Lamello® Hex key, SW 4 mm, length 144 x 29 mm (Item No. 271959L)

Lamello® Hex key SW 4 mm (144 x 29 mm) – Extra-long special version for the deepest access holes

The original Lamello® hexagonal pin spanner, size 4 mm, in the extra-long special version measuring 144 x 29 mm (item no. 271959L) is the ultimate precision tool for the most challenging installation situations when securing Lamello Clamex connecting fittings (such as Clamex P-14, Clamex P-10 and Clamex S-18).

With an impressive blade length of 144 mm, this special spanner effortlessly handles even solid material thicknesses, oversized cabinet depths or concealed partition walls. It guides the user accurately to deep-set Ø 6 mm access holes and, thanks to high-quality, hardened tool steel, ensures maximum, torsion-free power transmission.

Applications and how it works

The extra-long hex key offers maximum reach in professional interior fit-out work:

Application Function & Benefits
Extremely deep drill holes The 144 mm length effortlessly reaches fittings that remain out of reach with standard tools.
Torsion-resistant strength Dimensionally stable special steel prevents the long leg from bending under high torque.
Compact short shank The short 29 mm leg allows the tool to be positioned in confined spaces and in the corner of the cabinet.

Key advantages of the Lamello hexagonal pin key 144x29 mm:

  • Maximum reach: a 144 mm leg length copes with even the thickest wall thicknesses and special constructions.
  • Precise SW 4 fit: Engages positively and without play in the internal hexagon of the Clamex locking lever.
  • High-quality tool steel: Extremely resistant to bending and wear for heavy-duty, continuous use in the workshop.
  • Efficient assembly: Eliminates the need for cumbersome dismantling steps when working with deeply recessed connection points.
  • Genuine Lamello quality: Perfectly matched to the tolerances of the P-System and Clamex fittings.
