The resulting joint does not require mechanical anchorage.NOTE It is strongly recommended that the advice of the fittings manufacturer be sought in the selection of an appropriate type of solvent cement, depending upon whether the cylindrical or conical type of socketed fitting is being used for a particular installation.

ISO 885-2000普通螺栓和螺钉 米制系列 头下圆角半径

This International Standard specifies the sizes of the radii under the head and the transition diameters of metric series general purpose bolts and screws.

ISO 887-2000米制普通螺栓、螺钉和螺母用平垫圈 总方案

This International Standard specifies the full range of the nominal dimensions of product-grade-A and -C plain washers for general-purpose bolts, screws and nuts of nominal thread diameters ranging from 1 mm to 150 mm inclusive.This International Standard is not applicable to washers for screw and washer assemblies in relation to hole diameters and thicknesses.Information on the use of plain washers is given in annex A.

ISO 887 CORR 1-2006通用米制螺栓、螺钉和螺母用普通垫圈.一般示意图.技术勘误1

This standard is about Plain washers for metric bolts, screws and nuts for general purposes - General plan; Technical Corrigendum 1

ISO 965-1-2013ISO通用米制螺纹. 公差. 第1部分: 原则和基本数据

This part of ISO 965 specifies a tolerance system for ISO general purpose metric screw threads (M) according to ISO 261.The tolerance system refers to the basic profile according to ISO 68-1.

ISO 965-2-1998ISO一般用途米制螺纹. 公差. 第2部分: 一般用途内螺纹和外螺纹的极限尺寸. 中等质量

This part of ISO 965 specifies limits of sizes for pitch and crest diameters for ISO general purpose metric screw threads (M) conforming to ISO 262 having basic profile according to ISO 68-1.The limits of sizes for the tolerance quality specified are derived from the fundamental deviations and tolerances specified in ISO 965-1.

ISO 965-3-2021ISO一般用途米制螺纹. 公差. 第3部分: 螺纹的极限偏差

This document specifies limit deviations for pitch and crest diameters for ISO general purpose metric screw threads (M) conforming to ISO 261 having basic profile in accordance with ISO 68-1. The limit deviations specified are derived from the fundamental deviations and tolerances specified in ISO 965-1. This document is applicable to ISO general purpose metric screw threads with the recommended tolerance classes.

ISO 965-4-2021ISO一般用途米制螺纹. 公差. 第4部分: 热浸镀锌外螺纹的极限尺寸、与其相配的内螺纹镀锌后攻丝、内螺纹的公差带位置为H或G

ISO 965-5-1998ISO一般用途米制螺纹. 公差. 第5部分: 与镀锌前公差带位置为h大尺寸的热沉镀锌外螺纹相配的内螺纹的极限尺寸

This part of ISO 965 specifies deviations and limits of sizes for pitch and crest diameters for ISO general purpose metric internal screw threads conforming to ISO 262 having basic profile according to ISO 68-1.Internal screw threads according to this part of ISO 965 are intended to mate with external screw threads with maximum size of tolerance position h before hot-dip galvanizing.The limits of sizes for the tolerance quality specified are derived from tolerances specified in ISO 965-1.The fundamental deviations for internal screw threads with a tolerance position AZ have been calculated according to the following formula:ElAZ = + (300 + 20P)whereEI is expressed in micrometres;P is expressed in millimetres.The fundamental deviations for internal screw threads with a tolerance position AX have been calculated according to the following formula:ElAX = + {220P - 20)whereEI is expressed in micrometres;P is expressed in millimetres.Products made with thread tolerances according to this part of ISO 965 may show load failure when tested in accordance with ISO 898-2 without adjustment of the other mechanical properties.Internal screw threads with thread tolerances according to this part of ISO 965 must not be mated with external screw threads having thread tolerances according to ISO 965-4 because such combinations will create severe risk of thread stripping.NOTE Internal screw threads with tolerance class 6AZ are primarily intended to mate with external screw threads centrifuged after hot-dip galvanizing.Internal screw threads with tolerance class 6AX are primarily intended to mate with hot-dip galvanized external screw threads with heavy coating not centrifuged.
