One of the highest strength alloys available to industry

MP35N set 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 set 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 set screws are often found are: aerospace, defense, marine, chemical processing, oil and gas and medical.

MP35N Set Screw Features & Benefits

MP35N set screws are unique in that they have no screw head, meaning that they have no protruding part past the threaded shaft. They are thread only and are available with a socket or slotted driver insert at one end. Set screws are used to secure an object within or against another object. Typically they secure a rotating part such as a gear or shaft. MP35N set screws are driven through a threaded hole in the rotating part until it is tight against the inner object, preventing from moving relative to the outer object. Set screws are available with various points depending on the application.

cup point

Cup Point 
This is the most commonly used set screw and is identified by a cup-shaped indentation on one end. MP35N cup points are typically used for a quick, semi-permanent or permanent applications where it is acceptable to cut the cup point edge of the screw.

 

Cone Pointcone point
A cone point is easily identifiable by its sharp cone-shaped point – just like an ice cream cone. MP35N cone point set screws deliver the strongest clamping force due to the deep penetration of the point. As a result they are used for permanent assembly.

 

flat point setFlat Point

The cheapest and simplest of the set screw point styles, this screw has a flat surface on the bottom of the screw. This type is used when you need the ability to frequently change parts and require minimal shaft deformation.

 


MP35N Chemistry, Specs and Heat Treatments

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. 

MP35N Specifications:  AMS 5844, AMS 5845, AMS7468, ASTM F562, NACE MR0175
