Order AN960PD-"Size" where size is -4,-6, -8, -10, -416 (1/4") etc. Add "L" to the end for the light or thin series. The applications where I used aluminum washers, verses steel, include: Shear (push rod ends) Non structural (mounting strobe power supply) Anything to composite (pressure bulkhead) Use steel where vibration or shock loads are high (engine, prop & landing gear). Keeping an airplane light during construction is a battle of grams, not kilos. Before putting any part on the airframe, ask yourself "Is there anything I can remove from this part without compromising strength or function?". I even took the air switch for the door seal to the belt sander and ground off several ounces of brass that was useless load.
