Overview

Upgrade interior doors, closets, and cabinets with the TDCHINGES 30-pack of rounded matte black hinges. These 3.5-inch hinges feature a 5/8-inch radius and six mounting holes per leaf, designed for versatile mounting and reliable movement. The set includes 180 screws to help speed up installation, so you can refresh multiple doors in a single project without running back to the hardware store.

Designed for smooth operation, these hinges rotate up to 270 degrees, enabling flexible fits in tight spaces and awkward door openings.

Extra-long screws are included to align with existing hole patterns when you’re updating hardware on older frames, reducing the need for additional drilling or rework.

Performance and installation considerations

In addition to sturdy iron construction, TDCHINGES hinges are paired with aerospace-grade lubricants designed to withstand heat and reduce friction, helping maintain smooth movement even in warmer environments. While no hinge can guarantee silent operation in every installation, the plain bearing design aims to minimize sticking and squeak over time with proper mounting.
