MP35N lock nuts are known for their extraordinary strength and are the strongest nuts we offer at Extreme Bolt. MP35N nuts 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 lock nuts, they are also exhibit good corrosion resistance and can resist most mineral acids, hydrogen sulfide, seawater and salt spray environments.
MP35N nuts are also resistant to high temperature oxidation and could operate in environments up to 800°F and still maintain much of its strength.

MP35N Locknut Features and Beneifts

A MP35N locknut resists loosening from vibrations and torque. One of the most common styles is a prevailing torque locknut. This kind of MP35N locknut has a prevailing torque feature which deforms elastically, preventing it from freely spinning like a standard nut.

The two most common and reliable forms of prevailing torque locknuts are the flexloc style and the polymer insert lock nut. A MP35N flexloc nut is all-metal in composition with a segmented collar that creates six “locking fingers,” that act as a spring. MP35N polymer insert lock nuts are often referred to as nylon insert locknuts, although various high performance polymers can be used for the screw threads to “bite into.” Both flexlock and polymer insert locknuts are available in both hexagonal and 12 point configurations.

· Can be used at high temperatures

· Distributes load evenly due to the fact that it is manufactured as one solid piece.

· Is THE most reliable all-metal self-locking nut.

· As it is all metal, it is best for high temperature or corrosive applications

· One of the only all-metal lock nuts that is certified to 15 cycles of prevailing torque – which is military standard.

· Overall the most reliable locknut, with the only limitation of application temperature

· Best for low temp applications, typically less than 350°F

· Various polymers inserts available (Nylon, Vespel, PVDF, etc.) for higher temp. or corrosive applications.

· Excellent reusability – can reliably be re-used 15 times

· Eliminates galling and cold-welding common with exotic alloys

Other all metal lock nuts available include the MP35N stover and elliptical styles. Though these styles are often a cheaper initial cost, they are less reliable than the flexloc style. As these styles delivering less prevailing torque cycles and often result in more failures, the flexloc style is a better investment for both reliability and cost savings.

 

 

MP35N Chemistry, Spec 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
