-
Material: Made from high-quality stainless steel (AISI 304 or 316), ensuring excellent corrosion resistance and durability. These materials are ideal for various environments, including outdoor, marine, and industrial settings.
-
Quality Standards: Each batch comes with a 3.1 Material Test Certificate (MTC), confirming compliance with international standards such as ISO, ASTM, and DIN. Additionally, the screws undergo salt-spray testing (ASTM B117) for a minimum of 1,000 hours, ensuring long-term performance.
-
Optional Coatings: Available with electropolishing for enhanced surface finish and corrosion resistance, or PTFE coating for applications requiring low friction or food-grade compliance.
-
Head Styles: Available in a wide range of head styles to meet your specific needs, including pan, cheese, countersunk, binding, shoulder, knurled, thumb, and even custom logo-stamped heads.
-
Slot Design: The slot can be customized in terms of width, depth, and shape. Options include standard, thin, wide, undercut, offset, and safety slots to prevent cam-out. Radiused slots are also available to reduce stress risers in thin-walled materials.
-
Thread Profiles: Choose from machine threads (2A/6g), self-tapping threads (AB, B, BT), wood threads, hi-lo threads, micro threads, left-hand threads, or twin-lead threads. Full-thread, partial-thread, and under-head relief configurations are also available.
-
Dimensions: Available in a broad range of diameters (M1 – M30, #000 – 1") and lengths (1 mm – 250 mm). Custom tolerances can be specified to meet tight engineering requirements.
-
Inspection: 100% optical inspection of the slot geometry ensures precision and consistency. A random sample undergoes torque-to-failure testing to verify strength and reliability.
-
Certificates: Each shipment includes a 3.1 MTC, RoHS/REACH compliance certificates, and salt-spray test results. Additional documentation such as PPAP Level 3, IMDS, and FAI can be provided within 24 hours upon request.
-
Traceability: Color-coded inner bags and barcode labels with your part number, batch QR code, and test coupons ensure full traceability and ease of inventory management.
-
Lead Times: Prototypes can be delivered within 10 days using 3D laser cutting and thread rolling. Production orders for quantities under 50,000 pieces can be completed in 2–3 weeks after receipt of order (ARO).
-
Order Flexibility: Blanket orders with locked pricing for up to 12 months are available, allowing for weekly or monthly call-offs. Vendor-managed inventory (VMI) and dock-to-stock options are also provided to streamline your supply chain.
-
Packaging: Neutral white-label packaging or custom laser-marked heads are available. Export cartons with divider trays are ready for SMT pick-and-place feeders, ensuring compatibility with your assembly line processes.
