Shur-Lok Co., A PCC Company

What Shur-Lok Co., A PCC Company does

Shur-Lok Co., A PCC Company designs and manufactures specialized fasteners and fluid fittings engineered for demanding structural and hydraulic applications in aerospace, defense, helicopter, space, and energy end markets. Founded in 1951 in Los Angeles by Frederick W. Rohé and now headquartered in Irvine, California, the company has built a 70-year track record of custom-engineered solutions addressing fastener failure modes that ordinary fasteners cannot resolve, including fretting prevention, vibration-induced loosening, torque retention under high cyclic loads, and operation in extreme pressure and temperature envelopes (fluid fittings certified from -65F to 450F and 3,000 to 8,000 PSI, with up to 24,000 PSI burst on beam seal variants).

The core technology portfolio rests on proprietary mechanical locking and expansion principles rather than commodity threaded fasteners. Product families include Expandable Diameter Fasteners (EDF) using alternating tapered split bushings that expand under compressive load, the Sta-Lok positive locking system using serrated washers and lock rings to prevent rotation and torque preload loss, Ring Locked studs and inserts for high torque-out resistance, advanced composites inserts for fiber-reinforced airframe structures, barrel nuts for high-tensile structural joints, sandwich panel inserts for honeycomb aircraft interior substructures, and bearing locknuts for engine and gearbox applications. Products meet AS9100D, ISO 9001:2015, and Nadcap quality standards, with the European subsidiary Shur-Lok International S.A. (Petit Rechain, Belgium) certified to NF EN 9100:2018.

Shur-Lok operates a quote-based, custom-engineering business model selling primarily to enterprise aerospace and defense primes, including Airbus, Boeing, Safran, GE Aerospace, MTU Aero Engines, Lockheed Martin, BAE Systems, Leonardo, Turkish Aerospace, Airbus Helicopter, Beyond Gravity, OHB, ThalesAlenia Space, and Siemens Energy. Distribution combines direct technical sales ([email protected] / [email protected]), a field engineering team consulted during program design, and the PCC Fasteners distributor network. Revenue mechanics rely on multi-year contracts, customer self-release authorization for direct shipment into production lines, and custom-fit innovative solutions co-developed with OEMs. Since January 6, 2006, Shur-Lok has operated as a wholly-owned subsidiary of Precision Castparts Corp. (NYSE: PCP), providing access to broader manufacturing capabilities and corporate resources.

Products and services

• Barrel Nuts Specialized nuts that minimize drilling and eliminate the need for long expensive bolts when attaching heavy structural members in high-tensile applications such as hanging aircraft engines or attaching wings or tails to fuselage. Includes non-floating standard metallic, non-floating light weight metallic, non-floating non-metallic lockring, and floating metallic variants.
• Bearing Locknuts Bearing locknuts designed for shaft or spindle applications in aircraft engines, gearboxes, and transmissions, featuring the Sta-Lok Positive Locking System and Prevailing Torque Locknuts in advanced aerospace alloys with internal or external threads.
• Expandable Diameter Fasteners (EDF) Custom-engineered fasteners that expand in a hole to prevent fretting, eliminating the need for expensive close tolerance machining or press fits. Product family includes bolts, blind bolts, shafts, clamp-up bolts, pins, handleless cams, and wrap-around cams.
• Sandwich Panel Inserts Inserts potted or mechanically installed in sandwich material like honeycomb to allow fabrication of aircraft interior secondary structures such as stow bins, galleys, and lavatories. Includes threaded or nonthreaded, through or blind, locking or nonlocking variants.
• Sta-Lok Fluid Fittings Hydraulic fittings and fluid adaptors for fuel or fluid systems of aircraft, helicopters, and engines, featuring a serrated lock ring design certified to operate at 3,000-8,000 PSI and temperatures from -65F to 450F, available in titanium and CRES with beam seal, flareless, and flared sealing configurations.
• Locked Studs and Inserts Studs and inserts designed for resistance to high torque-out and pullout loads using a lockring that prevents backing out, ideal for high fatigue and vibration environments in gearboxes, turbo machinery, and vehicles for aerospace and military markets.
• Advanced Composites Inserts Special fasteners for fiber-reinforced advanced composites addressing localized concentrated loading, galvanic compatibility, interference fit, edge crushing, vibrations, and water absorption, including bonded-on, bonded mechanical, and nonmetallic potted-in types.
• Miscellaneous Fasteners Fasteners designed to reduce vibration, noise, and heat transfer to aircraft interiors, including isolator mounts with neoprene or silicone rubber and metal, blind inserts for sheet metal applications, and special inserts for sheet metal, wood, or sandwich structures.
• Custom Fit Innovative Solutions Custom fastening solutions co-developed with customers for new programs with engineering challenges or existing programs requiring cost reduction without compromising quality, focused on weight saving, high locking torque resistance, and best fit serrations.

Direct peers

• Cherry Aerospace: Sister company within Precision Castparts Corp.'s fastener portfolio, specializing in blind bolts, blind rivets, and blind fasteners for aerospace and defense. Directly comparable product mix and shared distribution through PCC Fasteners, though it focuses on blind-fastener technology rather than Shur-Lok's locking and EDF solutions.
• TriMas Aerospace: Aerospace division of TriMas Corp., producing proprietary fasteners, blind bolts, and engineered components for aerospace and defense applications. Comparable mid-sized specialty fastener competitor serving similar airframe and engine OEM customers.
• LISI Aerospace: French-headquartered global leader in aerospace fasteners and structural components, with overlapping product families (bolts, screws, locknuts, inserts) and a similar Tier-1 aerospace OEM customer base including Airbus, Boeing, and Safran. LISI is the most direct global competitor to Shur-Lok in proprietary aerospace fasteners.
• SPS Technologies: Another PCC-owned aerospace fastener subsidiary (high-strength bolts, nuts, and lockbolts for airframe and engine applications). Direct competitor for many of the same Boeing/Airbus engine and structural programs; operates within the same parent as Shur-Lok.

Broad incumbents

• Howmet Aerospace: Large-cap aerospace supplier whose Fastening Systems segment produces aerospace bolts, screws, and rivets for engine and airframe applications. Significantly larger and more diversified than Shur-Lok but competes in the same high-spec aerospace fastener category with comparable OEM customers.
• B/E Aerospace (Safran Cabin): Now part of Safran's Cabin division, B/E Aerospace manufactures aircraft interior structures that use sandwich-panel inserts — directly adjacent to Shur-Lok's Sandwich Panel Inserts product family used in galleys, lavatories, and stow bins.
• Illinois Tool Works (Aerospace segment): Diversified industrial manufacturer with an aerospace segment supplying engineered fasteners and components. Broader portfolio than Shur-Lok but overlaps in select high-spec aerospace fastener categories, particularly for engine and structural applications.

Emerging players

• Click Bond: Specialty adhesive-bonded fasteners and studs for aerospace and defense structural applications. Overlaps with Shur-Lok's Advanced Composites Inserts line and serves the same OEMs seeking weight-saving fastening solutions for composite airframes.
• Lakside Industries: Smaller specialty aerospace fastener manufacturer producing inserts, studs, and engineered fastening solutions for airframe and engine applications. Comparable in size to a single Shur-Lok product line and serves a similar niche OEM customer base.

Regional players

• Vossloh Fastening Systems: German-headquartered fastening systems provider with a smaller aerospace exposure compared with rail, but supplies engineered fasteners and locking solutions to European aerospace OEMs. Regional overlap with Shur-Lok International's European customer base.
