities.
Replace a screw with higher precision to ensure good thread fit.
Why is the anti-rust performance of the set screw poor?
Insufficient surface treatment and low corrosion resistance.
The use environment is too humid or in contact with corrosive chemicals.
Not regularly maintained or lubricated.
Solution:
Choose products treated with black zinc, electrogalvanized or rust-proof coating.
Apply anti-rust oil or lubricant after screw installation.
Avoid the set screw from being directly exposed to a corrosive environment.
Why is it found that the set screw cannot be tightened or slips after installation?
The thread part does not match the size of the mounting hole, and the tolerance is too large.
The thread inside the mounting hole is damaged or worn.
The screw itself has quality problems (such as surface defects or processing errors).
Solution:
Check the size and state of the mounting hole thread, and re-tap if necessary.
Replace the set screw with a high-precision one.
If the hole diameter is too large, use a thread repair tool or thread kit to repair it.
Why does the set screw break or become difficult to remove when it is removed?
Long-term use causes the screw to rust or stick.
Over-tightening during installation causes stress concentration.
Improper tool selection or uneven force.
Solution:
Soak with rust inhibitor for a period of time before removal to reduce resistance.
Use appropriate tools (such as a hex wrench or screw extractor).
If the screw breaks, try drilling a hole with an electric drill and removing it with a thread repair tool.
