When it comes to medical device manufacturing, the qualities of individual components affect the durability and functionality of your products. Fasteners are responsible for connecting the stainless-steel hardware or polymer components of your design. Before you select these parts, however, there are many factors to consider to ensure you have the right types for your device.

What to Consider When Selecting Fasteners

1. Damage Resistance

If the medical device will be subject to frequent transport, handling, or load bearing, it will be vulnerable to scrapes and scratches. As a result, you’ll need to choose fasteners with hardy finishes. Soft or flexible fasteners will be more susceptible to damage or corruption. Larger options are also generally sturdier, as smaller parts like countersunk screw heads have an increased risk of stripping the socket.   

2. Corrosion Impact 

Corrosion resistance is one of the most critical features to look for in fasteners for medical devices. Rusting or staining will shorten the lifespan of the device and affect its functionality. Consider the conditions that the device will be exposed to so you can choose the right fasteners. For instance, fasteners can be sealed with finishes like zinc that can withstand occasional condensation or abrasion. 

3. Tight Tolerance

Self-clinching fasteners must be harder than the panel material to ensure adequate and tight clinching. This prevents any issues with loose or missing hardware and simplifies the process for secondary repairs. Along with tightening tolerance, fasteners must also be strong enough to withstand loading and vibration. Talk to your producer about custom solutions to test during the medical device manufacturing process.
