Boeing has secured new stocks of fasteners for its 737 MAX jets following a devastating fire at SPS Technologies’ fastener manufacturing facility in February, which threatened to slow down production of the narrowbodies, Reutersreports.

Some fastener manufacturers (possibly Howmet Aerospace and LISI Aerospace) have accepted contracts to provide an alternate supply at higher prices due to rising costs of materials and labor. Prices of essential fasteners, which currently cost hundreds of dollars each, could see double-digit percentage hikes.

A Boeing spokesperson said the company is trying to address fastener shortages but does not expect “a near-term impact to commercial production.”

Following the fire, Boeing faced a shortage of specific nuts and bolts used to attach the landing gear to the aircraft. Historically, Boeing has relied on SPS as the sole supplier of up to 40 parts, including titanium fasteners used to assemble modern aircraft like the Boeing 737 Max, 787 Dreamliner, and Airbus A350.

While Boeing appears to have averted a crippling fastener shortage for now, the SPS fire raises concerns about longer-term supply chain issues many U.S. aerospace companies.

Boeing aims to ramp up production of its fastest-selling narrowbody after last year’s disruption caused other supply chain issues, quality concerns, and a seven-week strike by factory workers. The company aims to produce 42 jets monthly by the end of the year.

Boeing’s fastener supply issue comes amid threats to aircraft prices and delivery times due to the tariffs ordered by the Trump administration. Some nuts were included on a list of critical U.S. items that should not be subject to potential European counter-tariffs, highlighting their importance.
