MP159 Hex Head Bolts
As aerospace engineering advances, so must the materials to meet the technological requirements of this industry. Bolts made from MP159 have been developed to provide a solution to high temperature, high strength components. MP159 hex head bolts offer strength capabilities similar to other Cobalt Alloys (MP35N) but can be used at much higher temperatures - up to 1100°F, compared to MP35N’s usable limit of 800F. In addition, MP159 hex bolts can be used beyond 1100°F in short term situations.

MP159 hex bolt features & benefits

Key Benefits

High ultimate tensile strength of 275 ksi and yield strength of 265 ksi (Cold Worked and Age Hardened) combined with excellent ductility and toughness
Similar corrosion resistance compared to MP35N which is usable in mineral acids, hydrogen sulfide, seawater and salt spray environments.
Excellent fatigue resistance and creep strength at elevated temperatures
Excellent resistance to crevice corrosion, stress corrosion cracking and hydrogen embrittlement

Applications

The aerospace industry relies on MP159 hex bolts for its most advanced gas turbine and jet engines, rocket boosters and jet propulsion systems.
Power generation and chemical processing utilize MP159 hex head bolts for applications that demand high strength at extreme temperatures.

MP159 Hex Head Bolt Features and Benefits

It is important to differentiate between a Incoloy hex head bolt and hex head cap screw. Often people assume they are the same, but they are actually very different fasteners in terms of how they are manufactured, as well as from an application perspectiv. Regardless of your choice, MP159 hex heads offer strong, stable joints because of their large head service.

The Hex Comparison

Hex Head Bolts	Hex Head Cap Screw
Hex bolts have a flat end and lack the washer face under the head. Appropriate for when mechanical properties are more important than dimensional tolerances.	Features flat washer facing under the bolt head. Also called a finished hex bolt. Has tighter tolerances on the body dimensions. Best used for precise applications where tight tolerances on the body dimensions are required.
