Assembly Tools for Screws and Nuts

Assembly tools for screws and nuts provide a remarkably simple and immediately apparent need for standardization-the shapes of all the tools have to fit the shapes of the screws and nuts. ISO standards address the different combinations of tips and bits that arise, and specify minimum values, dimensions, designations, and markings that guide those working with the tools. Additionally, test methods and conditions are provided, assuring uniformity and reliability in production.

Assembly tools for screws and nuts -- Drive ends for hand- and machine-operated screwdriver bits and connecting parts -- Dimensions, torque testing

This International Standard specifies the dimensions and torque testing of drive ends for hand- and machine-operated screwdriver bits as well as to driving spindles of screw driving machines. It ensures the interchangeability of tool bits and tool holders. This International Standard defines only the distinctive features of individual drive ends. Details of design, e.g. of fixing devices, are left to the user of this International Standard.


ANSI B11.6-2001 (R2020)

Safety Requirements for Manual Turning Machines with or without Auto Control

This standard specifies safety requirements for the design, construction, operation and maintenance (including installation, dismantling, and transport) of the general class of manually controlled horizontal and vertical spindle turning machines. Machines covered by this standard are intended to work metals and other man–made materials. This standard also applies to devices that are integral to the machine. These machines may have automatic capability but may not be equipped with automatic part handling or bar–feed mechanisms nor automatic tool changing systems.
