Selby free swinging inset pivot hinge is a steel pivot hinge in a black oxidized finish with a 9mm nylon pivot bushing, so it provides a sturdy pivot point with a low-friction bearing surface that keeps the door swinging smoothly. As a semi-concealed hinge in the specialty hinges category, it keeps much of the hardware out of sight, which helps maintain a cleaner cabinet or furniture appearance while still giving straightforward access to the pivot. The hinge accommodates door thickness of 1/2 inch to 5/8 inch, which makes it suitable for a defined range of inset doors where those thicknesses are standard. This model is identified by manufacturer part HT57S and is supplied by Selby Furniture Hardware, which helps match it accurately with drawings or existing hardware references.
This steel pivot hinge is designed for top and bottom door mount using a 23/64 inch (9mm) diameter hole to accept the nylon pivot bushing, which sets a precise interface between the door and the pivot hardware for clean rotation. The hinge accommodates door thickness of 1/2 inch to 5/8 inch, so installers can work within that range knowing the pivot geometry is matched to those door edges. Slotted screw holes provide side-to-side adjustment, which lets the mounted hinge shift slightly across the screw slots to bring the door into line with surrounding parts. As a semi-concealed hinge, its mounting style leaves much of the hardware out of direct view while still allowing straightforward access to screws and adjustment points when aligning the door.
This Selby Furniture Hardware pivot hinge is categorized as a semi-concealed specialty hinge, so it fits installations where a traditional butt hinge is not desired and a pivoting action from the top and bottom of the door is preferred. The hinge is designed for inset doors with thickness from 1/2 inch to 5/8 inch, meaning the door edge dimensions fall in a defined band that matches the hinge layout and the position of the 23/64 inch (9mm) bushing hole. Using a steel body with a 9mm nylon pivot bushing, the hinge places the load on a metal structure while the nylon component manages the pivot movement, which supports a consistent swing cycle. The top and bottom door mount arrangement places the pivoting points at the ends of the door, which sets up a vertical axis near the door edge and helps the door track consistently through its motion path.
The 23/64 inch (9mm) diameter hole specification for the nylon bushing gives a clear drilling size that ties the door preparation directly to the hardware dimensions, so repeated doors can be machined to the same standard and hung with consistent results. Slotted screw holes are built into the hinge, which allows the hinge position to shift laterally during installation; this side-to-side adjustment gives the installer room to move the door slightly within the opening to achieve even gaps. The combination of steel construction and nylon pivot bushing creates a pivot assembly where the steel supports structural loads and the nylon element defines the rotation interface, which helps maintain a consistent feel at the door edge. As a semi-concealed hinge with a black oxidized finish, it presents only limited hardware to view and the dark surface blends with similar finishes, which supports a uniform appearance across a run of cabinets or furniture pieces using the same HT57S pivot hinge layout.
The Selby free swinging inset pivot hinge accommodates door thickness of 1/2 inch to 5/8 inch, which lets it serve a defined group of inset doors built within that thickness range.
The steel pivot hinge uses a 23/64 inch (9mm) diameter hole in the door to accept the 9mm nylon pivot bushing, so drilling that size sets the correct interface for the pivot.
The HT57S pivot hinge is a top and bottom door mount design, placing its pivot points at both ends of the door to support vertical alignment during door movement.
The steel pivot hinge uses slotted screw holes that allow side-to-side adjustment, giving the installer the ability to shift door position for better alignment in the opening.
The black oxidized finish on the pivot hinge provides a dark surface that visually blends with darker casework, helping the semi-concealed hardware remain less noticeable in the installation.
The 9mm nylon pivot bushing works with the steel hinge body to define the pivot point, which supports smoother swinging movement by reducing direct metal-on-metal contact at the pivot.
The HT57S steel pivot hinge from Selby Furniture Hardware combines a black oxidized finish, a 9mm nylon pivot bushing, and semi-concealed construction, so it suits projects calling for a free swinging inset pivot point with restrained hardware visibility. Its accommodation of 1/2 inch to 5/8 inch door thickness pairs with the specified 23/64 inch (9mm) hole and slotted screw holes, giving defined drilling and adjustment steps when laying out inset doors. For work requiring a top and bottom door mount pivot hinge in this size range, this Selby free swinging inset pivot hinge offers a clear set of dimensions and features to align with project drawings.
