3ds max karabiner screwgate - Screwgate oval karabiner by UVSAR

Screwgate sleeve has a knurled surface created using a displacement map (texture supplied as an accompanying file) and internal spring/pin mechanism. Screwgate sleeve and gate bar have accurately-modeled threads. Max9 version has these parts parameter-wired to the gate bar so they correctly react to the open/close/unscrew actions.
