Hetai Custom Screws is a premier manufacturer specializing in high-precision, custom-engineered screw manufacturing tailored for demanding global industries. By integrating high-speed multi-station cold heading, thread rolling, and Swiss CNC micro-machining, Hetai delivers tailored fastening solutions that tackle complex geometry, strict tolerances, and high-load mechanical environments.
Custom Screws
Engineered entirely from customer-provided blueprints or functional concepts. Hetai offers complete customization flexibility across thread profiles, head geometries, drive types, point styles, and shoulder configurations to meet application-specific mechanical demands.
Non-Standard Screws
Tailored screw solutions built outside conventional ISO, DIN, ANSI/ASME, or JIS standard dimensions. Designed specifically to solve space constraints, proprietary assemblies, legacy equipment retrofits, and micro-precision requirements where off-the-shelf fasteners fail to perform.
Special-Shaped Screws
Complex-geometry fasteners manufactured through specialized multi-stage cold forming and CNC post-machining. Product portfolio includes eccentric head screws, stepped/multi-diameter shoulder screws, hollow screws, captive screws, dual-thread screws, and anti-tamper security configurations.
Material Versatility: Stainless Steel (304, 316, 410), Carbon Steel, Alloy Steel, Titanium Alloys, Brass, Copper, Aluminum, and High-Temp Alloys.
Precision Tolerances: Micro-machining and precision cold heading capable of tight tolerances down to ±0.005 mm for delicate electronics and aerospace instruments.
Property Classes & Grades: Metric Grades 4.8, 6.8, 8.8, 10.9, 12.9 | Imperial SAE Grades 2, 5, 8 | Case-hardened (surface hardening) for self-tapping / thread-forming screws.
Surface Treatments & Coatings: Advanced corrosion protection including Zinc Plating (Cr3+ trivalent), Zinc-Nickel Alloy, Dacromet, Geomet, Black Oxide, Anodizing, Passivation, and Nylok/PTFE anti-loosening thread-locking patches.
Quality Control & Testing: ISO 9001 & IATF 16949 certified production lines featuring 100% optical sorting (CCD screening), salt spray testing, torque testing, and full material batch traceability.
