Product Details

Torx Drive: High Torque & Efficiency

⭐ Key Feature Our Torx drive features a patented six-point star recess for even torque distribution, withstanding 50N·m high torque to eliminate cam-out and prevent fastener/tool damage — ideal for vibration-prone automotive engines and industrial pumps.

Its self-centering design cuts tool alignment time by 40% for automated lines and works with torque-controlled tools, ensuring repeatable precision for quality-critical industries.

Where These Machine Screws Actually Work

Machine teeth screws are widely used in scenarios where there are clear requirements for structural stability and assembly accuracy. The details are as follows:

General Mechanical Equipment Manufacturing

Used for the fixation of the frame, transmission components and ancillary devices of various machine tools, pumps, valves, and compressors. Mechanical screws can withstand the continuous loads and vibrations during equipment operation, preventing component loosening that leads to a decrease in processing accuracy.

Automated Production Lines

Assembly of components such as conveyor belt brackets, motor mounting bases, sensor mounting plates, etc., that are suitable for the assembly line. Especially applicable for the fastening of key parts such as the joint bases and grasping fixtures of industrial robots.

Precision Instrument Housing Fixation

Used for connecting the housings of laboratory testing equipment and measuring instruments with their internal components. Through precise screwing, it can prevent damage to the precise components inside the instrument due to excessive tightening.

Medical Device Manufacturing

Fastening of precision components in diagnostic equipment and surgical instrument housings, meeting the strict stability and hygiene requirements of medical industry standards.

Frequently Asked Questions

Q What makes Torx drive screws better than Phillips or slotted screws?

Torx drive screws feature a six-point star recess that distributes torque evenly across all six contact points, eliminating cam-out — the common problem where a driver slips out under high torque. This design allows up to 50N·m torque application without damaging the fastener or tool, making them significantly more reliable in high-torque and vibration-prone environments such as automotive engines and industrial pumps.

Q What customization options are available for machine screws?

We offer extensive customization including thread sizes from M1.6 to M18 (standard, fine, and coarse pitches), lengths from 3mm to 120mm, and tight tolerances of ±0.02mm. Head styles include reinforced, stepped shanks, and countersunk profiles. Materials available are 304/316 stainless steel, 4140 alloy steel, and C36000 brass. Surface treatments include zinc plating, nickel plating, black oxide, and PTFE coating, all RoHS-compliant.

Q Are your fasteners suitable for medical device manufacturing?

Yes. We supply 316 stainless steel fasteners that meet ISO 13485 biocompatibility requirements. These are specifically designed for use in diagnostic equipment and surgical instrument housings, providing the precise low-torque fit and strict hygiene standards required by the medical industry. Our quality assurance process includes rigorous dimensional and material testing.

Q What quality testing do your fasteners undergo before delivery?

Every batch undergoes comprehensive testing: laser dimension verification at ±0.01mm precision, tensile and yield strength testing, Class 6H thread gauge inspection, ASTM B117 salt spray testing (12–150 hours), and vibration testing from 10 to 2000Hz. Raw materials are certified and ultrasonic-tested. All fasteners are manufactured with cold-forged heads (100–200 tons) and cold-rolled threads, achieving 20% higher tensile strength than cut threads. Zero-defect delivery is guaranteed.

Q How long does it take to receive custom samples?

Custom sample delivery typically takes 10 to 30 days depending on the complexity of the design and material requirements. We specialize in non-standard designs including titanium and Inconel alloys for extreme-condition applications. Our engineering team provides full support from material selection and torque calculation through to on-site guidance, ensuring your custom fastener meets all performance requirements before mass production.

Q Can these machine screws withstand harsh industrial environments?

Absolutely. Our fasteners are engineered for demanding conditions: heavy machinery applications withstand 800MPa dynamic loads and 5–500Hz vibrations; automotive and aerospace versions resist -40°C to 150°C thermal cycling and road salt corrosion to OEM standards; electronics and robotics variants in M1.6–M3 brass or stainless steel maintain conductivity in compact assemblies. Surface treatments such as PTFE coating extend the operating range to -40°C~260°C.
