In-house decibel, aperture, and parameter inspections.
Tailored material grades, coatings, and dimensions.
Meeting the demands of modern automation, smart grids, and structural engineering
The global fastener industry is transitioning from standard carbon-steel applications to high-performance alloy structures designed to withstand extreme thermal, chemical, and physical stresses. As a key OEM/ODM partner, TorqPro is at the forefront of this evolution, utilizing titanium alloys, aircraft-grade aluminum, and high-tensile chrome steel. Whether for aerospace micro-drives, robotic joints, or food-safe restaurant equipment, our customized screws provide the essential structural holding power that keeps high-performance machinery locked and aligned.
From multi-station cold heading to micro-grinding, we tailor solutions to match your specs
Capable of producing miniature M0.8 to M3 screws with complex drives (Torx, Hexagon, customized tamper-resistant sockets) for thin-profile consumer electronics and high-rpm mechanical components.
Ultra-precise thread rolling machines ensure structural integrity, perfect surface finishes, and zero fiber distortion in the raw material, keeping shear margins high.
Anodizing, zinc-nickel plating (withstanding 1000+ hours salt spray test), PTFE coating, and passivating for extreme harsh environments and marine setups.
Traceable quality check steps assuring micro-scale parameters and extreme durability

Visual sorting and quality verification during robotic assembly runs, preventing defective parts from entering packages.
Employing high-resolution mechanical probes and optical sensors to measure bore diameters and depth alignments.
Automated parameter systems document the performance profile of each batch to support traceability requirements.
Acoustic tests in isolation chambers verify low-noise characteristics (restaurant, medical, and smart-home standards).
Continuous decibel scanning automatically flags noise anomalies, ensuring smooth operation of bearings and gears.
Addressing mechanical stress, corrosion, and precision assembly challenges
Choosing the correct raw alloy defines the ultimate shear resistance and torque handling of fasteners. For applications demanding weight reductions without sacrificing tensile strength—such as aerospace hinges, micro-servos, and lightweight drones—we leverage Grade 5 Titanium (Ti-6Al-4V) and aerospace-grade anodized aluminum. For environments prone to moisture, acidic sanitizing solutions, or marine climates, we implement high-grade 316 Stainless Steel or Chrome Steel alloy variants (such as 6300-series bearing components), providing optimal resistance against galvanic corrosion and pit wear.
In high-rpm engines or vibrating robotic structures, fastener relaxation poses a significant failure risk. We counter this via customized thread profiles and advanced pre-applied thread-locking patches (e.g., Nylok, reactive micro-encapsulated adhesives). Our thread rolling machines operate to Class 6g/6H tolerances, ensuring snug fits that distribute structural loads evenly across the thread geometry, eliminating internal play and stress hot spots.
Different applications demand distinct surface chemistry. Our surface finishing facilities include:
By managing the chemistry in-house, we verify that final coatings comply with global B2B regulatory standards, including RoHS, REACH, and California Prop 65.
In modern industrial design, mechanical parts do not exist in silos. A high-performance digital servo, planetary gearbox, or deep-groove ball bearing requires dedicated micro-screws, spacers, and custom alignment shafts to work reliably. TorqPro’s unique capability to design and manufacture both precision drive systems (motors, controllers, gearboxes) and custom fasteners (cold-headed screws, locating pins, lead screws) allows for turnkey mechanical solutions. This structural synergy ensures lower mechanical loss, noise reductions, and extended operational lifespans for B2B OEMs globally.
Answers to complex design, material validation, and logistics questions
For cold-headed micro screws, we maintain standard tolerances of ±0.05mm. For critical applications requiring micro-precision—such as internal drive shafts, lead screw components, and aerospace fittings—our secondary precision CNC machining and grinding operations can achieve tolerances as tight as ±0.003mm.
High-tensile fasteners (Grade 10.9, 12.9, and above) are susceptible to hydrogen embrittlement post acid-pickling and electroplating. We mitigate this risk by executing a strict de-embrittlement baking process (typically 200°C for 4 to 8 hours depending on dimensions) immediately after plating, ensuring hydrogen gas diffuses out of the metal matrix before it causes micro-cracking.
Every shipment is supported by a comprehensive QA documentation pack, including Material Test Reports (MTRs) detailing alloy chemistry, Salt Spray Test logs for plating verification, Dimension Inspection Sheets (caliper/micrometer/optical projector tests), and certificates of compliance (RoHS, REACH). We also support the PPAP (Production Part Approval Process) Level 3 documentation for automotive-grade components.
Upon receipt of 2D/3D CAD models or physical samples, our engineering team completes feasibility audits within 48 hours. Tooling creation and initial sample prototyping take 10 to 15 business days. Once samples are approved, mass production cycles generally run between 25 and 35 days, depending on batch sizes and coating complexity.
