The Latch Pin is mounted into each side of the Latch with a square, tapered spline geometry. It provides the rotational axle for the latch and includes geometry to engage a hard stop for limiting rotation of the Latch.
This part is a zinc diecasting and is first trimmed, then mechanically deburred. The part is without any surface plating and will become a duller grey color over time due to oxidation of the raw zinc surface. This is completely normal and does not affect part function.
