Freightliner Hex Jam Nut 5/8-18 Part No: 23-09254-007

Freightliner part 23-09254-007 is a hexagonal jam nut used across various truck and chassis assemblies. Catalogs describe it as a Nut-Hex, Jam, 5/8-18, Grade 5, Zinc, indicating a thin-profile nut designed to be run up against a standard nut to lock it in position. The Grade 5 steel body provides ample tensile strength for typical mounting and clamp applications, while the zinc plating adds corrosion resistance for on-highway use. Hex jam nuts like this are commonly applied wherever precise preload must be maintained and vibration could otherwise back off the main nut, such as suspension brackets, linkage points, and general hardware locations on Freightliner tractors.
