3/8"-24 Hex Flange Cone Locknut, Two Opposite Oval Lock, Grade G, Phosphate & Oil Finish

Manufactured to Grade G specifications, it is ideal for high‑strength and structural applications requiring fine threads. The integral flange distributes clamping force evenly and eliminates the need for a washer, while the phosphate and oil finish provides initial corrosion protection and improved installation lubricity.
