祝福锻造卷怎么不能用:我需要找人求助翻译

While the traditional threaded fastener
is often assumed to be a cost-effective
fastening solution for underbody
panels and engine covers, overall costs
increase when the time and labor charges
to service the vehicle are factored into
the overall equation. Quick-access fasteners,
though having a higher initial
piece cost, increase productivity during
the service and maintenance procedures
carried out on the vehicle. They cut disassembly
and reassembly times when the
underbody shield is removed to service
the protected parts.
Unlike a threaded fastener, a quarterturn
fastener does not require an assembly
tool with torque control. If a screw is
not tightened properly with specifi ed
torque, it can work loose because of vibration.
The quarter-turn fastening system
will absorb vibration due to the spring
defl ection in the receptacle. The positive
locking feature of these fasteners can reduce
insurance claims, warranty replacement,
and public liability for both consumers
and manufacturers by limiting
damage and loss of the fastened parts.
Quick-access fasteners meet automotive
corrosion and fl ammability specifi cations,
are RoHS (Restriction of Hazardous
Substances) compliant, and securely lock
the underbody shield into place while remaining
reliable and mechanically simple.
