We had these custom black aluminum spacers manufactured for an automotive research facility using 6061-T6 aluminum material with black anodize finish.  The inside diameter measures 5.3MM and the outside diameter 13MM.  The overall length is 80MM and tolerance on all dimensions is +/- .10MM.  Production was done domestically with a relatively quick turnaround time of 4 weeks including the anodizing process.

Our long standing partnerships with over 1,000 specialty manufacturing factories all over the United States and abroad based on decades of custom hardware & fastener production history, in combination with the flexibility of blanket purchase arrangements, allows us to fully cater our customers’ custom fastener specification and procurement requirements.
