Custom Fasteners Manufacturer

SUNHY supplies drawing-based fasteners for industrial assemblies where a standard catalogue item does not match the required geometry, material, thread or finish. Send the drawing, application conditions and inspection requirements with your RFQ so the manufacturing scope can be reviewed before quotation.

Custom fastener scope

• Bolts, screws, studs, nuts, washers, pins and threaded parts
• Metric and inch threads, including specified thread pitch and tolerance
• Carbon steel, alloy steel and stainless steel grades stated on the drawing
• Standard or drawing-defined surface finish, marking and packaging
• Prototype, replacement and production requirements subject to drawing review

Information required for quotation

Include the part drawing or 3D model, dimensions and tolerances, material grade, thread standard, finish, quantity, inspection plan and required documents. Where a requirement is not specified, SUNHY will identify the open point before production rather than assume a value.

For catalogue products, review the industrial fasteners range. For non-standard nut geometries, see special nuts.
