JLHY provides drawing-based OEM and custom screw manufacturing for importers, distributors, industrial users and private-label brands. We review the application, mating materials, installation method and commercial requirements before confirming a workable specification.
Custom options include head geometry, drive recess, thread profile, point design, material and grade, heat treatment, washer assembly, corrosion-resistant coating, color and packaging. Send a drawing, sample or specification with estimated quantity and target market so our team can evaluate tooling, tolerances, testing and production lead time.
