Frequently Asked Questions
FAQ – Quick Answers
What is the most common pitch dimension?
40×40 mm (NNK® ISP 40) is the most widely used standard in mechanical engineering – good balance of stiffness, weight and accessories availability.
What is the difference between T-groove and C-groove?
T-grooves are fully open – T-nuts can be inserted at any position and at any time. Ideal for flexible constructions. C-grooves are laterally closed, absorb higher transverse forces and allow concealed assembly. Recommended for linear guides and high mechanical loads.
Which groove width fits which pitch dimension?
5 mm groove: 20–25 mm pitch. 6 mm groove: 30 mm pitch. 8 mm groove: 40–45 mm pitch (standard). 10 mm groove: 50 mm pitch upwards to 160 mm heavy duty.
Sind Nutbreiten zwischen verschiedenen Manufacturern kompatibel?
Ja, sofern das Rastermaß identisch ist. NNK® ISP-Profile haben exakt dieselben Nutgeometrien wie item® – alle item® Nutensteine passen direkt. NNK® BSP-Profile sind kompatibel zu Bosch Rexroth®. Nutensteine unterschiedlicher Nutbreiten sind nicht austauschbar.
Was ist eine V-Nut?
A V-groove (also decorative groove) is a 45° chamfer in the profile edge with no connection function, but enables optically clean mitre joints without visible screw heads (internal screwing). Typical in exhibition construction and interior fit-out.
