From Stanley Engineered Fastening - Spiralock
Failure is not an option when it comes to medical equipment. From critical or sensitive devices like lasers, MRI scanners, knee joints, and implantable pacemakers to instruments as straightforward as stethoscopes, when life or quality of life is at stake, medical equipment must be reliable.
In the medical field there's little room for the $15 billion per year spent by 25 of the largest US manufacturers on warranty claims; and little room for processing those claims that eat up 2.5% to 4.5% of revenues for companies across all industries. The industry has higher aims than other fields and customer satisfaction and warranty problems associated with fastener failure must be prevented or quickly and economically handled.
Due to medicine's working environment inside and outside the human body, fasteners such as C-clips and specialized retaining rings can prove too cumbersome and costly. Because repetitive loads, shock and vibrational loosening must be decisively handled, traditional fasteners susceptible to self-loosening rotational movement, stripping, and shearing are not always appropriate either.
Products & Services
Locknuts
Locknuts are a type of prevailing-torque fastener that resists loosening under vibration and torque. They differ from standard nuts because they typically have friction-increasing bearing surfaces (e.g., pitted grooves on flanges) or special internal thread-geometries.
Captive Fasteners
Captive fasteners are designed for permanent retention within their target assembly or housing, often even upon servicing, providing a secure joint and avoiding loss or damage that might be caused by a loose part.
Threaded Inserts
Threaded inserts are blocks of material with a threaded hole that are pressed or molded into a part, usually made of a different material.
Nuts
Nuts are a type of hardware fastener with a tapped inner diameter. They are used with a mating threaded bolt or rod to secure components. There are many sizes and varieties of nuts; each with a particular fastening purpose. Some nuts can be applied without tools, and others may have special designs to prevent the nut from loosening.
