MOQ depends on the product type, size, material, finish and whether the item is standard or custom-made. For many standard fasteners, bulk orders can start from several thousand pieces per size. Custom fasteners may require a higher MOQ because of tooling and setup costs. Send us your specification and quantity for an exact MOQ and quotation.

Yes. We support custom bolts, nuts, screws, studs and special fasteners based on 2D/3D drawings, PDF files, technical specifications or physical samples. Custom options include dimensions, thread types, head styles, materials, strength grades, surface finishes and packaging.

Common surface finishes include zinc plating, hot-dip galvanizing, black oxide, phosphate, Dacromet, Geomet and zinc-nickel coating. The recommended finish depends on the material, corrosion resistance requirement and application environment. Salt spray requirements can be discussed for specific projects.

Yes. Samples can be provided for product checking, testing and approval before bulk production. For custom fasteners, sample timing depends on whether new tooling or secondary machining is required.

Depending on the product and order requirements, we can provide dimensional inspection reports, material certificates, mechanical test reports, EN 10204 3.1 certificates and PPAP documentation where applicable. Please confirm the required documents before ordering.

Production lead time depends on the product, quantity, material, surface finish and packaging requirements. Standard or stocked products can usually be prepared faster, while custom fasteners and special finishes require additional production time. We confirm the expected production and dispatch date before order confirmation.
