Pilgrim Aerospace Fasteners

What Pilgrim Aerospace Fasteners does

Pilgrim Aerospace Fasteners (legal entity Pilgrim Screw Corporation, d/b/a Pilgrim Aerospace Fasteners) is a precision aerospace fastener manufacturer headquartered in Chandler, Arizona, with operations consolidated to a single facility since 2017. Founded in 1932 in Providence, Rhode Island originally as a jewelry screw supplier, the company pivoted into defense manufacturing during World War II and has since built a 90-plus-year catalog of bolts, screws, clevis pins, and solid/semi-tubular rivets manufactured to NAS, MS, AN, and AS aerospace and military specifications, including titanium alloy screws and OEM-licensed "Approved Specials" for Boeing, Airbus, Bombardier, BAE Systems, Bell, Honeywell, Sikorsky, and Rafael. Core production capabilities span hot heading, cold heading, CNC machining, and in-house tool and die making, supported by AS9100-2015, ISO 13485:2016, ISO 9001, ITAR, DFARS, and JCP certifications.

The company sells direct to enterprise aerospace, defense, medical, and space customers through an enterprise field sales motion — dedicated phone line, sales email, and a web-based Request for Quote process — with quote-based, multi-year contract pricing. Customers include Boeing, Lockheed Martin, Airbus, Raytheon, Honeywell, Bombardier, Sikorsky, and NASA (notably the Mars Rover program). In January 2024, Japan-based MEIDOH Co., Ltd. acquired Pilgrim, integrating it into the Meidoh Group, which extends distribution reach into Japan, Thailand, China, Germany, Israel, and South America; in June 2026 Pilgrim added a strategic asset management partnership with AvAir for surplus OEM inventory distribution. Pilgrim operates 101-250 employees under an EOS (Entrepreneurial Operating System) framework with an active Board of Directors, and was recognized as a Chandler 100 company in 2025.
