Multi-Material Precision Fasteners & Custom Pins

Please provide 2D/3D drawings specifying dimensional tolerances, material grades, and surface treatment requirements to evaluate the manufacturability of custom pins, rivets, or connectors. These components are typically used for positioning, hinging, or fastening in mechanical equipment, requiring precise fit clearance and structural stability after assembly.

The displayed parts include plain shafts, stepped shafts, pinned holes, and irregular connectors, utilizing materials such as stainless steel, copper alloys, and carbon steel. Key machining focuses include controlling outer diameter tolerances, concentricity, and head formation consistency. For complex structures with cross-holes or threaded features, multi-setup clamping is employed to ensure positional accuracy and prevent geometric deviations during mass production.

Equipped with Swiss-type lathes, automatic lathes, and turn-mill composite centers, we support high-precision continuous machining of small-diameter shafts, meeting stringent standards in automotive interior frameworks, agricultural machinery, and rail transit. Backed by an IATF16949 quality management system, we offer surface treatments such as blackening, galvanizing, and passivation. Full-dimensional inspection using CMM and vision measuring instruments ensures compliance with RoHS/REACH environmental regulations.
