PennEngineering® has been approved by the Defense Logistics Agency as a supplier of Class 2 threaded fasteners in accordance with the stringent QSLM (Qualified Suppliers List of Manufacturers) program. 

This along with the Class 3 approval awarded in 2007 authorizes PennEngineering to fulfill government contracts which specify PEM® brand threaded fasteners and Atlas® brand threaded inserts.
