Leadnuts
Mating nuts for Apex lead screws: flanged for direct mounting, or anti-backlash for zero-clearance positioning.
Leadscrews
Precision lead screws that translate rotary motion into linear motion. Thread-formed, thread-cut, or thread-ground in Carbon Steel, Alloy Steel and Stainless Steel.
Why Apex
Accurate & Precision
Thread-formed, thread-cut, and thread-ground lead screws manufactured to consistent, repeatable tolerances.
All Manufactured In-House
Every tool is made in-house, which keeps lead time for delivery short instead of depending on outside suppliers.
Compact, Quiet, Affordable
Apex lead screw assemblies outperform bulky, noisy, expensive hydraulic or pneumatic actuator systems for linear motion.
Off-The-Shelf Stock
Standard lead screws are kept in stock across a wide range of pitches and sizes, so there's no waiting on a production run for common sizes.
Multiple Thread Profiles
Trapezoidal, ACME, Square, and Metric thread profiles, in Carbon Steel, Alloy Steel (EN8), and Stainless Steel.
Custom Engineering On Request
Custom leadscrews with special end machining, and custom/modified nuts (special bore patterns, materials or integrated components), built to your specification.
Applications
Where Apex products are used
3D printer Z-axis
Leadscrews raise the print bed or gantry layer by layer with fine, repeatable steps.
Operating mechanisms for switchgear
Worm reductions drive motorised isolators; leadscrews rack draw-out breakers in and out.
Leadscrew-driven machine axes
Trapezoidal leadscrews and nuts move cross slides, tables and tailstocks on lathes and milling machines.
Leadscrew linear actuators
How to choose the leadscrew and nut for a motor-driven linear actuator: lead for speed, self-locking for holding, diameter for length and load, and the right nut for accuracy and wear.
Syringe and infusion pumps
Fine-pitch leadscrews with anti-backlash nuts push the syringe plunger at a precise, steady rate.
Lab automation and analysers
Leadscrew drives position pipettes, sample stages and grippers in analysers and lab automation.
