MOQ: 1 pc.
Fast delivery:15days.
Cost-effective:20% ~40% cost savings.
Ultra Compact Size:Diameters as small as 5mm,enabling integration into space-limited designs.
Custom Services:Self-reversing screws and nuts manufactured according to your specifications and drawings.
Design & Optimization Services:We assist customers in designing self-reversing screws and optimizing their current designs to achieve better performance and reliability.


Raw Material Control
We purchase raw materials only from qualified high-quality suppliers.Each batch of materials has complete material certification,material test report and quality inspection certificate.


Professional Testing
We use professional testing equipment and tools to strictly inspect product size, appearance and performance.
100% Double Inspection
Every self-reversing screw goes through 100% inspection.First,the factory conducts initial inspection;then the export department does secondary inspection.Products are delivered only after both inspections are passed and results are confirmed correct.

Operation & Function Test Videos
We will send customers operation videos of self-reversing screws,pawl and nuts,together with function test videos and pictures.
Product & Packaging Details Confirmation
We will send customers detailed product pictures and all packaging pictures before shipment to ensure all details meet customer requirements.


Our mini reciprocating screws are widely used in:
Industrial Robots:Reliable actuation for repetitive tasks with high accuracy.
Tethered Drones:Stable and controlled deployment/retrieval mechanisms.
Portable Hand Winches:Lightweight and efficient force transmission for compact lifting systems.
Automated Reciprocating Wire Guidance:Precise linear motion in winding and dispensing machinery.
Carbon Fiber & Packaging Band Spooling:Smooth,consistent tension control for material winding.
LMT operates as more than a component supplier.We engage as a technical partner,providing expertise in miniature self-reversing screw design.Our dedicated focus on reciprocating screw technology ensures we deliver solutions that meet complex performance criteria for our clients' most challenging applications.Contact us to discuss your project requirements and receive expert support for your motion control needs.
