The Hettich Connecting Screw for 5mm Fitting is a short, coarse-thread fastener designed to mount European cabinet fittings into the 5mm line-bore holes of 32mm system cabinets. It is the right screw when installing European cup hinges, drawer slides, shelf hardware, and other line-bored fittings where hardware manufacturers specify a 5mm connecting screw.
In 32mm system cabinetry, a line of 5mm holes bored at 32mm intervals along the cabinet side panel provides the mounting points for hinges, drawer slides, and shelf hardware. This connecting screw threads directly into those holes to secure the hardware mounting plates flush against the panel face. It replaces the need for a separate pilot hole or anchor and is sized to seat cleanly against standard European hardware mounting flanges.
The screw is steel with a zinc finish, suited to dry indoor cabinet installation. Zinc provides adequate protection against the light handling and shop-environment moisture typical of an interior cabinetry application. For installations inside enclosed cabinet boxes or in climate-controlled shop environments, the zinc finish performs reliably across the service life of the hardware.
Cabinet shops and installers working with European frameless cabinetry are the primary buyers. If the hardware on the bench is a European cup hinge, an undermount drawer slide, or a shelf-pin fitting with a 5mm mounting hole, this is the connecting screw the manufacturer's instructions are calling for. It is also useful for replacement fastening when original mounting screws are missing from a hardware package.
It is designed for 32mm system cabinetry, where 5mm holes are line-bored at 32mm spacing along the cabinet panel to accept European-style hardware fittings.
Most European cup hinges, drawer slides, and shelf fittings from major hardware manufacturers use a standard 5mm mounting hole. This screw is compatible with any fitting that specifies a 5mm connecting screw, regardless of brand.
Yes. The coarse thread is designed for the engineered wood panel substrates most common in European frameless cabinetry, including particleboard, MDF, and melamine-faced panels.
Yes. The zinc finish is rated for indoor, dry environments. It is not intended for exterior or high-humidity applications.
When the hardware calls for a 5mm connecting screw and the panel is line-bored to 32mm system spec, this Hettich screw delivers a direct, confident fit without improvising with a substitute fastener.
