Import Bolts — Buy in Bulk from Supplier in Taiwan

Kunhan Co., Ltd. supplies a broad assortment of bolts manufactured in Taiwan, covering hex bolts, socket cap screws, socket set screws, machine screws, tapping screws, self-drilling screws, T bolts, U bolts, and W bolts. The range spans light to heavy-duty industrial applications, with finishes including galvanized and stainless steel options for corrosion resistance. These fasteners serve construction, automotive, machinery, and electronics sectors where reliable joint integrity is critical. The supplier operates from Dongguangyuan Road in Taichung's East District, with an imported supplier tier and harbor trust designation.

Material options centre on carbon steel substrates with surface treatments that extend service life in aggressive environments. Hex bolts follow standard coarse and fine thread patterns; socket cap screws provide recessed drive configurations for flush or countersunk assemblies. Self-drilling and tapping variants reduce pre-drilling requirements, accelerating installation in sheet metal and timber. T, U, and W profiles address specialised structural and framing needs. Typical tensile strength grades for carbon steel hex bolts range from 4.8 to 12.9, though buyers should confirm the specific grade map Kunhan stocks.

Buyers sourcing through this listing should verify thread pitch, length increments, and head dimensions against their engineering drawings. Machine screws suit threaded inserts and tapped holes in precision equipment, while socket set screws secure collars and pulleys without protrusion. Automotive and machinery OEMs represent the core import segments, with construction contractors representing seasonal bulk demand. Packaging and Incoterms are not specified in the source data; confirm carton quantities, palletisation, and whether Kunhan ships FOB Taiwanese ports or offers alternative terms.

Kunhan Co., Ltd. is located at 1f., No.50, Dongguangyuan Road, East District, Taichung 40145, Taiwan.
