Overview
ISO 7436:2024 is an international standard that specifies the characteristics of slotted set screws with cup point made from steel and stainless steel. These fasteners feature metric coarse pitch threads ranging from M1.6 to M12, and conform to product grade A. This second edition updates and replaces the original ISO 7436:1983, incorporating important revisions regarding thread lengths, material grades, hardness classes, surface treatments, marking, and labelling.
Designed to standardize dimensions, mechanical properties, and surface conditions, ISO 7436:2024 ensures consistent quality and performance in slotted set screws with cup point. It also references additional standards for complementary requirements related to hardness, stainless steel grades, tolerances, coatings, and inspection.
Key Topics
Dimensions and Tolerances
Specifies precise dimensions for threads, points, lengths, and chamfers in accordance with ISO 225, ISO 724, ISO 888, ISO 965-1, and ISO 4753. It defines nominal and permissible limits for pitch, minor diameter, thread length, and head angles (90° or 120°).Material and Hardness Classes
Covers steel and stainless steel grades with mechanical properties defined by ISO 898-5 and ISO 3506-3. Includes hardness classes for steel fasteners (e.g., 14H, 22H) and stainless steels such as A1, A2, and A4 with specified hardness classes (12H, 21H).Surface Condition and Coatings
Details on surface finishes including "as processed" for steel, "clean and bright" or "passivated" for stainless steel, and options for electroplated or non-electrolytically applied coatings per ISO 4042 and ISO 10683. It also sets requirements for surface integrity referencing ISO 6157-1.Marking and Labelling
Marking on individual screws is optional unless agreed upon. Package labelling must include standard reference, thread size, nominal length, hardness class or stainless steel grade, surface finish, manufacturer identification, lot number, and quantity, ensuring traceability and conformity.Designation System
Follows ISO 8991 guidelines to denote thread size, length, product grade, and material hardness or grade. Examples:- Steel: Set screw ISO 7436 – M5 × 12 – 14H
- Stainless steel: Set screw ISO 7436 – M5 × 12 – A2-12H
Applications
Slotted set screws with cup point as specified in ISO 7436:2024 are widely used across various industries, including:
Mechanical Engineering
For securing components where precise axial positioning is needed without protrusions, such as locking parts on shafts.Automotive and Aerospace
Providing reliable fastening solutions in assemblies that demand high strength and corrosion resistance.Electronics and Electrical Engineering
Used for grounding and fastening in devices where conductive stainless steel fasteners are required.General Manufacturing and Maintenance
Serves as a standardized fastener choice facilitating interchangeability, inventory management, and quality assurance.
Adhering to ISO 7436:2024 enhances product reliability, reduces manufacturing errors, and simplifies procurement processes by defining uniform specifications and quality controls.
Related Standards
ISO 7436:2024 references and aligns with multiple international standards to ensure comprehensive technical coverage, including:
- ISO 898-5: Mechanical properties of steel fasteners for set screws and similar items with specified hardness classes.
- ISO 3506-3: Mechanical properties for corrosion-resistant stainless steel set screws.
- ISO 888: Nominal lengths and thread lengths for bolts and screws.
- ISO 965-1: Tolerances for general purpose metric screw threads.
- ISO 4759-1: Tolerances for fasteners covering product grades.
- ISO 4042: Electroplated coating systems for fasteners.
- ISO 10683: Non-electrolytically applied zinc flake coatings.
- ISO 6157-1: Surface discontinuity requirements for bolts and screws.
- ISO 3269: Acceptance inspection methods.
- ISO 225: Symbols and descriptions of fastener dimensions.
- ISO 8991/8992: Designation and general requirements for fasteners.
These standards complement ISO 7436 by detailing material characteristics, quality verification, surface treatments, and thread tolerance systems essential for reliable fastener performance.
By following ISO 7436:2024, manufacturers and engineers ensure consistent product quality and interoperability for slotted set screws with cup point, streamlining production and enhancing durability across industrial applications.

nom
— for stainless steel screw, grades A2 and A4 with hardness classes 12H and 21H have been added;
— non-ferrous metal screws have been deleted (as a consequence of the withdrawal of ISO 8839);
— for steel fasteners, “plain” has been changed to “as processed” in Table 3;
— for stainless steel fasteners, “plain” has been changed to “Clean and bright”, and “Passivated” has been
added in Table 3;
— the requirement of surface integrity has been added for steel screws in Table 3;
— specifications for marking and labelling have been added as Clause 6.
