John Hassall supplies custom formed and machined parts utilized in a variety of marine related applications. The requirements of marine customers vary from simple standard fasteners, to weather-resistant stainless steel parts, to specialty items made from exotic materials with extremely close tolerances and demanding performance criteria. Either way, we have the capability to cold head, hot forge, or machine from bar the part you need in the most cost effective manner possible. Further, 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 marine industry with its US-based manufacturing factory, which is complemented by an in-house heat treating facility and metallurgical laboratory, certified to NADCAP and AS 9102 standards. Our quality systems are compliant with MIL-I-45208A and MIL-DTL-1222J.
