PEM® BF™ and BFS™ Fine Finish Blind Nuts
PEM® BF™ and BFS™ Fine Finish Blind Nuts
Engineered for Sensitive Applications Where No Metal Chips Can Be Risked
Burr-free fastening engineered for electrical safety in sensitive applications.
In conductive high-voltage applications, microscopic burrs left by conventional machining act as field concentrators – where voltage crowds, breakdown thresholds drop, and arcing can occur.
PEM® BF™ and BFS™ Fine Finish self clinching blind nuts engineered to be inherently burr-free to deliver a cleaner conductive surface, a higher dielectric breakdown margin, and dependable performance in high potential testing and in service.
Burr-Free by Design
The Fine Finish manufacturing process eliminates microscopic burrs to remove the field concentration points that create risk in conductive applications.
Predictable Dielectric Performance
Get a cleaner fastener surface for a higher, more consistent dielectric breakdown margin – and more reliable high potential testing results.
Thread and Component Protection
Closed-end design seals threads against foreign matter and contamination, and limits screw penetration depth to protect sensitive internal components.
Reliable in Soft Materials
Larger flange design delivers greater bearing surface for secure thread retention in soft copper and aluminum busbar panels with no damage or deformity to material.
Permanently Mounted
Installs permanently using HAEGER® or PEMSERTER® machine tooling.
