Part name identification help - WinkHaus side locks?
According to WinkHaus, I believe the parts you are talking about are named as follows (quoted material)

The Winkhaus roller cam
Cotter pin locking systems are an
easy-to-install alternative for main or secondary entrance doors made
of wood or plastic. The lock has up to four additional drawing points
and thereby guarantees a tighter seal and improved protection against
opening of the door by force.
The roller cams, adjustable manually,
allow the door situation to be adapted accordingly and thus facilitate
optimum locking. This allows door design tolerances to be balanced
out.
Winkhaus mushroom pin
The mushroom pins slide behind the
security keep when the door is bolted. This prevents the door leaf and
frame from being pulled apart horizontally. The contact pressure can
be conveniently adjusted using a hexagon socket. This guarantees easy
bolting and high door movement in the frame - a major plus for
security and tightness at the door element.
