TEST METHODS:

The size, shank length, handle width and diameter of the wrenches were documented. The torque testing was conducted by placing the shank of the wrench into the matching size of a hex driver socket attached to a 2,000 in-lb torque transducer. The handle of the wrenches were rotated in the clockwise direction using a fixture (see drawing on page 6) designed to contact the handle with two (2), 3/8" diameters on opposite sides, at the span of; 2" for the 5/23" - 3/32" wrenches and 2-1/2" for the 1/4" - 3/16" wrenches. The wrenches were torqued until either the shank fractured (broke), spun loose in the handle or handle deformation caused loss of contact with the torque fixture. The indicated maximum peak torque and mode of break were documented for the wrenches.

TEST EQUIPMENT:

Lebow 2000.0 in-lb torque transducer, MTI# MM 120-002, calibrated traceable to the NIST on 2-3-98 due 2-3-00.

TEST METHODS:

The size, leg lengths and end styles of the wrenches purchased were documented. The torque testing was conducted by placing the shorter leg of the wrench 3/16" into the matching size of a hex driver socket. The hex socket was attached to a 2,000.0 in-lb torque transducer. To obtain the required leverage to stress the wrench, an extension arm (pipe) was placed over the longer leg to terminating 1 inch from 90° bend. The wrenches were then torqued clockwise until the wrench fractured (broke) off. The indicated maximum peak torque and location of break were documented for each wrench.

TEST EQUIPMENT:

Lebow 2K in-lb torque transducer, MTI# MM 120-002, calibrated traceable to the NIST on 2-3-98 due 2-3-00.

The strength of a Bondhus® hex key was tested against that of a competitor. The tools were inserted into the solid receptacle and then turned in opposite directions until one of the tools broke.

 

 

 

As test results below show, while the Bondhus® tool suffered no damage, the competitor's tool was twisted, deformed, and broken.
