Halfnuts

Single wire lightweight nuts that increase your protection options. Halfnuts excel in shallow placements, pin scars and situations where every gram counts.

Shape provides additional protection options and the reduced width aids stability in shallow placements.

Similarly, to the Wallnuts, sizes 1–4 are made of a harder alloy to prevent shearing and size 5–7 are made of a softer alloy to improve bite.

Sizes 1–2 are rated at 4kN and 3–7 are rated to 6kN.

The 1-7 set is 47% lighter than the equivalent Wallnut set.

The size 7 features scooped faces to save weight.

The single cable reduces weight.

They have the same taper angles and side profile as DMM’s tried and tested Wallnuts.

Colour matched shrink tube for easy identification.
