Overview
SIST EN 4162:2026 is an aerospace series standard for a specific type of screw/bolt used in aircraft and related aerospace assemblies. It specifies the characteristics of 100° countersunk normal head screws with an offset cruciform recess, coarse tolerance normal shank, medium length thread, made from alloy steel and cadmium plated.
This standard is important for organizations that need reliable aerospace fasteners with defined dimensional, material, surface treatment, marking, and qualification requirements. It covers the product classification of 1 100 MPa at ambient temperature / 235 °C, supporting use in demanding aerospace environments where strength and consistency matter.
As an aerospace fastening standard, SIST EN 4162 helps ensure that screws are specified and procured in a controlled and interoperable way across the supply chain.
Key Topics
Product definition
- 100° countersunk normal head design
- Offset cruciform recess drive
- Coarse tolerance normal shank
- Medium length thread
- Alloy steel construction
- Cadmium plated surface treatment
Classification and performance
- Strength class: 1 100 MPa
- Temperature classification: 235 °C
- Intended for aerospace applications requiring standardized mechanical performance
Required characteristics
- Configuration, dimensions, and masses are defined in the standard
- Tolerances of form and position are referenced to applicable aerospace standards
- Materials and surface treatment requirements are specified for controlled production
Marking and designation
- Clear designation format supports procurement and traceability
- Marking is defined to help identify the product and its size code
Technical specification
- Manufacturer approval and qualification expectations are included
- Quality management and aerospace qualification procedures are referenced for compliance
Applications
SIST EN 4162:2026 is relevant wherever aerospace screws are used in structural or assembly applications that require standardized fastening performance. Typical practical uses include:
- Aircraft component assembly
- Aerospace maintenance and repair
- Procurement of standardized fasteners
- Manufacturing workflows that require controlled bolt and screw specifications
- Supply chain documentation for aerospace hardware
The standard supports engineers, buyers, quality teams, and manufacturers by providing a common reference for aerospace screw dimensions, cadmium-plated alloy steel fasteners, and consistent product identification.
