Trapezoidal Screw Right and Left Hand
Suzhou Maitu boasts 12 years of expertise in the production of quality Trapezoidal Screw Right and Left Hand. Trapezoidal lead screws serve as essential mechanical components, enabling the conversion of rotational motion into precise linear movement.Our 30°trapezoidal screws, in both left-hand and right-hand configurations, are engineered to match customers' specific design requirements for pitch, lead, and diameter, providing stubborn screw performance for complex motion systems.
What characterizes quality Trapezoidal Screw Right and Left Hand from Maitu most distinctly is the 30-degree thread angle. In contrast to the sharp-edged V-threads designed for fastening, trapezoidal screws boast a 30° included flank angle, with their root and crest running parallel to the screw’s axis. This unique geometric design—formalized in international standards including ISO metric trapezoidal screws—is tailored specifically for transmitting power and supporting loads. The designation "trapezoidal" refers to the trapezoidal contour of the thread when cut in cross-section.
By employing one left-hand and one right-hand screw in a single assembly, a single rotational input can drive two nuts to move towards or away from each other simultaneously or by controlling system . This specific design is engineered for applications requiring precise opening, closing, or centering actions, such as in clamps, vises, sliding doors, and precision stage platforms.
However, the self-locking capability, a key inherent characteristic of Trapezoidal Screw Right and Left Hand, is equally effective in both left-hand and right-hand designs. This non-reversibility remains a critical safety feature, ensuring stable and secure positioning in vertical or inclined orientations, regardless of the thread direction.
Product Features
① Dual Rotation Direction Design: Integrated right-hand and left-hand thread configurations, which can drive two nuts to move towards or away from each other simultaneously with a single rotational input, perfectly matching the precise opening, closing, and centering needs of industrial equipment (e.g., clamps, precision stage platforms).
② Standard 30° Thread Angle Advantage: Adopts ISO metric standard 30° included flank angle, with thread root and crest parallel to the screw axis—this trapezoidal cross-section design enhances load-bearing capacity and power transmission efficiency, superior to sharp-edged V-threads for fastening scenarios.
③ Reliable Self-Locking Safety Performance: Inherent self-locking capability in both right-hand and left-hand designs, ensuring non-reversibility and stable positioning in vertical or inclined applications, effectively avoiding safety risks caused by accidental displacement.
④ High Precision Linear Transmission: Through advanced thread rolling and CNC machining, thread pitch, lead, and dimension accuracy are strictly controlled, ensuring precise conversion of rotational motion to linear motion, suitable for high-precision motion systems.
⑤ Wide Specification Compatibility: Covers standard major diameters (8mm-50mm) and leads (1.5mm-8mm), with left-hand/right-hand configurations available for all specifications, directly matching the production parameters of most industrial equipment.
Customization Services
① Rotation Direction & Thread Customization: Beyond standard right-hand/left-hand configurations, we support customized thread direction combinations (e.g., dual left-hand, segmented right-left thread) and non-standard thread parameters (custom pitch, lead, start number) according to customers’ equipment assembly requirements.
② Dimension & End Machining Customization: Based on customers’ drawings, we customize major diameter, length, and end machining (threaded ends, chamfering, keyway, drilling) to ensure perfect fit with existing equipment, reducing installation modification costs.
③ Material Matching Customization: According to application scenarios (load, corrosion resistance, temperature), we provide customized material selection (carbon steel, stainless steel, brass) and surface treatment (zinc plating, nickel plating, nitriding) to optimize product durability and service life.
④ Assembly Matching Customization: We customize matching nuts (brass, engineering plastic, bronze) and accessories according to the left/right-hand screw specifications, ensuring seamless fit, reducing wear, and improving the overall stability of the transmission system.
⑤ Small-Batch & OEM Customization: Support small-batch customization (MOQ 1 PC) with no extra fees, suitable for prototype testing and small-scale production; provide OEM services (custom labeling, packaging, logo printing) to meet global buyers’ branding needs.

FAQs
1. How do you ensure the self-locking performance of left/right-hand trapezoidal screws in vertical load scenarios?
We optimize the thread helix angle and surface finish during Trapezoidal Screw Right and Left Hand production to enhance self-locking reliability; each finished product undergoes strict self-locking performance testing (load-bearing anti-reversal test), and we provide test reports to verify; we can also recommend matching braking accessories for ultra-heavy load scenarios.
2. What is the lead time for customized right/left-hand trapezoidal screws with non-standard dimensions?
For non-standard dimensions with standard materials and surface treatment, the lead time is 7-10 working days; for special thread combinations (e.g., segmented right-left) or special materials (stainless steel, brass), it is 10-15 working days, and we will feedback the production progress.
3. Can you customize a trapezoidal screw with both right-hand and left-hand threads on a single rod (segmented design)?
Yes. We can design and produce segmented right-left thread screws according to your equipment assembly requirements, including custom segment lengths, thread parameters, and end machining; we will first provide a 3D design drawing for your confirmation, then produce samples for test verification before bulk production.
4. Do you provide technical guidance?
Yes. We provide detailed assembly guidelines (including torque requirements, lubrication suggestions) and online technical support; if you encounter assembly difficulties, our technical team can arrange online guidance or on-site support (if needed), helping you avoid assembly errors and extend product service life.
