Overview
EN ISO 1482:2011 (ISO 1482:2011) is the international/CEN standard that specifies the characteristics of slotted countersunk (flat) head tapping screws. It covers thread sizes from ST 2,2 to ST 9,5 inclusive and defines dimensional, material and conformity requirements for these commonly used fasteners. The standard was approved in 2011 and supersedes earlier editions.
Key topics and technical requirements
- Scope and dimensions
- Defines geometry for slotted countersunk (flat) head tapping screws (Types C, F and R) and provides detailed dimensional data (see Table 1 for pitch, head diameter, head height, slot dimensions and preferred lengths).
- References ISO 225 for symbols and dimension descriptions.
- Materials and mechanical properties
- Steel tapping screws: specified in accordance with ISO 2702 (heat-treated steel tapping screws - mechanical properties).
- Stainless steel grades: A2-20H, A4-20H, A5-20H in accordance with ISO 3506-4.
- Mechanical hardness class and product grade A are indicated for applicable materials.
- Threads and head configuration
- Thread form: ISO 1478 (tapping screws thread).
- Countersunk head configuration and gauging: ISO 7721.
- Finish, coatings and corrosion protection
- Electroplated coatings: ISO 4042.
- Non-electrolytically applied zinc flake coatings: ISO 10683.
- Passivation for stainless steel: ISO 16048.
- Tolerances, acceptability and inspection
- Dimensional tolerances: ISO 4759-1.
- General fastener requirements: ISO 8992.
- Acceptance inspection procedures: ISO 3269.
- Designation examples
- Tapping screw ISO 1482 - ST 3,5 × 16 - St - R (steel, rounded end)
- Tapping screw ISO 1482 - ST 3,5 × 16 - A4-20H - R (stainless steel A4-20H, rounded end)
Applications and who uses this standard
- Manufacturers of tapping screws and fasteners use EN ISO 1482 to design, produce and mark slotted countersunk head tapping screws to internationally recognised dimensions and material classes.
- OEMs and procurement engineers in industries such as electronics, appliances, automotive, construction and furniture use the standard to specify compliant fasteners and ensure interchangeability.
- Quality and inspection teams apply the referenced acceptance and tolerance standards to verify product conformity and supplier performance.
- Design and maintenance engineers rely on standard dimensions and designation rules to select the correct countersunk tapping screw for assembly, fastening in sheet metal and repair tasks.

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
