ASME B107.100 pdf download.Flat Wrenches.
ASME B107.100 provides performance and safety requirements for combination, open end, box, and flare nut wrenches; open end adjustable wrenches, with rack and worm adjustment, generally used on both hexagonal 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.
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 make sizes not listed in this Standard. Consumers are requested to consult with manufacturers concerning lists of stock production sizes.
2 DEFINITIONS
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.
engineers 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.
1710 vable jaw: movable portion of an adjustable wrench that contacts the fastener.
offset: pitch, or rotation around a transverse horizontal axis.
6.7 Drop Test — Categories 8 and 66
The wrench shall be dropped from a height of 6 ft onto a concrete surface 12 times. For Category 8, the movable jaw shall be at least halfway open when dropped. After this test, all component parts shall remain properly assembled. and the movable jaw and adjustment mechanism shall work satisfactorily. For Category 66. on wrenches with protruding shifters, the tester should attempt to have the shifter strike first on the concrete at least twice during the test. There shall be no physical failure of any component, and the wrench must be fully functional after this test.
6.8 Reversing Torque — Category 66
Category 66, Type II wrenches shall be tested for reversing torque after they have been tested for proof torque. Each wrench shall be rotated 360 deg after the proof load test and before measuring reversing torque. The reversing torque shall not exceed the requirements in Table 6.2.3-1 (Table 6.2.3-IM).
6.9 Cycle Test — Category 66
The applied torque for cycle testing shall be 35% of the proof torque specified in Table 6.23-1 (Table 6.2.3-1M). Samples shall be tested at a rate not to exceed 60 cycles/ mm. The ratcheting gear mechanism shall withstand a cycle test of 5,000 cycles in the clockwise direction and 5,000 cycles In the counterclockwise direction.
