Boeing, one of the world’s two largest aircraft manufacturers, recently posted stronger-than-expected earnings and signaled further increases in aircraft deliveries, injecting fresh momentum into the global aerospace supply chain. Riding that wave, National Aerospace Fasteners Corporation (Nafco), a Tier-1 supplier of engine fasteners to Boeing, is accelerating its capacity expansion. The company has broken ground on the second phase of its Malaysia facility, scheduled for completion in the fourth quarter of 2027—underscoring a striking reality, executives say: the biggest challenge is no longer demand, but production capacity.
