Shur-Lok Company

What Shur-Lok Company does

Shur-Lok Company designs and manufactures aerospace-grade mechanical fastening solutions, with a core focus on fluid fittings, locked studs, and specialty inserts. Founded in 1950/1951, the company serves the aerospace, automotive, and space industries, supplying parts that are integrated into safety-critical assemblies where qualification cycles, traceability, and certifiable quality systems are prerequisites to doing business. Operations are anchored by US headquarters in Irvine, California, and supported internationally through Shur-Lok International, based in Petit Rechain, Belgium.

The product portfolio spans barrel nuts, bearing locknuts, expandable diameter fasteners, sandwich panel inserts, fluid fittings, locked studs and inserts, advanced composites inserts, miscellaneous fasteners, and custom engineered fit solutions. The portfolio straddles traditional metallic fastening and the more recent composites-attached product family, indicating an effort to remain relevant as airframe material mix shifts. The company holds Nadcap certification for aerospace quality management, signaling compliance with the industry-specific accreditation regime that governs supplier qualification for major OEM programs. As a subsidiary of Precision Castparts Corp., itself owned by Berkshire Hathaway since 2016, Shur-Lok is embedded within a large aerospace supply-chain platform.

Commercially, Shur-Lok operates as a B2B niche manufacturer selling through the PCC Fasteners distribution channel, with revenue mechanics driven by long-cycle aerospace program qualifications, low-volume/high-spec part production, and engineering-driven custom solutions sold into OEM and Tier 1 customer bases. As a non-public, two-level subsidiary, the company discloses no revenue, headcount, or forward guidance, so observable signals are limited to product-line breadth, certification footprint, and the strategic posture implied by its parent's portfolio decisions.

Products and services

• Barrel Nuts Barrel nuts are specialty blind-threaded fasteners designed to provide load-bearing threads in thin sheets or limited-depth applications. They are engineered for aerospace, space, and automotive OEM assemblies where standard nuts cannot be used.
• Bearing Locknuts Bearing locknuts are precision fastening devices used to secure bearings and rotating components on shafts in aerospace, space, and automotive machinery. They are produced under Shur-Lok's Nadcap-certified manufacturing processes.
• Expandable Diameter Fasteners Expandable diameter fasteners are specialty fasteners that expand after installation to provide secure, vibration-resistant anchorage in thin or composite materials. They are designed for aerospace, space, and automotive structural applications requiring reliable joint integrity.
• Sandwich Panel Inserts Sandwich panel inserts are threaded inserts designed for installation into composite and metal sandwich structures to provide durable, high-strength attachment points. They are used in aerospace and space structures where lightweight panel construction is required.
• Fluid Fittings Fluid fittings are engineered fittings for fluid system connections used in aerospace, space, and automotive applications. They are designed to meet aerospace-grade standards for sealing, pressure, and vibration performance.
• Locked Studs and Inserts Locked studs and inserts are high-strength fastening elements that lock against rotation and provide reliable threaded attachment in demanding structural applications. They are designed for aerospace, space, and automotive customers requiring high-integrity mechanical joints.
• Advanced Composites Inserts Advanced composites inserts are specialty inserts engineered for installation into advanced composite airframe and spacecraft structures. They provide high-strength, lightweight attachment points designed specifically for composite materials.
• Miscellaneous Fasteners Miscellaneous fasteners cover specialty fastening products outside the main catalog families, providing aerospace and industrial customers with single-source access to unusual fastener requirements.
• Custom Fit Innovative Solutions Custom Fit Innovative Solutions is Shur-Lok's custom-engineered fastener development service, providing tailored fastening solutions for unique aerospace, space, and automotive customer requirements that fall outside standard catalog offerings.

Direct peers

• LISI Aerospace: LISI Aerospace is a leading global manufacturer of aerospace fasteners, structural components, and assembly solutions serving major OEMs — directly comparable to Shur-Lok's specialty aerospace fastener business with overlapping product categories (locknuts, studs, inserts) and the same customer base of commercial and defense primes.
• Cherry Aerospace: Cherry Aerospace, a PCC sister company under Precision Castparts Corp., manufactures specialty aerospace fasteners including blind bolts, lockbolts, and pinning fasteners — a directly comparable product portfolio and customer base, with the additional dynamic of being a fellow Berkshire-owned PCC fastener business.

Emerging players

• Bossard Group: Bossard is a global specialist in industrial fastening and assembly technology, with growing aerospace customer penetration and custom-engineered fastening solutions — comparable to Shur-Lok's specialty engineering approach though with a heavier industrial rather than aerospace weighting.

Broad incumbents

• Howmet Aerospace: Howmet Aerospace is a major incumbent aerospace supplier producing fasteners, engine components, and structural parts across commercial aviation, defense, and space — overlapping with Shur-Lok's aerospace fastener portfolio but at vastly greater scale and broader scope.
• Arconic Fastening Systems: Arconic (formerly part of Alcoa) produces aerospace fasteners and structural systems serving major commercial and defense OEMs — comparable product mix of specialty fasteners and inserts with a much larger global footprint than Shur-Lok.
• Stanley Black & Decker (Aerospace Fasteners): Stanley Black & Decker's industrial segment includes aerospace and defense fastening products serving OEMs and MRO — comparable end-market and customer base to Shur-Lok, though within a much larger diversified industrial portfolio.
• Würth Group (Industrial Fasteners): Würth's Industry division supplies specialty fastening and assembly solutions into industrial and transportation markets including aerospace — overlapping with Shur-Lok's custom fastener business but with a far broader product catalog and global distribution footprint.

Regional players

• KLX Aerospace Solutions (part of Boeing): KLX (acquired by Boeing) distributed aerospace hardware and fasteners — overlap with Shur-Lok's product categories and customer base, though the distribution model and OEM-tied positioning differ from Shur-Lok's custom manufacturing focus.
