Grade G Hex Flange Cone Locknut Without Serration, "2 Opposite Oval Lock", Phos & Oil (Inch)
Our Grade G Hex Flange Cone Locknuts with Two Opposite Oval Locking Features and Phosphate & Oil finish are high‑strength, all‑metal locknuts engineered for applications requiring superior resistance to vibration and loosening. Manufactured from carbon steel and heat‑treated to Grade G specifications, these locknuts deliver high tensile strength and durability for demanding mechanical and industrial assemblies.
The cone lock design with two opposing oval thread distortions creates a prevailing torque that resists loosening under vibration, shock, and dynamic loads. As an all‑metal locking nut, this design maintains locking performance in elevated temperatures and harsh environments where nylon insert locknuts may fail. The non‑serrated hex flange provides an integrated bearing surface that distributes load evenly without damaging mating surfaces or coatings. Finished with phosphate & oil, these locknuts offer corrosion protection and consistent torque characteristics during installation.
Designed for reliability and installation efficiency, Grade G Phosphate & Oil Hex Flange Cone Locknuts are commonly used in automotive assemblies, machinery, equipment manufacturing, heavy‑duty industrial installations, and maintenance operations. The flange eliminates the need for a separate washer, reducing part count and simplifying assembly, while the oval‑lock cone feature ensures long‑term joint security in high‑vibration environments. Available in a range of inch thread sizes, these locknuts provide a dependable fastening solution for OEM production, repair, and service applications where strength, heat resistance, and vibration control are critical.
