If you ask most people what makes a good carpentry project, they’ll say things like “quality wood,” “clean cuts,” or “a nice finish.” Rarely will anyone mention screws. Yet ask any seasoned carpenter in Los Angeles, and they’ll tell you—the screws are what make or break a project. Literally.

Think about the moment you flip a switch in your Los Angeles home. Maybe it’s turning on the porch light after a long day, charging your phone by the couch in your home in Echo Park, or dimming the chandelier for a family dinner in Glendale.
