SIST EN 2792:2001

Aerospace series - Rod ends, adjustable, double fork and threaded shank with engagement: 1,5 x thread diameter - Dimensions and loads

This standard specifies the characteristics of adjustable rod ends consisting of: - Double fork - a threaded shank comprising: - a circumferential groove to identify engagement; - an optional longitudinal groove for locking purposes. These rod ends are intended for use with flight control rods or rods for aircraft structures. The cadmium plating restricts the application to temperature not exceeding 235°C

Luft- und Raumfahrt - Einstellbare Doppelgabelköpfe mit Gewindeschaft mit Einschraubtiefe von 1,5 x Gewinde-Durchmesser - Maße und Belastungen

Die vorliegende Norm legt die Eigenschaften von einstellbaren Gabelköpfen fest.Diese Gabelköpfe bestehen aus : - einem Doppelgabelkopf; - einem Gewindeschaft, der -mit einer Ringnut zur Kontrolle der Einschraubtiefe versehen ist; -eine Längsnut zur Sicherung aufweisen kann. Sie sind für Bediengestänge für Flugsteuerungen oder für Strukturstangen von Luftfahrzeugen bestimmt. Die Kadmierung schränkt die Anwendung auf Temperaturen bis 235°C ein.

Série aérospatiale - Embouts réglables a chape double et a tige filetée a implantation: 1,5 x le diametre de filetage - Dimensions et charges

La présente norme spécifie les caractéristiques des embouts réglables consitués:- d'une chape double; - d'une tige filetée comprenant: - une gorge circulaire de repérage d'implantation; - éventuellement une rainure longitudinale de verrouillage. Ces embouts sont destinés aux bielles pour commandes de vol ou aux bielles de structures d'aéronefs. Le cadmiage réduit leur utilisation à une température ne dépassant pas 235°C.

Overview - EN 2792:1991 (Aerospace series)

EN 2792:1991 is a CEN aerospace standard that defines the dimensions and load characteristics for adjustable rod ends with a double fork and a threaded shank having an engagement depth of 1.5 × thread diameter. The standard covers identification and locking features-specifically a circumferential groove to identify engagement and an optional longitudinal groove for locking-and limits the use of cadmium plating to environments up to 235 °C. These rod ends are intended primarily for flight control rods and other aircraft structural linkages.

Key topics and technical requirements

• Geometry and dimensions: standardized form and size parameters for double-fork rod ends to ensure interchangeability and correct fit with mating components.
• Threaded shank engagement: specification of engagement length equal to 1.5 × thread diameter, used to define correct screw-in depth and mechanical retention.
• Identification groove: circumferential groove requirement to mark engagement condition for inspection and assembly.
• Locking provision: optional longitudinal groove for mechanical locking methods (wire, cotter, or other locking devices where applicable).
• Surface treatment limits: use of cadmium plating allowed but restricted to service temperatures ≤ 235 °C, important for corrosion protection and high-temperature performance.
• Loads and performance: the standard provides load-related guidance and design limits for safe use in aerospace control and structural systems (see full text for numeric values and test criteria).
• Intended applications: explicit focus on aircraft flight control rods and structural rod connections.

Applications and who uses EN 2792:1991

• Aerospace design engineers specifying rod-end hardware for flight control linkages and structural actuation systems.
• Manufacturers producing adjustable rod ends and mating components to ensure dimensional conformance and interchangeability.
• Procurement and quality assurance teams verifying parts against an accepted standard for aircraft components.
• Maintenance, repair and overhaul (MRO) organizations selecting replacement rod ends that meet original equipment requirements.
• Certification and regulatory bodies referencing standard dimensions and material/finish limits during conformity assessments.

Related standards

• Published by CEN as part of aerospace series; users should consult other EN/ISO aerospace fastener and surface-treatment standards for complementary requirements (e.g., fastener thread standards, material specifications, corrosion protection).
• The full standard document (EN 2792:1991) should be obtained from CEN or national standards bodies for exact dimensional tables, load values, test procedures, and implementation details.
