Leadnuts

Mating nuts for Apex lead screws: flanged for direct mounting, or anti-backlash for zero-clearance positioning.

Browse Leadnuts

Anti-Backlash Nuts

Zero-clearance nuts that compensate for wear between screw and nut when reversing direction.

Box & Custom Nuts

Rectangular box nuts and custom lead nuts: block nuts that bolt flat to a carriage, and nuts modified or designed around your assembly.

Flange Nuts

Flanged lead nuts for direct bolt-on mounting, in Brass or Stainless Steel.

Nut types

Flange nut: round flange for bolting straight to the moving part. Standard sizes in brass or stainless steel.
Economical flange nut: compact flange nut, best suited to 3D printers.
Triangular flange nut: three-cornered flange for tight mounting spaces.
Rectangular box nut: block nut with tapped holes, bolts flat to a carriage or slide.
Anti-backlash nuts: radial-loaded or axial-loaded, compensating for clearance and wear when the direction reverses.
Custom nuts: modified mounting, integrated parts, special materials such as Delrin.

Standard nuts are made in brass or stainless steel with ACME or Trapezoidal threads, to match Apex leadscrews.
