The importance of fastener torque auditing and certification

Any electronic device, old or new, contains several screws and bolts.
For these products to meet the promised specifications, consistent torque
application on the screws and bolts is critical. An improperly torqued screw
can mean the difference between certification success and product failure. Measuring
the resulting bolt loading is an accurate method to ensure your process is
applying the necessary torque.

Gasket and seal integrity
validation

New regulations require many consumer products to be compliant with appropriate
IP ratings, which means seal and gasket integrity of the finished product is
crucial. Seal failure can impact the project resulting in lost time and money.
Incorporating bolt and screw torque auditing into both manufacturing and
quality assurance processes helps mitigate and reduce failures from improperly
torqued fasteners.

3rd party repair certification

Advertising repair services, obtaining technical drawings, and
purchasing hardware components require certifications from the manufacturer.
These certifications will often require the repair facility to conform to and
ensure that each screw or bolt has the same torque applied to them as indicated
by the manufacturer’s design documents.

Standards compliance and
traceability

When you are subject to FAA regulations, FDA regulations, ISO standards
or internal standards, it’s important to ensure verification and traceability
of a product’s conformance to specifications. In many of these cases, every
critical component down to the torque applied to the fasteners and their material
make-up, must be traceable. Incorporating a driver with built-in torque sensing
enables logging of applied torque to all fasteners and allows for quality
assurance to double-check critical areas.

Regardless of the product you are manufacturing – be it a smartphone, pacemaker,
or watch – you will need to ensure every fastener receives the correct amount
of torque. This requires a torque sensor, which is either coupled to or
integrated directly into a driver. A display and data logger is also required
so that the operator knows the exact torque that is being applied to the
fastener, while also providing traceability records.

Improve the reliability of your products and get a clearer picture of the
loads applied to your system by combining torque validation with bolt loading
validation.
