Manufacturing Process: Heat Treat & Shot Peening
Following the basic shaping, material is heat-treated to desired levels. This crucial process is done entirely in-house to assure total quality control. ARP uses special vertical racks to hold each piece individually and assure complete 360° penetration. This is far superior to commonly-used methods of dumping items into a large bin and batch-treating.


Fasteners are shot-peened after heat-treatment to remove any surface irregularities and improve overall external integrity.
