    Key Features

    Our self-tapping screws are crafted from food-grade 304 stainless steel and treated to achieve metric Grade 12.9 ultra-high strength, overcoming the traditional hardness limitations of standard stainless steel. Featuring a countersunk Phillips head design, these screws can be installed flush with the workpiece surface for a zero-profile finish, making them ideal for precision electronics and architectural decoration. We have optimized the thread geometry for different substrates (metal, wood) to ensure low-torque driving with high-torque clamping, effectively preventing stripping. As a superior alternative to standard Tek screws, these fasteners perform exceptionally well in thin sheet metal connections, providing an intelligent fastening solution that balances aesthetics with high load-bearing capacity.

    Precision Manufacturing Process

    From wire rod to finished product, we strictly adhere to multiple international standards including ISO, DIN, ANSI, and GB. Utilizing multi-station cold forging technology, we ensure shank diameter tolerances are controlled within microns. Threads are formed through a precision thread rolling process to enhance fastening force. For non-standard requirements, we employ optical imaging sorters to reject minute defects like head cracks. In post-treatment, we offer a wide range of surface finishing options: from conventional zinc plating and nickel plating to highly corrosion-resistant Hot-Dip Galvanizing (H.D.G.), as well as decorative polishing and black anodizing. We even provide food-grade passivation treatment, ensuring every screw has a prolonged fatigue life in demanding environments.

    Transparency & Customization

    As a source factory, we are committed to breaking down the information barriers of traditional trade. From mill certificates for raw materials to hardness grades (covering Grade 4.8 to Grade 12.9, as well as A2-70 and A4-80 marine-grade stainless steel), all test data is traceable. We support full-chain customization: dimensionally, we can adjust thread length and head thickness according to drawings; functionally, we can combine processes like sandblasting, electrophoretic coating (e-coating) , or chrome plating. Whether you need British Standard (BS) fasteners or require a special colored anodized finish, we offer small-batch sampling. This ensures that when you purchase fasteners from us, you not only receive high-quality products but also full transparency and control over the entire process, from material selection to packaging.

    Nylon Insert Design

    Nylon Insert Locking Design for Superior Vibration Resistance

    Manufactured to DIN 985 and ISO 7040 standards, the core design features a nylon insert that creates elastic clamping force on the bolt threads when tightened. This continuous grip effectively prevents loosening under vibration and alternating loads, ensuring reliable locking performance. The temperature-resistant nylon insert resists wear and aging, maintaining excellent anti-loosening properties even in high-vibration applications like automotive and industrial machinery for enhanced safety.
    Easy Installation

    Standard Design & Easy Installation for Versatile Bulk Assembly

    With a standard hex shape, these nuts install just like regular nuts using standard wrenches or torque tools, eliminating the need for additional lock washers or thread-locking adhesives to simplify assembly. Widely applicable in automotive, machinery manufacturing, construction and general assembly, they are ideal for engineering procurement, wholesale and factory bulk supply with complete specifications and stable stock.

    Frequently Asked Questions

    What are the main advantages of Nylon Insert Lock Nuts?
    They provide superior vibration resistance compared to standard nuts. The nylon insert creates friction against the bolt threads, preventing accidental loosening without the need for additional lock washers.
    Do your products meet international standards like DIN 985?
    Yes, our lock nuts are manufactured strictly according to DIN 985 and ISO 7040 standards, ensuring global compatibility and reliable mechanical performance.
    Which materials are available for different environments?
    We offer 304 and 316 stainless steel for high-corrosion environments (like marine or chemical plants) and Grade 8/10 carbon steel with galvanized finishes for heavy-duty industrial and automotive applications.
    How does the nylon insert prevent loosening?
    When the nut is tightened, the bolt threads compress the nylon insert. This creates a constant elastic clamping force that grips the threads, resisting rotation caused by vibration.
    Can I request customized sizes or surface treatments?
    Absolutely. We offer flexible customization for head shapes, special materials, extra-long specifications, and various surface treatment colors to meet your specific engineering requirements.
    Are these nuts suitable for high-vibration automotive chassis?
    Yes, they are widely used in automotive chassis, machinery, and construction due to their ability to maintain locking integrity under alternating loads and high-frequency vibrations.
