SIST EN 2889:2009 is the Slovenian adoption of EN 2889:2006 for aerospace metric bolts with a normal hexagon head, coarse tolerance normal shank, short thread, in alloy steel, cadmium plated. It specifies the bolt characteristics, how the bolts are identified and marked, and the technical basis for making and inspecting them. The standard is for aerospace design, procurement, manufacturing and quality teams that need a defined fastener type with a stated 900 MPa / 235 °C classification.

What does SIST EN 2889:2009 specify?

SIST EN 2889:2009 specifies the characteristics of these bolts and organizes them as a product standard rather than a general fastener handbook. In practice, that means a buyer or engineer can use one document to define the bolt family, the permitted options, and the related marking and quality rules.

The document is arranged in six clauses: Scope, Normative references, Required characteristics, Designation, Marking, and Technical specification. Figure 1 and Tables 1 to 3 carry the product-specific details that support ordering, checking and identification.

What are the key requirements of SIST EN 2889:2009?

SIST EN 2889:2009 ties the bolt definition to geometry, material, coating, designation and acceptance-related rules. The most important points are the ones that affect interchangeability, corrosion protection, and how the bolt is ordered and inspected.

Geometry and dimensions

Clause 3 says the configuration, dimensions and masses are given in Figure 1 and Table 1. Dimensions and tolerances follow ISO 3193 and apply after surface treatment, while form and position tolerances follow ISO 7913.

In practice, this means the finished, coated part is the reference for dimensional control. Manufacturers cannot rely only on pre-coating size; the final bolt has to fit the aerospace interface after plating.

Material and classification

Clause 3.3 assigns the material basis through TR 3775 as alloy steel in strength class 900 MPa. The title and scope also classify the bolt for 900 MPa at ambient temperature and 235 °C.

In practice, this tells the user the expected strength class and the temperature-related limit linked to the surface condition. It is the starting point for design selection and procurement matching.

Surface treatment

Clause 3.4 requires cadmium plating to EN 2133. The plating is defined for all surfaces that can be contacted by a 20 mm diameter ball, and the rest of the surface must also have continuous cadmium coverage.

In practice, this matters for corrosion protection and for checking whether the coating reaches all accessible areas. The clause also allows a black colour option identified by code B.

Designation

Clause 4 gives the designation structure using a description block and an identity block. The example shows how the standard number, hole code, diameter code, length code and colour code are combined.

In practice, this is what purchasers and planners use on drawings, purchase orders and stock records. If needed, code I9005 is inserted between the blocks.

Marking

Clause 5 requires marking according to EN 2424 and Figure 1, with the style linked to Table 3. The diameter code determines the marking style.

In practice, this helps trace the bolt after supply and during incoming inspection. It links the physical marking to the ordered size.

Technical specification

Clause 6 bases the technical specification on ISO 7689 and then modifies it. It adds manufacturer approval through EN 9100, changes the hardness requirement at the thread end, replaces the defect classification limit, and deletes several requirements including qualification of bolts, cold rolling, tension fatigue strength, tensile strength and head-to-shank fillet work effect.

In practice, this clause is the quality-control core of the standard. It tells manufacturers what approval system to work under and what technical checks the bolt has to satisfy.

What terms does SIST EN 2889:2009 define?

• Description block - The first part of the designation that names the product and the standard.
• Identity block - The code part that carries the hole, diameter, length and colour information.
• Hole code - The code that shows whether the bolt has no hole, a lockwire hole, a split pin hole, or both.
• Diameter code - The size code used in the designation and in the marking rules.
• Black colour code B - The option used when the black finish variant is required.
• MJ threads - The aerospace metric thread form used for the bolts.
• Lockwire - A securing option identified by the hole code.
• Split pin - Another securing option identified by the hole code.

Who uses SIST EN 2889:2009?

SIST EN 2889:2009 is used by aerospace designers, fastener manufacturers, plating suppliers, procurement teams and inspection staff. Designers use it to specify the right bolt form, buyers use it to order the correct coded product, and quality teams use it to verify material, coating, marking and technical compliance.

What changed in SIST EN 2889:2009 from the previous edition?

SIST EN 2889:2009 supersedes EN 2889:1995. The foreword states that the newer European Standard replaces the earlier edition.

Which standards are used with SIST EN 2889:2009?

Reference	What it contributes
ISO 3193	Dimensions for normal hexagonal head bolts with normal shank and short or medium length MJ threads
ISO 3353-1	Lead and runout threads for rolled external threads
ISO 5855-2	Limit dimensions for MJ threads on bolts and nuts
ISO 7689	Base procurement specification, modified by clause 6
ISO 7913	Tolerances of form and position
EN 2133	Cadmium plating requirement
EN 2424	Marking of aerospace products
EN 9100	Manufacturer approval through the aerospace quality management system
TR 3775	National materials basis for the alloy steel

What does the SIST EN 2889:2009 document contain?

SIST EN 2889:2009 contains one product configuration figure, three tables and six clauses. Figure 1 shows the bolt shape, optional holes and marking position. Table 1 gives the dimensional system, length coding and approximate masses, Table 2 gives the hole codes, and Table 3 links diameter code to marking style. Clause 6 is especially useful for manufacturing and inspection because it states the modified technical specification that sits behind acceptance and supply.
