Suits doors: up to approximately 38-40mm thick (depending on handle/escutcheon/rosette depth on both sides). Configuration: male bolt threads INTO female sleeve through the door. Drive: slotted head — requires flat-blade screwdriver to install/remove. Note: M3 is the older British thread standard — common on Victorian, Edwardian, and retro-style handles.

Each set: 1 male M3 × 50mm slotted bolt + 1 female connecting sleeve. Finish: Silver — bright silver/nickel finish. Variation options: this product is available in Brass and Silver finishes in Pack of 2 or Pack of 4.
- APPLICATIONS — DOOR HANDLE & KNOB ATTACHMENT Use cases: older British interior door handles, Victorian door knobs, period escutcheons, antique-style mortice handles, retro lever handles, restoration projects with original-spec hardware. Sectors: residential interior doors (especially older properties), restoration, period property refurbishment.

- INSTALLATION GUIDANCE 1. Position the handle/escutcheon on the front face of the door. 2. Insert the female sleeve through the spindle hole from the back of the door. 3. From the front, insert the male slotted bolt into the sleeve through the front handle/escutcheon. 4.
