Every gram saved
is payload.
In an eVTOL or long-range UAV, fasteners are not hardware - they are airframe. Light-alloy joints decide range, payload and safety margin, and they must come with strength data, not promises.
Aerospace thinking, automotive economics
Magnesium and carbon structures corrode against steel; joints must hold through vibration, thermal cycles and hard landings; and every gram of fastener mass is paid for in battery cells. We bring aircraft-grade joint logic - material matching, documented strength, surface protection - to production economics that make sense for fleets, not prototypes.
- ZT68 aluminum bolts - steel-class strength at ~65% lower mass
- Elongation ≥8% - joints that deform rather than shatter under crash loads
- Rivet nuts for sandwich panels and closed profiles, installed from one side
- Documented per-batch strength and surface data for airworthiness files
Where light-alloy joints fly
UAV frames & propulsion mounts
Aluminum bolts matched to carbon and magnesium structures, with isolation where dissimilar metals must meet.
eVTOL structures & battery boxes
Light, tough joints with the traceability documentation certification demands.
Ground support & tooling
Custom sleeves, pins and fixtures built to airframe tolerances.

Yes. Mechanical test reports and surface-treatment records accompany production lots, so every joint in the airframe file traces back to tested hardware.
Carbon is cathodic to almost every metal, so we pair aluminum bolts with isolation strategies - coatings, sleeves and washer systems - and prove the combination in salt-spray testing rather than assuming it.
That is our home ground: send the drawing and loads, and we will propose a cold-heading-based route that hits the mass target at production cost.
Designing an airframe that steel fasteners ground?
Send the joint list, loads and mass budget - our engineers will answer with material, finish and documentation to match.
