ASME B107.110:2019 pdf download.Socket Wrenches, Handles, and Attachments
1 SCOPE
This Standard provides performance and safety re- quirements for socket wrenches (sockets), handles used with these wrenches, nutdrivers, and attachments used with socket wrenches, hereinafter collectively referred to as tools. The tools covered in this Standard are listed by Category number in Table 3-1. The names and intended uses given in Table 3-1 are those generally recognized. Inclusion of dimensional data in this Standard is not intended to imply that all of the products described herein are stock production sizes. Manufacturers may produce sizes not listed in this Standard. Consumers are requested to consult with manufacturers concerning lists of stock production sizes and lengths.
4 PERFORMANCE REQUIREMENTS
The illustrations shown herein are descriptive and not restrictive, and are notintended to preclude the manufac- ture of tools that are otherwise in accordance with this Standard. Dimensions shall be in accordance with the ap- plicable tables unless otherwise specified. Lengths in U.S. Customary tables are in inches; lengths in SI tables are in millimeters. Tools shall pass all applicable tests in section 5 and meet category requirements as applicable. 4.1 Design 4.1.1 Nut End Socket Opening. The internal wrench opening of a single-hexagon (6-point) or a double- hexagon (12-point) configuration, or a single-square (4-point) or a double-square (8-point) configuration shall conform to one of the following wrench opening designs. (a) Standard Single- or Double-Hexagon Configuration. This design consists ofa simple geometric single-hexagon (6-point) or a double-hexagon (12-point) configuration having an across-flats and an across-corner shape for fitting with commercial hexagon fasteners. (b) Modified Single- or Double-Hexagon Configuration. This design consists of a geometric single-hexagon (6- point) or a double-hexagon (12-point) configuration that does not contact on the fastener’s corners. (c) Standard Single- or Double-Square Configuration. This design consists of a simple geometric single- square (4-point) or a double-square (8-point) configuration having an across-flats and an across-corner shape for fitting with commercial square fasteners. The across-flats and across-corners tolerances of all wrench opening designs shall be as such to ensure accep- tance when measured with gages conforming to ASME B107.17. 4.1.2 BoltClearanceHoleforCategory1andCategory 2 Sockets. A space shall be provided for bolt clearance in all sockets except for Category 1 and Category 2, Type III universal joint sockets (Figure 3-2). The diameter of the bolt clearance hole shall be in accordance with that ofthe applicable size socketas specified in the applicable tables. The minimum depth for the bolt clearance hole, as measured from the nut end face, shall be 1.5 times the minimum opening depth, nut end for sockets with overall length less than the following:or a minimum bolt clearance hole depth of 50% of the overall length for sockets with overall length equal to or greater than the length values listed above. For Category 2, Type III universal joint sockets (Figure 3-2), all 3 ∕ 8 in. drive universal sockets with overall length greater than 2.750 in. shall have minimum bolt clearance depth of 0.937 in., and all 1 ∕ 2 in. drive universal sockets with overall length greater than 3.500 in. shall have minimum bolt clearance depth of 1.250 in. 4.1.3 Drive Ends. Drive ends, when provided, shall conform to ASME B107.4. 4.1.4 CountersinkofNutEnd SocketOpening. Thenut end socketopeningshall be countersunkwith an included angle of90 degto 150 deg(forCategory34, the angle shall be 85 deg to 155 deg) and a minimum diameter equal to the across-corners dimension of the opening.
