Tap Extension: 3/8" Tap, 5" OAL, 0.381" Tap Shank Dia MPN:96095

The 4140 alloy steel round rod measures 5/8 in diameter, with a length of 6 feet making it ideal for heavy machining tasks such as cutting, drilling, and turning requiring high strength at various tempers suitable to its heat-treated condition. Its medium carbon content adds rigidity to the material during cold working procedures while providing resistance against deformation under elevated temperatures when heat treating or hot rolling is needed prior to final finishing. Applications in manufacturing aerospace components, drive shafts for vehicles, gears, valves or machinery parts require strong alloy steels that can hold up well against stress at low operating temperatures hence why 4140 is commonly chosen by industries seeking maximum tensile strength and ductility with wear resistance without sacrificing toughness.
