WingNut The slotted engine nut is a specialized type of fastener designed to provide a secure and reliable connection in various mechanical applications, particularly within engine assemblies and motor systems. Its unique design, featuring slots at the top, allows for the insertion of a cotter pin or safety wire, preventing loosening and ensuring the integrity of critical components.GenuineNutM4Slottedfor MAG engines: compatible with models 1017SRL, 1018SRL, 1029SRL, 1021SRL, 1014SRL. OEM No. 1113 020. May show signs of storage. While often referred to interchangeably with castle nuts, there are subtle differences in their construction and typical applications.
What is a Slotted Engine Nut?
A slotted nut is fundamentally a hexagon nut that has slots machined into one of its ends. These slots are typically located at the top surface of the nut and are designed to align with a drilled hole in the bolt or stud. Once the nut is tightened to the desired torque, a cotter pin is inserted through the slots and the hole in the bolt, effectively locking the nut in placeYamaha Pwc Wave Runner Slotted Engine Mount Nut ....

Technical Specifications and Considerations:
When selecting a slotted engine nut, several parameters are important:
* Thread Size: Nuts are specified by their thread size, such as M16 x 1Slotted Nuts, Engine, 1968-72 Pontiac.5 or 3/8-24. For example, a Lycoming slotted nut might be specified as STD-872 with a 3/8-24 thread.
* Material: Typically made from steel, these nuts are also available in other materials like 304 stainless steel round nuts for corrosion resistance.
* Compliance: ASME/ANSI B18.STD-872 LYCOMING SLOTTED NUT2.2 Hex Slotted Nuts are a common standard, ensuring dimensional accuracy and performanceCastle & Slotted Nuts - Fastener Specifications.
* OEM Part Numbers: For specific equipment like Cummins hexagon slotted nuts, OEM part numbers like 146650 are crucial for identification. Likewise, a Yamaha PWC Wave Runner slotted engine mount nut will have a specific part number such as EW2-62733-09.
Installation and Removal:
The installation of a slotted engine nut involves tightening it onto a bolt or stud. The key is to tighten it to the correct torque and then rotate it slightly, if necessary, to align the slots with the hole for the cotter pin. Removal typically requires a pin wrench if the nut is difficult to grip, especially in tight spaces like a blower motor switch where a slotted nut might be used.
In summary, the slotted engine nut is a vital component in numerous mechanical systems, offering a secure fastening solution through its unique slotted design and compatibility with locking pins. Understanding its variations, applications, and specifications is essential for ensuring the safety and reliability of any assembly where it is employed.
