Trying to refresh the original Magnum 500 rims. What type of black should these be? Flat or gloss?

For 1970s Mopar vehicles with steel wheels, the most common lug nut type is the 1/2-20 thread with a 60-degree conical (acorn) seat, typically found on original equipment (OE) and aftermarket steel wheels. These lug nuts often have a 3/4" hex size. Left-hand thread lug nuts were used on the left side of full-size, B-body, and E-body Mopars through 1970.

Lug Nut Details:
  • Thread Size: 1/2-20 (standard thread).
  • Seat Type: Conical (60-degree).
  • Hex Size: Typically 3/4".
  • Material: Steel, often with a chrome plating.
  • Length: Varies, but commonly around 1.38".
  • Left-Hand Thread: Used on the left side of some Mopar models through 1970.
Important Notes:
  • Verify Compatibility:
    Always confirm the lug nut type and thread size with your specific vehicle's specifications, as some models or aftermarket wheels may vary.
  • OE vs. Aftermarket:
    OE (original equipment) steel wheels often use a lug nut that secures a hubcap or center cap. Aftermarket wheels may require a different lug nut style.
  • No Lubrication:
    Avoid using lubricants or anti-seize on lug nuts or studs, as this can affect torque values and lead to loosening.
  • Proper Torque:
    Always torque lug nuts to the manufacturer's specifications to ensure safe and secure wheel attachment.

Already replaced the left-hand threads. Will need to get new lug nuts.

You can carefully clean up the conical lugnut seats in the wheels with a 1/2" 60° countersink bit. Link is to Amazon.
This can remedy minor seat issues but does take away a small amount of seat material which slightly enlarges the 1/2" holes.
