Unmanned Systems
Unmanned systems span aerial drones (UAV/UAS), ground vehicles (UGV), and maritime platforms serving commercial, industrial, and defense missions.

Fastening Solutions for Drones Aerial, Ground & Maritime
These platforms live or die on payload margin and reliability, where every gram of fastening hardware trades directly against flight time, range, or payload capacity, and where assemblies face sustained vibration, shock loading, thermal cycling, and moisture or salt exposure. Our engineered fastening solutions reduce mass and part count while holding secure under field conditions, and are designed for manufacturing scalability.
- microPEM® solutions for compact joints and lightweighting.
- Custom solutions with PEM® Application Engineering and Testing support for purpose-engineered fastening with Design for Manufacturability focus.
- Threaded inserts and SMT fastening solutions for flight controllers, avionics, and sensor PCBs
- Broaching and self clinching technology for sheet-metal and cast for structures.
- Vibration- and shock-resistant fastening for motor mounts, gimbals, and propulsion assemblies.
