What Makes a Quality Rivet?
So what exactly makes one rivet superior to another? Here are some of the key factors that contribute to a rivet being deemed high quality:
Material - Aircraft-grade aluminum is the gold standard when it comes to rivet material. Grade 2 titanium and copper alloys also make excellent rivets. High carbon steels can be used but may corrode over time.
Strength - A quality rivet must be able to withstand shearing and tension forces involved in joining materials. The rivet should fail only when the underlying materials fail.
Durability - Quality rivets maintain their strength and integrity over years of use without loosening, warping or corroding.
Precision - Dimensions of the rivet shank, head, and point must be precise and uniform. Even minor deviations can impact performance.
Manufacturing - Rivets made with tight CNC machining tolerances outperform mass produced fasteners. Clean machining without burrs or cracks is vital.
Testing/Certification - Reputable rivet manufacturers repeatedly test products and back claims with certifications like ISO 9001.
Why Rivet Quality Matters for CNC Work
CNC projects rely on rivets for structurally securing wooden, plastic, or metal materials together in a flawless finished product. But utilizing poor quality rivets can compromise the safety and longevity of CNC creations in several ways:
Joint Failure - Inferior rivets are more prone to shear failure at joints leading to catastrophic disasters like a cabinet collapsing.
Loosening Over Time - Low quality rivets loosen over repeated loading leading to wobbly joints and future failures.
Material Damage - Subpar rivets made of improper materials can actually damage the base material when overtorqued or exposed to moisture.
Project Aesthetics - Poorly machined rivets detract from the seamless professional aesthetic expected of CNC work.
Replacement Difficulty - Rivets that fail after assembly may be impossible to access and replace on intricate CNC products.
By using top-grade rivets matched appropriately to your base materials, CNC creations will last for years with riveted connections that are dependably tight, sheer-resistant, and corrosion-free.
Tips for Working with Quality Rivets
Once you’ve sourced high quality rivets for your CNC projects, proper techniques are needed to get the most out of your hardware:
Use rivet nuts - For bolted connections, rivet nuts improve load distribution and reduce spin out risk.
Mind edge distance - Allow ample margin between rivet holes and edges to prevent tear out.
Deburr holes - Use a countersink bit to deburr and slightly chamfer rivet holes for easier insertion.
Secure workpiece - Clamp materials to drill/drive rivets in a completely fixed setup free of vibration.
Match drill bit - Size your drill bit precisely to the rivet shank diameter to optimize fit.
Check grip length - Choose rivet length to properly fill but not exceed the combined material thickness.
Use quality washers - Hardened washers prevent rivet heads from digging into soft materials.
Set with care - Use manufacturer recommended force and technique to set rivets snugly but avoid damage.
Inspect setting - Ensure rivet forms a neat head without shank cracks or material dimples.
Seal if needed - Seal exterior rivets with adhesive or paint to prevent material seepage and corrosion.
Troubleshoot issues - Investigate the root cause if rivets work loose or fail unexpectedly.
By starting with ultra-precise quality rivets and properly integrating them into your CNC assemblies, you can have total confidence in the structural security of your finished products.
