UJEN: Your Trusted International Partner for Precision Knob Fasteners and Mechanical Components

UJEN, a Taiwan-based manufacturer of handle screws, knob fasteners, and clamping components, provides a one-stop integrated manufacturing solution that accelerates time-to-market while maintaining precision, quality, and cost efficiency.


In today’s competitive industrial landscape, shorter development cycles and complex supply chains demand a partner that integrates design, tooling, and production under one roof. UJEN, a Taiwan-based manufacturer of handle screws, knob fasteners, and clamping components, provides a one-stop integrated manufacturing solution that accelerates time-to-market while maintaining precision, quality, and cost efficiency.

Facing challenges in sourcing high-quality fastening components?

When sourcing handle screws, knob screws, spring plungers, and adjustable handles, buyers often face budget, MOQ, and customization limits across global catalogs.

  • Is MISUMI perceived as costlier with limited customization windows?
  • Are Elesa+Ganter products elegant but priced at a premium due to brand positioning?
  • Is KIPP sometimes too rigid in process to accommodate rapid engineering changes?
  • Does Carr Lane require higher MOQs with less flexibility for early validation runs?

UJEN provides a pragmatic alternative—cost-effective, responsive, and adaptable to fast-paced OEM/ODM programs.
