This International Standard specifies ISO general purpose metric screw threads (M) having basic profile according to ISO 68-1. Basic dimensions are given in ISO 724. For tolerances see ISO 965-1.
Specifies the widths to be used in the respective product standards; it sets out a logical ratio between underhead (or nut) bearing area and the tensile stress area of the screw thread.
This International Standard specifies the characteristics of\nshort-pitch precision roller and bush chains with associated\nsprockets suitable for the mechanical transmission of power and\nallied applications. It covers dimensions, tolerances, length\nmeasurement, preloading, minimum tensile strengths and minimum\ndynamic strength.\nAlthough Clause 5 applies to chain sprockets for cycles and\nmotor cycles, this International Standard is not applicable to\ntheir chains, which are covered by ISO 9633 and ISO 10190,\nrespectively.
Includes tolerances on leg length, on thickness, cutting tolerance for length, tolerances on mass, straightness and out-of-square.
This International Standard specifies tolerances on wrench and socket openings for screws and nuts (or similar parts) having metric width across flats dimensions, as shown diagrammatically below.It gives, for each dimension, the tolerances for general use, defined by its two deviations, minimum and maximum, with respect to the nominal value.These deviations have been determined in relation to the width across flats tolerances for screws and nuts specified in ISO 4759-1 and with regard to the manufacture of tightening tools.
Specifies the dimensions for seven nominal sizes. This third edition cancels and replaces the second edition (1985), which has been technically revised (addition of round drill steels and extension of the range of sizes).
Specifies the dimensions of both forged collared shanks and corresponding chuck bushings. Values are given for five nominal sizes. This second edition cancels and replaces the first edition (1974), which has been technically revised (extension of the range of sizes and specification of the size of the internal diameter at the forged collar).
This part of ISO 727 specifies the dimensions of plain sockets (cylindrical and conical) in fittings made from unplasticized polyvinyl chloride) (PVC-U), chlorinated polyvinyl chloride) (PVC-C) oracrylonitrile/butadiene/styrene (ABS), intended for connecting by solvent cementing to pipes of the corresponding material for use under pressure. 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.
This International Standard specifies the sizes of the radii under the head and the transition diameters of metric series general purpose bolts and screws.
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.
This standard is about Plain washers for metric bolts, screws and nuts for general purposes - General plan; Technical Corrigendum 1
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.
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.
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.
This document specifies limit deviations and limits of sizes for the pitch and crest diameters of the hot-dip galvanized metric external screw threads conforming to the coarse thread series of ISO 262 (from M8 to M64) having a basic profile according to ISO 68-1. This document is applicable to the hot-dip galvanized metric external screw threads to mate with the internal screw threads tapped with tolerance position H or G after galvanizing.
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.
\"Internal threads shall be tapped after the hot-dip galvanizing process has been completed, therefore no galvanizing coating is present on the surface of internal threads.\"
This document specifies the size pairing of double-ended wrenches with unequal nominal widths across flats. NOTE The wrenches covered by this document are those identified in ISO 1703:2005 under reference nos. 1 1 01 02 0, 1 1 02 03 0, 1 1 02 04 0, 1 1 02 05 0, 1 1 02 06 0, 1 1 02 08 0.
