- MP35N button head cap screw features and benefits
MP35N button head cap screws are known for their extraordinary strength and are the strongest screws we offer at Extreme Bolt. MP35N screws owe their extraordinary strength to a unique alloy combination of nickel, cobalt, chrome and molybdenum and have ultimate tensile strengths that range from 227 ksi to 294 ksi (with age hardening).
Beyond the strength of MP35N button head cap screws, they are also exhibit good corrosion resistance and can resist most mineral acids, hydrogen sulfide, seawater and salt spray environments.
MP35N screws are also resistant to high temperature oxidation and could operate in environments up to 800°F and still maintain much of its strength.
Applications where MP35N button head cap screws are often found are: aerospace, defense, marine, chemical processing, oil and gas and medical.

MP35N button head cap screws combine the similar shape of a pan head with the driver of a socket head. The socket driver is ideal for low clearance applications that require a large area clamping face. Compared to a standard socket head cap screw, MP35N button heads have a lower and wider profile. This can be useful when the clamping material is too thin to counter-bore.
- Wide bearing surface for clamping
- Low profile head
Heat Treating & Aging: MP35N is usually supplied in heat treated and cold drawn condition AMS 5844. In this state the MP35N can be worked into the desired fastener form and aged to the AMS 5845 specification. Once aged, the MP35N material could achieve it full strength potential.
