These standards from ISO and SAE cover Standardized Threading for Screws and Bolts requirements sorted by threading. This list covers general purpose screw standards.
This part of ISO 68 specifies the basic profile for ISO general purpose metric screw threads (M).
This part of ISO 68 specifies the basic profile for ISO inch screw threads.
Specifies the basic dimensions of metric threads in accordance with ISO 261. The basic dimensions are: basic major diameter of internal or external thread (nominal diameter), basic pitch diameter of internal or external thread, basic minor diameter of internal or external thread, height of fundamental triangle, pitch. The values refer to the basic profile in accordance with ISO 68.
Gives details for the manufacture and use of gauges for checking ISO general purpose metric screw threads. Specifies the features of gauges which are recommended for checking external and internal screw threads of workpieces. Provides means of distinguishing between threads that comply with the limits of size and those that do not.
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.
This International Standard specifies selected sizes for screws, bolts and nuts in the diameter range from 1 mm to 64 mm of ISO general purpose metric screw threads (M) having basic profile according to ISO 68-1. These selected sizes are recommended also for general engineering use. These screw threads are selected from ISO 261. For thread designations see ISO 965-1.
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 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: EI AZ = + (300 + 20P) where EI 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: EI AX = +(220P 20) where EI 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.
