Furniture Connectors & Cam Lock Fittings: Compatible Replacement Hardware for JYSK Furniture

A cam lock fitting is a two-part furniture connector consisting of a cylindrical cam housing and a matching connecting bolt, designed to join carcase components securely and detachably at a 90-degree angle.

During assembly, repair, or house moves involving flat-pack furniture from well-known brands such as JYSK, connectors can occasionally get lost or break under strain. Because this furniture relies on industrial standards, defective parts can be replaced accurately with standardised hardware. This guide provides the technical specifications needed to select the correct furniture connectors for carcases, drawers, and shelving units.

Key Purchasing Criteria for Furniture Connectors

To restore the structural integrity of a wardrobe or chest of drawers, replacement parts must match the existing drill holes precisely. A deviation of just one millimetre can lead to loose joints or damaged chipboard.

1. Drill Hole Diameter and Board Thickness

The core of the joint is the cam housing. The standard drill hole diameter in the panel face for most flat-pack furniture is 15 mm. Less frequently, primarily in delicate drawers, variants with a 12 mm diameter are used. Drilling depth is also crucial and depends directly on panel thickness. For standard chipboard with a thickness of 16 mm, a housing height of 12 mm to 12.5 mm is typically required. For a panel thickness of 19 mm, the housing height is usually 14 mm.

2. Connecting Bolt Length and Thread Type

The connecting bolt (also known as a cam pin or dowel) that pairs with the housing dictates the gap dimension of the joint. The most common drilling distance (the distance from the panel edge to the centre of the cam hole) is 24 mm or 34 mm. Connecting bolt threads follow three standard engineering formats:

• Euro thread: Designed for pre-drilled holes with a 5 mm diameter, matching the industrial System 32 standard.
• Wood thread: Cuts directly into a smaller pilot hole (usually 3 mm) or directly into the wood.
• Metric thread: Typically M4 or M6, requiring an insert socket in the panel, such as a threaded insert (Rampa-style) or an expanding socket.

3. Material and Load Capacity

Original fittings in budget flat-pack ranges are often made of plastic or lower-grade alloys. For long-term stability, especially in wardrobes or heavy sideboards, die-cast zinc (Zamak) is the material of choice for cam housings. The corresponding bolts should be manufactured from hardened steel. Plastic is primarily suitable for small, visible carcase connectors that do not bear heavy structural loads.

Overview of Types and Options

Different fittings are utilised depending on the position within the piece of furniture and the structural demands.

The Classic Cam Lock Fitting (Minifix System)

The standard concealed solution for almost all flat-pack furniture. It sits out of sight on the interior face of the carcase. The fitting acts like an anchor, pulling the panels together seamlessly as it turns. It absorbs tensile forces exceptionally well, though it is almost always paired with a standard wooden dowel (typically 8 mm x 30 mm) to handle shear loads.

Screw-On Carcase Connectors

These angular corner blocks, often made of plastic or metal, are positioned inside the internal corners of furniture. They do not require complex flat-bottomed recess drilling, as they are simply screwed onto the surface. They are ideal for retrofitting reinforcement or for repairs when the original chipboard hole has torn out. They are secured using suitable wood screws and furniture screws, typically with a diameter of 3.5 mm or 4 mm.

Worktop Connectors

For very thick panels (e.g. 28 mm to 38 mm), standard cam locks are insufficient. Worktop joint connectors are used instead, tensioned via threaded rods and curved metal clamping plates.

Which Connector for Which Application?

Selecting the correct replacement hardware follows clear technical logic:

• If a drawer front on a JYSK chest of drawers is wobbly or detaching: Choose a cam housing with a 15 mm diameter and a height of 12 mm. Check if the bolt is bent; if so, replace it with a steel bolt featuring a Euro thread.
• If the hole in the chipboard is completely torn out: A replacement cam lock will no longer grip. Switch to a screw-on metal carcase connector. Position it a few centimetres away from the original damaged area.
• If you are repairing and securing a filing cabinet: Alongside correct carcase fixings, locking mechanisms often fail. Replace old locks with a standardised furniture cylinder lock. Such furniture locks generally require a 19 mm or 20 mm hole in the front.
• If the piece of furniture will carry heavy loads: Always apply wood glue to the wooden dowels during assembly. In addition, align the unit precisely to minimise torsional stress on the connectors. Adjustable furniture legs help compensate for uneven floors.

Installation Guide: Disassembly and Assembly

Working with cam lock connectors requires the correct tools and precise handling to avoid stripping the fittings.

Required tools:

• Screwdriver with a Pozidriv (PZ2) or Phillips (PH2) drive.
• Rubber mallet.

Step-by-step assembly:

1. Insert the bolt: Screw the connecting bolt perpendicularly into the pre-drilled hole in the first panel. The thread collar must sit flush against the panel surface.
2. Join the panels: Insert the shaft of the bolt into the edge hole of the second panel until both components meet without gaps.
3. Fit the cam: Push the housing into the 15 mm hole. The small arrow on the face of the cam must point directly towards the inserted bolt.
4. Lock the joint: Turn the housing clockwise using the screwdriver. After approximately 180° to 210°, you will feel distinct resistance. The panels are now firmly locked together.

To release a cam lock fitting, turn the housing anti-clockwise until the arrow points back towards the bolt. For tight joints, tap the edge of the panel gently with a rubber mallet to separate the components.

Frequently Asked Questions (FAQ)

How do I release a stuck cam lock connector? Turn the housing anti-clockwise until the indicator mark points directly towards the bolt. If the housing remains stuck, do not lever it out with force. Instead, tap the adjacent wooden panel gently with the heel of your hand or a rubber mallet to release tension from the pin.

What is the standard diameter of cam lock connectors in JYSK furniture? The standard industry size for carcases and drawers is almost universally 15 mm in diameter. The depth or height generally varies between 12 mm and 14 mm, depending on the thickness of the chipboard used.

Can I replace plastic carcase connectors with metal ones? Yes, provided the hole pattern and spacing match. Upgrading to die-cast zinc significantly increases the strength of the joint. For surface-mounted brackets, replacement is straightforward, as screws can simply be fitted in the existing positions.

Which screws do I need for screw-on carcase connectors? Use standard countersunk chipboard screws. For standard 16 mm panels, screws sized 3.5 mm x 15 mm or 4 mm x 15 mm are ideal, as they provide sufficient thread engagement without breaking through the exterior face.

Are replacement locking mechanisms available for office furniture? Yes, cylinder locks for filing cabinets and mobile pedestals follow standardised dimensions. When repairing the carcase, the lock can be replaced at the same time. Pay attention to the backset (distance from keyhole to door edge) and cylinder diameter.
