Project Description

220 pieces of these custom stainless steel precision pins were produced domestically for our aerospace customer using 303 stainless steel material. Original specifications on the drawing called out for 303 stainless steel per AMS 5638 but we obtained a deviation approval to provide the part using a similar AMS 5640 V Type 1A spec material instead. Passivation per AMS 2700, method 1, type 4, class 2 was done to complete the parts prior to QC inspection. Overall length measures at 1.131″ +/-.005 and the shaft diameter is set to .074-.075″. The width of the flattened section on one end reaches a diameter of .084″ +/- .005. The other end is rounded at R .078.

We were able to complete these parts about 1 month before the required date – not having a lot of secondary operations and finish related tasks made the lead time much easier to control.
