When your project requires fasteners that are not available off-the-shelf, JLHY's custom OEM screw service delivers. We work with engineering teams, procurement specialists, and product designers to produce bespoke fasteners to your exact drawings, samples, or technical specifications — from a single prototype run to high-volume production with full quality documentation.

Our engineering team can reverse-engineer samples, advise on material selection, suggest optimal head styles and drive types for your assembly process, and recommend coatings that balance cost against performance requirements. Our capabilities span custom thread forms, non-standard head geometries, specialized points, and unique drive configurations.

JLHY's custom fastener capabilities cover carbon steel, alloy steel, stainless steel (A2, A4, 410, 430), brass, aluminium, and specialty alloys. Surface treatments include zinc plating, hot-dip galvanising, dacromet, phosphating, nickel plating, and custom colours. We manufacture to DIN, ISO, ANSI, JIS, and proprietary standards.

We serve automotive, electronics, HVAC, medical devices, furniture, sporting equipment, and heavy machinery industries. Every custom order is handled with strict confidentiality. Upload your drawings to our RFQ system or contact our OEM team directly to discuss your project requirements.
