SIST EN 2942:2001 is a Slovenian standard published by SIST. It specifies self-locking, helical coil, screw thread inserts made from heat resisting nickel base alloy NI-PH2801 (Inconel X750) with silver plating for aerospace applications, and it sets a maximum test temperature of 550°C. Engineers, quality staff and buyers use it to identify the required insert type and the material and finish expected for this aerospace fastener.
What does SIST EN 2942:2001 specify?
SIST EN 2942:2001 specifies the characteristics of self-locking, helical coil, screw thread inserts in NI-PH2801 (Inconel X750), silver plated, for aerospace use. In practice, that means the standard is for selecting and supplying one defined insert type rather than a general fastener family.
The scope is focused on one product configuration:
- self-locking function
- helical coil form
- screw thread insert application
- heat resisting nickel base alloy NI-PH2801 (Inconel X750)
- silver plated finish
- maximum test temperature of 550°C
That combination matters because the user needs a part that keeps its locking behavior and identified material condition in aerospace service, including elevated-temperature testing up to the stated limit.
What are the key requirements of SIST EN 2942:2001?
SIST EN 2942:2001 centers on the defined product characteristics that suppliers, inspectors and purchasers should use when specifying these inserts. The main technical points in the title and scope are the ones that matter most for practical selection and verification.
Product type and function
SIST EN 2942:2001 covers self-locking, helical coil, screw thread inserts. In practice, that tells the reader the part is not a plain insert - it is a coil-style threaded insert with a locking feature intended to help the assembly retain thread engagement in service.
Base material
SIST EN 2942:2001 requires the insert to be made from heat resisting nickel base alloy NI-PH2801 (Inconel X750). For procurement and quality checks, this means the alloy designation is part of the product identity and should be controlled when ordering, receiving and certifying parts.
Surface finish
SIST EN 2942:2001 specifies silver plated inserts. That matters because the plating is part of the defined configuration, so buyers and inspectors need to treat the surface condition as a controlled characteristic, not an optional finish.
Aerospace application
SIST EN 2942:2001 is written for aerospace applications. In practice, that means the standard is aimed at hardware used where traceability, defined material identity and consistent insert performance are important for aircraft and related equipment.
Temperature limit for testing
SIST EN 2942:2001 gives a maximum test temperature of 550°C. This is important because it sets the upper bound for test conditions associated with the insert, so test planning and qualification work should stay within that limit.
What terms does SIST EN 2942:2001 define?
The standard title uses several key terms that identify the product and its intended use.
- Self-locking - a feature that helps the insert resist loosening in service.
- Helical coil - a spiral, coil-shaped insert form used to create the threaded feature.
- Screw thread insert - a component fitted into a threaded hole to provide internal threads.
- Heat resisting nickel base alloy NI-PH2801 (Inconel X750) - the specified nickel-based alloy used for the insert body.
- Silver plated - coated with silver as the specified surface finish.
- Aerospace applications - use in aerospace hardware and assemblies.
- Maximum test temperature - the highest temperature stated for testing the insert.
Who uses SIST EN 2942:2001?
SIST EN 2942:2001 is used by people who specify, buy, inspect or certify aerospace threaded inserts. That typically includes design engineers, procurement teams, quality managers, incoming inspectors and suppliers working with aerospace fasteners.
It is especially useful when a buyer needs to state the exact insert type, material and finish in a purchase order, or when quality staff need a clear basis for checking that delivered parts match the required aerospace specification.
What changed in SIST EN 2942:2001 from the previous edition?
SIST EN 2942:2001 is the Slovenian standard identical to EN 2942:1998.
What does the SIST EN 2942:2001 document contain?
The published front matter identifies the standard in Slovenian, German, French and English, and it classifies the document under ICS 49.030.20. The rest of the standard is the product specification for the insert type named in the title.
For readers using it in practice, the document serves as the formal reference for the insert's defined characteristics, material designation, silver plated finish and temperature limit. It is the kind of standard used when a company needs a stable purchasing and inspection reference for an aerospace threaded insert rather than a general description of fasteners.
