Overview

EN ISO 8674:2023 - titled "Fasteners - Hexagon high nuts (style 2), with fine pitch thread (ISO 8674:2023)" - is the CEN-endorsed European adoption of the ISO standard that specifies the characteristics of hexagon high nuts (style 2) in steel and stainless steel. It covers metric fine pitch threads from 8 mm to 39 mm and defines product grades A and B. The standard sets dimensional, material and marking/labeling requirements to ensure interchangeability, quality and traceability of fasteners.

Key topics and technical requirements

Scope & sizes: Nuts with metric fine-pitch threads D × P in the range M8 to M39 (fine pitch variants included). Dimensions and tolerances are given in figures and tables; nuts are supplied normally without washer-face unless specified.

Materials & property classes: Applies to steel and stainless steel nuts. Property classes and stainless grades can be chosen per ISO 898-2 (steel) or ISO 3506-2 (stainless steel). Common property classes for nuts include 8, 10 and 12 depending on diameter ranges.

Mechanical treatment: Specifies quenching and tempering requirements in accordance with ISO 898-2 for steel (QT or NQT as applicable). Stainless steel mechanical grades reference ISO 3506 series.

Threads & tolerances: Thread tolerance class 6H and references to ISO 965-1 for general purpose metric thread tolerances.

Surface condition & coatings: As-processed (uncoated) delivery by default; electroplated coatings per ISO 4042 or non‑electrolytically applied zinc‑flake per ISO 10683. Surface discontinuity limits reference ISO 6157-2.

Inspection & acceptance: Acceptance inspection requirements per ISO 3269; tolerances per ISO 4759-1 (product grades A, B, C).

Marking & labelling: Product marking follows ISO 898-2 (steel) or ISO 3506-2 (stainless). Package labeling must include ISO 8674 reference, thread size D×P, property class/grade, finish, manufacturer ID, lot number and quantity.

Applications and who uses this standard

Manufacturers and suppliers of hexagon nuts and fasteners for consistent production and international trade.

Design and mechanical engineers specifying fine‑pitch hexagon high nuts for machinery, automotive, construction, and equipment requiring precise thread engagement.

Procurement, quality and inspection teams ensuring incoming nuts meet dimensional, mechanical and marking requirements for assembly and safety-critical applications.

Standards and compliance officers using EN ISO 8674:2023 to harmonize product specifications across European and international markets.

Example designation (from the standard):

Hexagon high nut ISO 8674 – M24×2 – 10

Related standards
