AN123154 - PW&C Universal Head Solid Rivet .062 × .312

AN123154 – Pratt & Whitney Canada OEM Universal Head Solid Rivet (2-5 Size)

Available now on the Airparts.aero Marketplace.

Overview

The AN123154 is a solid structural rivet manufactured to a proprietary Pratt & Whitney Canada (P&WC) specification for use in the assembly and repair of their turbine engines. The universal head style conforms to the standard AN470/MS20470 profile, and the specified dimensions of .062 x .312 inches correspond to the standard aviation rivet size code of 2-5 (2/32" diameter by 5/16" length). This is a flight-critical piece of hardware used to create permanent, high-strength joints in engine components.

As a genuine P&WC OEM part, this rivet is manufactured from a specific material alloy chosen by the engine's design engineers for its unique strength, shear, and thermal characteristics required at its designated location within the engine. Unlike general-purpose airframe rivets, the material of an engine rivet is a critical, non-substitutable attribute essential for the engine's structural integrity and operational safety. The precise material for this part number must be verified by the applicable engine maintenance documentation.

Key Features

• Genuine Pratt & Whitney Canada OEM Part: Guarantees the rivet is manufactured to the exact material and strength specifications required for a certified P&WC engine.

• Universal Head Style: The AN470/MS20470 head profile provides an excellent combination of strength and low aerodynamic drag.

• Solid Rivet for Driven Installation: Engineered to be installed using a rivet gun and bucking bar, a process which swells the shank to completely fill the hole, creating a superior, high-strength friction joint.

• Standard 2-5 Size: Conforms to the standard dimensional callout for a 2/32" diameter, 5/16" length rivet.

• Application-Specific Material: The material alloy is specified by P&WC for a particular thermal and stress environment within the engine, a critical feature for hot-section or firewall applications.

Technical Specifications

• Part Number: AN123154

• Component Type: Solid Rivet, Universal Head

• OEM Manufacturer: Pratt & Whitney Canada (P&WC)

• Governing Specification: P&WC Engineering Drawing 123154

• Head Style: Universal (conforms to AN470 / MS20470 profile)

• Diameter: 2/32 inch (0.0625 inches)

• Length (under head to end): 5/16 inch (0.3125 inches)

Aircraft Compatibility

This is not an airframe-specific part, but an engine-specific component. Its applicability is determined by the Pratt & Whitney Canada engine model, serial number, and the specific component being assembled or repaired. It may be used on a variety of P&WC engines, including models from the PT6A, JT15D, or PW500 series.

Note: Verification of applicability is the absolute responsibility of the installer. The engine's current Illustrated Parts Catalog (IPC) is the final authority for confirming part number eligibility.

Applications

• Permanent structural assembly of turbine engine components.

• Attaching engine baffles, brackets, cases, shrouds, and firewalls where a solid, driven rivet of this size and specific material is required by the manufacturer's engineering drawing.

Why Choose AN123154?

Rivets used within a certified turbine engine are not generic hardware. The material alloy is precisely selected for its shear strength, fatigue life, corrosion resistance, and performance at the extreme temperatures found within the engine. Using the genuine P&WC OEM part is the only way to guarantee the correct, certified material is being installed. Substituting an incorrect material—such as an aluminum alloy rivet in a location requiring Monel—will lead to the rapid and catastrophic failure of the rivet and the joint it secures.

The engineering principle of a driven solid rivet joint lies in creating both a mechanical interlock and a high-integrity friction joint. During installation, the pneumatic rivet gun delivers a series of high-energy impacts to the factory head, while a steel "bucking bar" is held against the tail. This process forces the ductile rivet material to flow, forming the "shop head" and, critically, causing the rivet's shank to swell radially. This shank expansion, known as "hole-filling," ensures there are no gaps between the rivet and the hole walls. The subsequent cooling of the rivet as it normalizes also induces a significant tensile stress, which provides a powerful clamping force on the joined materials. This combination of mechanical shear strength from the rivet itself, the clamping force, and the friction between the sheets makes a properly driven solid rivet an exceptionally strong and fatigue-resistant joining method.

Note: This is a flight-critical, single-use hardware component. Installation must be performed by a certified A&P technician with structures experience, in strict accordance with the engine manufacturer's Standard Practices Manual or other approved repair data. Correct hole preparation (drilling, deburring), rivet material identification, and the use of the proper rivet gun set and bucking bar are all critical for an airworthy repair. The formed shop head must be inspected for correct dimensions and the absence of cracks.
