Our factory specializes in standardized and customized Self Tapping Screw solutions, targeting industrial component manufacturers, hardware wholesalers, machinery assembly factories, and electronic processing plants. Different from ordinary fasteners on the market, our Self Tapping Screw adopts an optimized thread tooth design that can form complete internal threads on metal and plastic substrates without pre-drilling, greatly cutting assembly labor costs. We support full parameter customization to match unique fixture demands across different production lines, delivering stable fastening performance under long-term vibration working conditions.
Every Self Tapping Screw undergoes precision thread rolling treatment. Sharp, uniform thread teeth extrude smooth inner threads on thin metal sheets, engineering plastics, and composite plates, preventing cracking and slipping during fastening. Thread hardness is strictly controlled to guarantee repeatable disassembly without thread failure.
We supply two mainstream raw material options for our Self Tapping Screw line:
Available surface finishes: zinc plating, black oxide, Ruspert coating, blue anodizing, and zinc-aluminum coating. Each treatment process passes rigorous neutral salt spray testing to substantially extend the operating life of the Self Tapping Screw.
Our complete range of Self Tapping Screw configurations covers mainstream head profiles: pan head, countersunk head, wafer head, and serrated flange head. Drive systems include standard Phillips and precision Torx drives, catering to both high-speed automated installation and anti-tamper security demands. Tooling integration can be optimized directly to speed up production lines.
As a direct manufacturing source, we accept custom size modifications for every Self Tapping Screw, including custom thread pitches, shoulder dimensions, lengths, and head diameters. Customized head markings, drive configurations, and private-label packaging can be provided for wholesale distributors.

The versatile Self Tapping Screw is widely adopted across multiple light industrial manufacturing sectors:
Case Reference: We maintain long-term partnerships with hardware distributors and machinery builders across Southeast Asia and Europe, delivering millions of standard Self Tapping Screw units monthly. All bulk batches undergo strict third-party dimension and hardness verification prior to dispatch.
Factory-direct sourcing eliminates intermediary markups, reducing unit costs for bulk Self Tapping Screw orders by 15% to 25% compared to trading companies. Our monthly capacity of over 10 million units guarantees stable delivery for framework orders. Comprehensive dimensional, tensile, and salt spray test certificates accompany every batch for fast international customs clearance.
If you require a formal quotation, custom CAD drawing validation, or product samples for testing, please send us your project requirements. Kindly specify your required screw sizes, material grade, protective finish, and estimated batch volume. Our technical sales engineers will deliver a comprehensive proposal and official inspection parameters within 24 business hours.
Yes. With precision thread rolling and case-hardened threads, our screws can smoothly cut or form mating threads into sheet metal, structural plastics, and composite materials directly.
304 stainless steel offers outstanding natural corrosion resistance, making it suitable for outdoor, damp, or washdown environments. Carbon steel provides higher surface hardness and mechanical tensile strength, making it ideal for cost-efficient indoor machinery and standard industrial assemblies.
For harsh or outdoor environments, we recommend Ruspert or zinc-aluminum coatings, which can withstand over 500 to 1,000 hours of neutral salt spray testing without red rust.
Standard off-the-shelf items are dispatched within 3 business days. Custom configurations (including custom head geometry, special drive types, or tailored thread pitches) generally take 7 to 15 business days following drawing sign-off.
Yes. Each production lot comes complete with a Certificate of Analysis (COA), dimensional inspection reports, and salt spray test certificates to ensure compliance with international quality standards.
Yes, we provide complimentary sample batches for standard models so your engineering team can test fitment and pull-out strength. Customers simply arrange or cover the shipping cost.
