adjusting worm: portion of the wrench used to adjust the clearance between the fixed and movable jaws. angle wrench: a wrench with one end having an angle over 55 deg. box wrench: wrench with an enclosed opening that grips all faces of the fastener. combination wrench: a wrench that is open on one end and box on the other. engineer’s wrench: in this Standard, a wrench that is open on one end, different size open on the other. NOTE: Industry may refer to single-ended open end wrenches as engineer’s wrenches. fixed jaw: portion of the frame that contacts the fastener. flare nut wrench: wrench that is used for gripping the nuts on the ends of tubes, with a slotted box end. frame: portion of the wrench containing the fixed jaw and handle. handle: portion of the wrench by which the tool is held. ignition wrench: a thin angle wrench. movable jaw: movable portion of an adjustable wrench that contacts the fastener. offset: pitch, or rotation around a transverse horizontal axis.
Type I wrenches shall be chamfered on both sides to provide a lead for the working surfaces. The slotted opening on Type I wrenches, and tips of all open ends on Type II wrenches, shall be chamfered or rounded to eliminate burrs. Internal drive end dimensions shall conform to ASME B107.4, except as noted in this paragraph. Two sides ofthe internal drive square shall be parallel to the line from the center of the internal drive opening to the center of the wrench opening within +3 deg. When the internal drive end is furnished with a hole or recess for engagement of the ball/ plunger on the corresponding external drive end, and the length of engagement of the external drive tang is less than twice the dimension of Din ASME B107.4, Table 8-1, the hole or recess shall be central in the corresponding internal drive. 5.3.1 Type I Flare Nut. Category 21, Type I wrenches shall have the flare nut design (see Figures 5.3.1-1 and 5.3.1-2]. The wrench shall have an internal drive opening at one end and a wrench opening to drive hexa- gonal fasteners. See Tables 5.3.1-1 through 5.3.1-4 (Table 5.3.1-4M). The slotted opening may be rotated from the centerline of the wrench.SCOPE This Standard provides performance and safety re- quirements for combination, open end, box, and flare nut wrenches; open end adjustable wrenches, with rack and worm adjustment, generally used on both hexa- gonal and square fasteners; crowfoot wrenches having a wrench component of the open end type or flare nut type; and ratcheting box wrenches used in hexagonal [6-point), double-hexagonal (12-point), square [4-point), and double-square (8-point) wrenching applications. The tools covered herein are listed by Category number in Table 4-1.
(b) Modified Single or Double Hexagon Box Configura- tion. This design consists of a geometric single hexagon (6- point) or double hexagon (12-point) configuration that does not contact on the fasteners’ corners. [c) Open-End Configuration. This design consists of a simple geometric configuration having an across-flats shape suitable for use on hexagonal and square- headed bolts and nuts. The tips of all open ends shall have no burrs. (d) Flare nut configuration. (e) Standard single or double square configuration, consisting of a single geometric square (4-point) or a double square [8-point) configuration having an across-flats and an across-corner shape for fitting with square fasteners. f Adjustable open-end configuration. Wrenches that have a box end design shall be chamfered on at least one side to provide a lead for the working surfaces. Wrench opening configurations in (a), (b], [d), and (e) shall be countersunk with an included angle of 90 deg to 150 deg and a minimum diameter equal to the across-corner dimension of the opening.
