ASME B107.600-2008 pdf download.Screwdrivers.
1 SCOPE This Standard covers straight handle-type screwdriv- ers of flat tip design intended for manual operation in driving or removing screws with slotted recesses. The screwdrivers are of the types normally used by cabinet- makers, carpenters, sheet metal workers, production workers, mechanics, etc. The intention is to specify per- formance rather than design detail. Inclusion of dimensional data in the Standard is not intended to imply that all of the products described herein are stock production sizes. Consumers are requested toconsultwithmanufacturers concerninglists of stock production sizes. Using a screwdriver as a pry bar or striking it with a hammer are clearly misuses of the tool, and nothing in this Standard shall be interpreted as condoning any tool misuse. Further information about proper use of screw- drivers is contained in the Guide to Hand Tools — Selection, Safety Tips, Proper Use and Care. 2 CLASSIFICATION Flat tip screwdrivers are classified in the following two types: (a) Type I — cabinet, straight sides (b) Type II — general purpose, flared sides 3 DEFINITIONS assembly: the blade plus the handle. blade: the shank plus the tip. bolster: a change in the geometry of the shank at the junction of the handle. handle: that portion of the screwdriver that is gripped with the hand. shank: the portion of the blade between the tip and the handle. tip: the portionofthe blade thatengages thescrew recess. See Fig. 1 for more information. 4 REFERENCES The following is a list of publications referenced in this Standard. ASTM D 2240, Standard Test Method for Rubber Property — Durometer Hardness

Conformance with marking and other requirements not determined by a test shall be verified by visual examina- tion. Screwdrivers shall conform to the dimensional and performance characteristics specified in Tables 1 and 2. Screwdrivers may be supplied with a bolster. 5.1.1 Type I. Flat tip, straight-sided cabinet screw- drivers are for driving and removing slotted screws (see Fig. 2). The entire length of the blade, excluding the bolster if one is present, shall be capable of entering a round hole no larger than the maximum allowable tip width dimension plus 0.031 in.
5.1.2 Type II. Flat tip, flared-sided general purpose screwdrivers are for driving and removing slotted screws (see Fig. 2). 5.2 Materials The materials used in the manufacture of a screw- driver shall be such as to produce products conforming to the requirements of this Standard. 5.3 Markings Screwdrivers shall be marked in a plain and perma- nent manner with the manufacturer’s name or with a trademark of such known character that the manufac- turer shall be readily determined. Marking shall be as permanent as the normal life expectancy of the screw- driver to which it is applied (providing the marked sur- face 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. 5.4 Blade 5.4.1 GeneralRequirements. The blade shallbe held securely in the handle and essentially free from scale, seams, laps, and cracks, which may adversely 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 screwdrivers or the entire blade shall be hardened to not less than 48 HRC (see para. 6.2).
