Описание (английский):

This document specifies the characteristics of hexagon thin nuts (style 0), in steel and stainless steel, with metric coarse pitch thread M1,6 to M64, and with product grades A and B. Thin nuts used as jam nuts are to be assembled together with a regular or high nut. WARNING — Thin nuts (style 0) have a reduced loadability compared to regular nuts or high nuts, and are not designed to provide resistance to thread stripping (see ISO 898-2). If in certain cases other specifications are requested, stainless steel grades and property classes can be selected from ISO 3506-2.

Overview

ISO 4035:2023 - Fasteners - Hexagon thin nuts (style 0) defines the geometry, dimensions, marking and product requirements for hexagon thin nuts (style 0) made of steel and stainless steel with metric coarse pitch threads from M1.6 to M64. It covers product grades A and B, includes dimension tables (M5–M39) and a normative Annex A for sizes outside that range, and specifies labelling and designation practices. The standard warns that thin nuts have reduced loadability and are not intended to provide resistance to thread stripping.

Key topics and technical requirements

Scope: Hexagon thin nuts (style 0) in steel and stainless steel, thread sizes M1.6–M64, product grades A/B.

Dimensions: Main dimension tables for M5–M39; Annex A for D < M5 and D > M39. Symbols and dimension definitions follow ISO 225.

Threading and tolerances: Thread tolerance class 6H, thread form per ISO 965-1.

Product grades: Grade A for smaller sizes (e.g., D ≤ M16 in many cases) and Grade B for larger sizes; specific dimension notes (e.g., M5 d tolerance change).

Materials and properties: Steel and stainless steel grades referenced; stainless steel grades and property classes can be selected from ISO 3506-2 where applicable. For mechanical properties of carbon/alloy steel nuts, see ISO 898-2.

Surface condition and coatings: As-processed (uncoated) default; electroplated coatings per ISO 4042, zinc-flake ISO 10683, hot-dip galvanizing ISO 10684, plus passivation/clean-and-bright options.

Marking and labelling: Product marking follows ISO 898-2 (steel) or ISO 3506-2 (stainless steel); package labelling must include ISO 4035 reference, thread size, property class/grade, finish, manufacturer ID, lot number and quantity.

Use as jam nut: Thin nuts used as jam nuts must be assembled together with a regular or high nut.

Inspection and acceptance: Acceptance inspection per ISO 3269; surface discontinuities per ISO 6157-2.

Applications and users

ISO 4035:2023 is used by:

Fastener manufacturers for design and production of hexagon thin nuts

Mechanical designers and engineers specifying compact fastening solutions

Procurement and quality inspectors for conformity, marking and acceptance

Assemblers who use thin nuts as jam nuts or in space-restricted joints

Typical applications include assemblies where reduced nut height is needed (jam nut arrangements, confined spaces) while ensuring consistent thread fit and traceability.
