REQUIREMENTS
The illustrations shown herein are descriptive andnot restrictive,and are not intended to preclude themanufacture of nutdrivers that are otherwise in accor-dance with this Standard.
4.1 Design
4.1.1 Type l,class 1: Conventional Length – SolidShaft. Type I, Class 1 nutdrivers shall consist of a roundsteel solid shaft with a socket at one end and a handleat the other end. The nutdrivers shall be similar to Fig.1and conform to Table 1 or 1M for the size specified.Style A nutdrivers shall be provided with a conventionalcolor-coded handle and / or shaft. Style B nutdriversshall be provided with a cushion grip handle and neednot be color-coded.
4.1.2 Type l,Class 2: Conventional Length – HollowShaft. Type I, Class 2 nutdrivers shall consist of a roundsteel hollow shaft with a socket at one end and a handleat the other end. The nutdrivers shall be similar to Fig.2and conform to Table 2 or 2M for the size specified.Style A nutdrivers shall be provided with a conventional color-coded handle and/or shaft. Style B nutdrivers shall be provided with a cushion grip handle and need not be color-coded.
4.1.3 Type II: Stubby Length. Type II nutdrivers shall consist of round steel shaft with socket at one end and a handle at the other end. A bolt clearance hole shall be provided in the shaft of the socket end. The nutdriver shall be similar to Fig. 3 and conform to Table 3 or 3M for the size specified. Style A nutdrivers shall be provided with a conventional color-coded handle and/ or shaft. Style B nutdrivers shall be provided with a cushion grip handle and need not be color-coded.
4.1.4 Type III: Miniature Handle. Type III nutdrivers shall consist of a round steel shaft with a socket at one end and a handle at the other end. A bolt clearance hole shall be provided in the shaft socket end. The nutdriver shall be similar to Fig. 4 and conform to the Table 4 or 4M for the size specified. Handle and/or shaft shall be color-coded.
4.2 Materials The materials used in the manufacture of nutdrivers shall be such as to produce tools conforming to the requirements specified herein.
4.3 Marking Nutdrivers shall be marked in a plain and permanent manner with manufacturer’s name or with a trademark of such known character that the manufacturer shall be readily determined. Marking shall include the product number and nominal socket opening size. Marking shall be as permanent as the normal life expectancy of the nutdriver to which it is applied (providing the marked surface has not been subjected to a fretting or abrading action) and be capable of withstanding the cleaning pro- cedures normally experienced during its intended use.
