Frequently Asked Questions

ICS 21.060 is a classification code in the International Classification for Standards (ICS) system. It covers "Fasteners". The ICS is a hierarchical classification system used to organize international, regional, and national standards, facilitating the search and identification of standards across different fields.

There are 2476 standards classified under ICS 21.060 (Fasteners). These standards are published by international and regional standardization bodies including ISO, IEC, CEN, CENELEC, and ETSI.

The International Classification for Standards (ICS) is a hierarchical classification system maintained by ISO to organize standards and related documents. It uses a three-level structure with field (2 digits), group (3 digits), and sub-group (2 digits) codes. The ICS helps users find standards by subject area and enables statistical analysis of standards development activities.

This document applies to arc stud welding of metallic materials subject to static and fatigue loading. This document specifies requirements that are particular to stud welding, in relation to welding knowledge, quality requirements, welding procedure specification, welding procedure qualification, qualification testing of operators and testing of production welds.
This document is applicable where it is necessary to demonstrate the capability of a manufacturer to produce welded construction of a specified quality.
NOTE            General quality requirements for fusion welding of metallic materials are given in ISO 3834-1, ISO 3834-2, ISO 3834-3, ISO 3834-4 and ISO 3834-5.
This document has been prepared in a comprehensive manner, with a view to it being used as a reference in contracts. The requirements contained within it can be adopted in full, or partially, if certain requirements are not relevant to a particular construction (see Annex A). For the working range of stud welding, see Annex B.

This document specifies the characteristics of prevailing torque hexagon high nuts (with non‑metallic insert), in steel and stainless steel, with metric coarse pitch thread M5 to M39, and with product grades A and B.
NOTE            These nuts are designed with an overall height equal to mmin (as specified in ISO 898-2 and ISO 4033 for style 2) plus the prevailing torque feature. The height of the prevailing torque feature (hmax – mmin) for the non-metallic insert is identical for regular, high and thin nuts for a given diameter.
If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-2 or ISO 3506-2.

Fasteners - Prevailing torque hexagon nuts - Thin nuts (with non-metallic insert)

This document specifies the characteristics of prevailing torque hexagon thin nuts (with non‑metallic insert), in steel and stainless steel, with metric coarse pitch thread M3 to M39, and with product grades A and B. NOTE These nuts are designed with an overall height equal to mmin (as specified in ISO 898-2 and ISO 4035 for style 0) plus the prevailing torque feature. The height of the prevailing torque feature (hmax – mmin) for the non-metallic insert is identical for regular, high and thin nuts for a given diameter. Nuts with sizes D WARNING - Thin nuts (style 0) have a reduced loadability compared to regular or high nuts, they 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.

Fasteners - Prevailing torque hexagon nuts - High nuts (all metal), with fine pitch thread

This document specifies the characteristics of prevailing torque (all metal) hexagon high nuts, in steel and stainless steel, with metric fine pitch thread 8 mm to 39 mm, and with product grades A and B. NOTE These nuts are designed with an overall height hmin = mmin (as specified in ISO 898-2 and ISO 8674 for style 2) plus the prevailing torque feature. hmax has been established in function of hmin; therefore, the tolerance (hmax – hmin) does not follow the ISO code system for tolerances (IT system). The wrenching height mw,min corresponds to the values specified for style 1. If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-2 or ISO 3506-2.

NOTE These nuts are designed with mmin as specified ISO 4032 and with an overall height h greater than in ISO 7042, in order to accommodate the prevailing torque feature with slot(s); this height h contributes to the nut resistance due to the number of engaged threads. hmin values have been calculated as a function of hmax together with a ratio hmax/D that progresses regularly with increasing diameter; therefore, the tolerance (hmax – hmin) does not follow the ISO code system for tolerances (IT system).
