a nut configured to be selectively retained at a plurality of positions along the bolt body corresponding with one or more of the plurality of engagement elements;

a base configured to secure the nut to the fixture such that movement of the nut between the plurality of positions correspondingly adjusts mounting of the bolt relative to the fixture and in turn the object supported on the tine, thereby adjustably mounting the object to the fixture;

wherein the plurality of engagement elements are spaced apart along an axial length of the bolt body, the axial length being greater than a width of the nut such that the nut can be positioned at a middle position and moved therefrom toward at least a forward position and a rearward position, each of the middle, forward and rearward positions being a corresponding one of the plurality of positions; and

wherein the base is immovable affixed to the nut such that an offset measured along the axial length of the bolt body between the tine and the fixture increases when the nut moves from the middle position toward the forward position and decreases when the nut moves from the middle position toward the rearward position.

2. A tool for adjustably mounting an object to a fixture, the tool comprising:

a tine shaped to support the object;

a bolt affixed to the tine having a plurality of engagement elements spaced apart along a bolt body;

a nut configured to be selectively retained at a plurality of positions along the bolt body corresponding with one or more of the plurality of engagement elements;

a base configured to secure the nut to the fixture such that movement of the nut between the plurality of positions correspondingly adjusts mounting of the bolt relative to the fixture and in turn the object supported on the tine, thereby adjustably mounting the object to the fixture;

wherein a first distal end of the bolt includes a head having an outer diameter larger than both of an outer diameter of the bolt body and an inner diameter of the nut and wherein a second distal end of the bolt is permanently affixed to the tine, thereby limiting the nut to movement along the bolt body between the head and the tine;

wherein the plurality of engagement elements are interconnecting radial threads shaped onto the outer diameter of the bolt body; and

wherein the nut includes an engagement mechanism operable between an engaged position and a disengaged position, the disengaged position disengaging the engagement mechanism from the threads so as to allow the nut to move along the bolt body and the engaged position engaging the engagement mechanism with one or more of the threads so as to secure the nut from moving thereafter along the bolt body.

3. The tool of claim 2 wherein the engagement mechanism when in the disengaged position permits the nut to be moved from a first position of the plurality of positions to a second position of the plurality of positions offset from the first position without being rotated.

4. A tool for adjustably mounting an object to a fixture, the tool comprising:

a tine shaped to support the object;

a bolt affixed to the tine having a plurality of engagement elements spaced apart along a bolt body;

a nut configured to be selectively retained at a plurality of positions along the bolt body corresponding with one or more of the plurality of engagement elements;

a base configured to secure the nut to the fixture such that movement of the nut between the plurality of positions correspondingly adjusts mounting of the bolt relative to the fixture and in turn the object supported on the tine, thereby adjustably mounting the object to the fixture;

wherein the tine is shaped to include an elongated central portion having first and second branches extending therefrom so as to be characteristically T-shaped; and

wherein a lower section of the central portion is angled relative to a longer, upper section of the central portion and wherein the first and second branches extend from a bottom, distal end of the lower section in opposite directions.

5. The tool of claim 4 wherein the affixation of the base to the nut orientates the bolt to be characteristically perpendicular to an elongated axis of the fixture and wherein the first and second branches extend from the central portion so as to be characteristically parallel to the elongated axis of the fixture.

6. The tool of claim 5 wherein the fixture is a predominately circular bar raised above a support surface and the base is shaped as a tube having an inner diameter slightly larger than an outer diameter of the bar such that the nut is free to slide along and to rotate about the fixture until either of the first and second branches or an upper, distal end of the upper section abut the support surface.

7. A system for testing an electromechanical device of the type having a radial mounting bracket with an aperture generally perpendicular to an axis of a pulley, the system comprising:

a tester including;

i) a belt drive with a belt operable to drive and/or be driven by the pulley to facilitate the testing;

ii) an interface operable to exchange electrical signals with the electromechanical device to facilitate the testing; and

iii) a fixture having an elongated member offset from a support surface; and

a tool for adjustable mounting the electromechanical device to the fixture, the tool including;

i) a tine having an upper portion shaped for receipt within the aperture and a lower portion shaped to rest against the support surface;

ii) a bolt affixed to the tine having an elongated bolt body;

iii) a nut configured to be selectively positioned along the bolt body at at least a first position and a second position; and

iv) a base configured to secure the nut to the elongated member such that the tine is positioned at a first offset from the elongated member when the nut is in the first position and at a second offset from the elongated member when the nut is in the second position, whereby the first offset produces a first tension between the belt and the pulley and the second offset produces a second tension between the belt and the pulley different from the first tension.

8. The system of claim 7 wherein:

the bolt includes a plurality of engagement elements spaced apart along the bolt body, including a first engagement element at the first position and a second engagement element at the second position; and

the nut includes an engagement mechanism operable to;

i) engage the first engagement element to prevent movement therefrom;

ii) disengage the first engagement element to enable movement therefrom toward the second engagement element; and

iii) engage the second engagement element to prevent movement therefrom.

9. The system of claim 8 wherein the engagement element is operable to engage the first engagement element and thereafter disengage the first engagement element to enable the nut to move to the second engagement element without requiring the nut to be rotated.

10. The system of claim 9 wherein the plurality of engagement elements are interconnecting threads extending in an uninterrupted manner from at least the first engagement element to the second engagement element such that two or more threads are included between a first thread corresponding with the first engagement element and a second thread corresponding with the second engagement element.

11. The system of claim 7 wherein the lower portion of the tine includes at least one branch longer than a width of the aperture extending laterally from the lower portion.

12. A tool configured to adjustably position a pulley included on an electromechanical device relative to a belt drive included on a tester of the type having an elongate fixture disposed above a support surface, the tool comprising:

a first member having an upper portion shaped for engaging the electromechanical device and a lower portion shaped for engaging the support surface;
