1 SCOPE This Standard provides performance and safety requirements for hexagonal shank flat tip and Phillips (PH) 1 and Pozidriv (PZ) design screwdriver bits intended for manual (nonpower) operation in driving or removing screws with slotted heads and screws with Phillips or Pozidriv recesses. The screwdriver bits are ofthe types normallyusedbycabinetmakers, carpenters, sheet metal workers, production workers, mechanics, etc. Inclusion of dimensional data in this Standard is not intended to imply that all of the products described herein are stock production sizes. Consumers are requested to consult with manufacturers concerning the list of stock production sizes. 2 CLASSIFICATION Screwdriver bits, hand driven, hexagonal shank are classified in the following three types: (a) Type I — flat tip (see Fig. 1) (b) Type II — cross tip (PH) (see Fig. 2) (c) Type III — cross tip (PZ) (see Fig. 3) 3 REFERENCES The following is a list of publications referenced in this Standard.

4 PERFORMANCE REQUIREMENTS The illustrations herein are descriptive, not restrictive, and shall not preclude designs (such as double-ended bits) otherwise in accordance with the requirements of the Standard. 4.1 Design Screwdriver bits shall pass applicable tests in section 5. Conformance with marking and other requirements not determined by a test shall be verified by visual examination. 4.1.1 Type I. Dimensions for bits shall conform to Table 1 (see Figs. 1 and 4). 4.1.2 Type II. Bits shall be designed for driving or removing screws with PH recesses. They shall conform to the dimensional and performance characteristics specified in Figs. 2 and 4 and Tables 2 and 3. Tip dimen- sions shall be gaged in accordance with ASME B107.31M. 4.1.3 Type III. Bits shall be designed for driving or removing screws with PZ recesses. They shall conform to the dimensional and performance characteristics specified in Figs. 3 and 4 and Tables 4 and 5. Tip dimen- sions shall be gaged in accordance with ASME B107.31. 4.1.4 Retention Grooves. Retention grooves are optional. The locations and configurations of retention grooves are shown in Fig. 4. 4.2 Materials The materials used in the manufacture of screwdriver bits shall be such as to produce bits conforming to this Standard. 4.3 Marking Each bit shall be marked in a plain and permanent manner with the manufacturer’s name or a trademark of such known character that the manufacturer shall be readily determined. The marking shall be as permanent as the normal life expectancy of the bit 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 procedures normally expe- rienced during its intended use.
5.2 Materials The materials used in the manufacture of a screw- driver shall be such as to produce products conforming to the performance requirements specified herein. 5.3 Markings Screwdrivers shall be marked in a plain and perma- nent manner with the manufacturer’s name or a trade- mark of such known character that the manufacturer shall be readily determined. Marking shall be as perma- nent as the normal life expectancy of the screwdriver 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 procedures nor- mally experienced during its intended use. 5.4 Blade 5.4.1 GeneralRequirements. The blade shall be held securely in the handle. The blade shall be essentially free fromscale, seams, laps, and cracks, which mayadversely affect durability or serviceability of the tool. 5.4.2 Finish. The blade shall be treated in a manner to resist rust or corrosion. There shall be no evidence of peeling or chipping of any coating where applicable. 5.4.3 Hardness. The tip portion of the screwdriver or the entire blade shall be hardened to not less than 48 HRC (see para. 6.1).
