Material: stainless steel
Finish: plain
Samples: Free
Standard:Non-standard , drawing or samples
Material: Made from high-quality stainless steel (AISI 304, 316, or 316L), 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 bolts 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.
Special Shapes: We offer a wide range of special shapes to meet your specific needs. Whether you need a custom head shape, a unique bolt body design, or a specific thread profile, our team can work with your sketches or CAD files to create the perfect bolt.
Head Styles: Available in a variety of head styles, including hex, square, pan, cheese, countersunk, binding, shoulder, knurled, thumb, and even custom logo-stamped heads.
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 bolt geometry ensures precision and consistency. A random sample undergoes tensile strength and 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.
