Cup Head Insulation Pins is a mild steel fabricated part made up of a weld pin and a staked-on
speed clip, or retaining washer.
While some variations of material are available, the most popular style for cup head insulation
pins is a mild steel weld nail with a galvanized-coated mild steel retaining washer.
