Both these items were return to sender for reasons unbeknown to me. I received a notification of a credit but the credit amount is not equal to my costs. The credit fails to include the postage costs. I have sent 2 previous emails on this subject with no clarification as to why the postage costs have not been credited, after all the service was in my mind not used.
I have been using Aircraft Spruce for the last 10 + years no problems until now. Still waiting on some clarification to my email. This order has been ordinary to say the least. As for reorder I have sourced these items else where.

Aircraft spruce invite me to review the recently bought washers, so I will do so. The gold color color washers are perfectly flat on both opositise sides and completly round respect to the perpercicular axis , maintaining a constan inner and outer radii. By ussing them you can safetly separate the piece or pieces from the bolt head or nut. I do stongly recomend the aircraft spruce washers for installations of this kind.
