DMM is bringing an old favourite back to the market. The high demand for these nuts is because their complex offset shape offers placement opportunities when nothing else will fit. Pin scars take this shaped gear well. These nuts are based on the famed HB Alloy Offsets and were produced using modified versions of the original HB dies. In typical DMM fashion we have brought them into the 21st century with colour coded sizing, recessed wires, bonded heads to stop slippage from autumn 08 and lightening holes in the largest two sizes.
