John Hassall supplies custom formed and machined parts utilized in a variety of military and defense-related applications. The requirements of our customers often call for the use of exotic materials with extremely close tolerances and demanding performance criteria. When cold heading or hot forging cannot, by that process alone, create a unique shape or hold a critical tolerance, John Hassall can provide a part to the most demanding of specifications by employing a variety of secondary operations, including:
- Threading (flat die and tri-roll) with and w/o heat
- Multi-axis CNC machining
- Centerless and specialty surface grinding
- Broaching, milling and drilling
- And more…
John Hassall supports the defense industry with a 100% vertically integrated US-based manufacturing factory, which is complemented by an in-house heat treating facility and metallurgical laboratory, certified to NADCAP, ISO 9001:2008, and AS 9100.
