MOZCORN 6-Pack Black 4-Inch Heavy-Duty Stainless Steel Door Hinges | Ball Bearing, 150LB Load

Overview

Upgrade any door with the MOZCORN 6-Pack Black Door Hinges. These 4-inch hinges combine rugged metal, corrosion protection, and quiet operation, offering a practical upgrade for homes and small offices. Each hinge uses a thicker 2.5 mm steel core and a matte black finish that resists everyday wear, so appointments and daily routines continue without distraction.

Designed to support heavier doors, these hinges can handle up to 150 pounds per hinge. For most doors in residential or commercial settings, two or three hinges deliver balanced support and dependable performance across years of use. The stainless steel body, paired with a durable powder coating, helps resist rust and coating wear in challenging environments.

What you get with this 6-pack goes beyond the hardware. The package includes mounting screws for quick installation, and you may want longer screws when upgrading older frames to ensure a secure hold. The matte black finish maintains a clean, contemporary look that fits many architectural styles.
