Overview
EN ISO 2010:2011 - Slotted raised countersunk head screws (Product grade A) is the CEN-adopted version of ISO 2010:2011. This standard specifies the characteristics of countersunk slotted raised head screws of product grade A with metric threads from M1.6 to M10 inclusive. It replaces the earlier 1994 edition and is intended for manufacturers, designers and quality personnel working with small metric fasteners.
Key topics and requirements
- Scope and dimensions
- Defines thread sizes (M1.6 to M10), head geometry, shank and thread length relationships, and preferred nominal lengths.
- Includes dimensional tables and a figure showing head and shank features.
- Material and mechanical properties
- Covers typical property classes for steel (e.g., 4.8, 5.8) and corrosion-resistant stainless steel grades (A2-50, A2-70).
- Refers to ISO 898‑1, ISO 3506‑1 and ISO 8839 for mechanical property requirements.
- Threading and tolerances
- Specifies general-purpose metric thread standards (ISO 261, ISO 965‑2) and tolerance class 6g for external threads.
- Tolerance and product-grade requirements reference ISO 4759‑1.
- Surface integrity, coatings and finish
- Inspection and acceptance
- Acceptance inspection is specified by ISO 3269; designation examples (e.g., ISO 2010 - M5 × 20 - 4.8) are provided.
- Cross-references
Applications and who uses this standard
- Fastener manufacturers - design and production of slotted raised countersunk head screws to consistent dimensional, material and mechanical specifications.
- Product designers & engineers - selecting the correct head type and thread size (M1.6–M10) for assemblies in electronics, small machinery, appliance manufacturing, automotive trim, and precision equipment.
- Procurement and quality assurance - specifying product grade A fasteners, checking conformity, and applying acceptance inspection criteria.
- Standards committees and testing labs - reference for conformity assessment, test methods and interoperability of metric fasteners.
