Experience the Next Generation
in Socket Wrench Technology
Zero-Degree®
featuring Mag-Drive™ technology
Longer Life
Patented Design
Exceeds ANSI Standards
Next Generation Technology
Superior
feel
Free wheeling movement provides more control and more precise feel
Free wheeling movement prevents having to hold the socket when starting or working with loose bolts
Superior Durability and Strength
Laboratory tested and evaluated with no detectable damage or wear after 50,000 strokes under load in both directions and failure torques 164+% of ASME standards.
Comparable high-end ratchet socket wrenches fail with badly worn teeth and severe slippage after only 27,300 strokes under load.

Technology
Magnetic drive direction selector provides smooth operation allowing for finger only direction changes on all sizes of wrenches

Rollers
Collector
The Zero Degree® wrench is designed to use a hexagonal inner cam/driver that is integral with the square socket drive.
The cam/driver is surrounded by six cylindrical rollers that are, in turn, enclosed by a hardened cylindrical race that is machined into the forged steel handle.
The rollers are held in position by a non-ferrous metal cage that shifts the wrench between forward and reverse.
Magnets (a newly patented design) hold the selector in position and two snap rings retain all of the components in the pocket in the head of the handle.
The roller clutch design uses cam rollers in place of teeth to provide a Zero Degree® swing arc, a Zero Degree® back-drive, significantly longer tool lifetimes, and greater than ANSI strength.
Titanium
Tuff®
Proprietary Titanium Fusion Impregnation Plating
Strengthens the tools outside surface from dents and scratches
Strengthens the tools integral steel working parts for longer wear and smoother performance
Eliminates corrosion from acids and salts
Long lasting lustrous gold-colored finish
Gold color is patent protected on the socket wrench and pending on the combination wrenches
Superior
Operation
The Zero-Degree clutch roller design positively engages immediately in the drive direction, providing an instant grip and no slop.
Superior
Performance
Extremely effective in tight area, with less than 1° of arc, compared to ratchet gear socket wrenches that have an average of 5° to 12° degree swing arc.
Independently field-tested to be an average of 30% faster in tightening and loosening due to free play and more swing arc in tight places.

Minimum Proof Torque and
Failure Torque Testing Results
Driver Size | Required Minimum Proof Torque (lbf-in.) | Applied Torque at Failure (lbf-in.) | Percent of Required Torque |
|---|---|---|---|
1/2" | 4,500 | 6,706 | 167% |
3/8" | 1,800 | 2,700 | 167% |
1/4" | 450 | 699 | 164% |
Cycle and Proof Torque Testing
Cycle and Proof Torque testing per ASME B107.110-2012 on 1/4”, 3/8” & 1/2” drive Zero Degree ratchets.
One ratchet of each size was cycle tested per paragraph 10-3.10 which includes proof torque testing after completion of cycle testing.
Cycle testing was conducted by applying a repeating load at the midpoint of the grip section for each ratchet at a frequency of 1 Hz.
After cycle testing the ratchets were subjected to Minimum Proof Torque testing and then loaded to
failure.
