Tips for investigating a Fastener Problem:
Get as much information as possible:
- Where and how are the parts used?
- Have you bought these parts for a long time?
- Are you the sole customer of this part?
- Request samples of failed parts
- Are unused parts available from the same lot? If yes, request some.
- How many parts are used in the assembly?
- Is there any pattern to the failures – for example, are they failing in a single location?
- What type of driver is being used?
- What torque value is being used to install the parts?
- Request pictures of failed parts and the assembly
- If possible, allow the supplier to visit and observe the problem first-hand.
- How best would you describe the problem?
- Has anything recently changed or something unique occurred?
Tunable torque design allows screws to be shipped in the “Field Ready” position.
