Screw-On Self-Close Hinge For Inset Doors on Face-Frame and Frameless Cabinets

This Grass Tiomos concealed hinge is built for inset doors that sit flush inside the cabinet opening, with a self-close spring and screw-on mounting for both face-frame and frameless construction.

Key Features

• Inset door geometry positions the door flush within the opening, producing an even reveal on all four sides.
• Self-close spring pulls the door shut automatically from the last few degrees of travel.
• 110 degree opening angle delivers the standard everyday swing for interior cabinet access.
• Screw-on mounting fastens the hinge arm directly to the base plate with screws for a fixed, secure connection.
• Three-way adjustment moves the door up to 3mm in height, side, and depth to dial in an even reveal after installation.
• Fits face-frame and frameless cabinets when paired with the appropriate Grass Tiomos base plate, sold separately.

Hanging Doors That Sit Inside the Opening

An inset door lives inside the cabinet opening rather than over it. That design places a tight, consistent gap around all four edges, which makes the hinge geometry critical. This Tiomos hinge carries the full-crank arm configuration that holds the door in the correct inset position as it swings through 110 degrees, clearing the opening without racking against the frame. The 35mm cup bores into the back of the door at a 45mm bore pattern, and the arm connects to a Grass Tiomos base plate mounted to the cabinet. That plate is sold separately and must be a Grass Tiomos plate: plates are brand and series specific, and a plate from another brand will not engage the Tiomos arm correctly. Maximum door thickness for this hinge is 24mm.

Steel Build and a Nickel Finish

The hinge is plated steel in a nickel finish. The screw-on arm connection is the right choice where a mechanically fixed attachment matters more than tool-free removal, common in commercial casework and production runs where doors are not expected to come off once the job is done. The three-way adjustment range, plus or minus a few millimeters in all three axes, handles the real-world variation that comes with fitting doors precisely inside an opening.

Where This Hinge Belongs

Inset hinging is most at home in furniture-grade cabinetry, traditional kitchens with a flush-face aesthetic, and built-ins where the reveal is a visible design detail rather than a background element. This hinge suits cabinet shops and millwork operations fitting face-frame or frameless boxes to an inset specification. Because the self-close spring pulls the door shut but does not cushion the contact, it is the practical, lower-cost closing option for inset work where a damped soft-close is not required. For installations that call for a quieter, damped close on inset doors, a Tiomos model with integrated soft-close is the alternative to specify.

Common Questions

A Flush Face, Closed Cleanly

Specify this hinge where the design calls for inset doors that close on their own, sit square inside the opening, and hold that look across a run of cabinets.
