ASME B107.110-2019 pdf download.Socket Wrenches, Handles, and Attachments.
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. 2 REFERENCES The following is a list ofpublications referenced in 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.UniversalJointSockets(Category1, Category2, and Category34). Universaljointsockets shall consistofa single- (6-point) ordouble-hexagon(12-point) socketand an internal drive end. Each member shall be permanently attached to each other or by means of an intermediate member to form a universal joint. The sockets shall be provided with a means to hold the drive end and socket end in any set position with a force adequate to hold the socket against gravity. For universal sockets with square block joints, angular deviation from the centerline is 40 deg minimum. For universal sockets with ball-swivel joints, angular deviation from the center- line is 20 deg minimum to 35 deg maximum. Ifhinge pins areused,theyshallnotextendbeyondtheperipheryofthe universal joint section by more than 0.031 in. (0.79 mm) and shall not interfere with the regular operation of the universal joint. The portion of the hinge pin that extends beyond the periphery shall not have sharp edges.
