Exhibits
Tool-set development begins by considering the target customer, the customer's industry or field of interest, and specific requirements before the R&D team enters the design process. For ratchet design, the company explains a mechanism that moves in only one direction with a fixed swing amplitude, using a spring-loaded tapered pawl and asymmetrically shaped gear teeth. When the gear rotates in the intended direction, the teeth move past the pawl with a clicking sound; when rotation reverses, the pawl engages the teeth and locks the gear, producing torque. In custom metal-part development, production cost is evaluated through total processing time and machine-depreciation cost, and the R&D team looks for ways to reduce process complexity and overall processing time without sacrificing quality or function. The company's named supply range includes Impact Socket & Impact Socket Bit and Automotive Repair Tools, alongside socket tool kits, air chisels, tube tools, and other automotive tools. Its spline socket design is compatible with common fasteners including SAE, Metric, Hex, 6 Point, and 12 Point, and is also described for SAE and metric 6, 8, and 12 point hex, e(star), square, splined, and damaged heads (25%). Applications listed for the spline sockets include tamper-proof lug nuts, cylinder head bolts, and engine bolts, giving the socket family a defined automotive and mechanical fastening role. The sockets use Taiwan-made Chrome Vanadium (CR-V) steel tempered with TIEN-I INDUSTRIAL CO., LTD.'s proprietary heat-treatment process, while a Full Polish Nickel Chrome Finish is used for durability and corrosion resistance. Socket geometry is designed to grip the flat sides of a fastener head instead of the corners to help prevent round-off, and the product is stated to meet or exceed ANSI, DIN, and ISO performance standards. The spline-socket range includes 1/4" Drive, 3/8" Drive, and 1/2" Drive families; examples include QCR29204 at 4 mm and 5/32", QCR39206 at 6 mm and 1/4", and QCR49208 at 8 mm and 5/16". Within the 1/2" Drive family, the listed range extends through models such as QCR49227 at 27 mm and 1-1/16", QCR49230 at 30 mm and 1-3/16", and QCR49232 at 32 mm and 1-1/4". High Torque Strength is specified as meeting at least 1.2 times the ANSI test torque standard, verified by a single-cycle test that applies torque to a specified value without failure or permanent deformation. Other socket details include fully stepped shoulders for access to tight cavities, large permanently roller-stamped markings on the curved face, and surface options ranging from polish to mat, dark to gray, and additional colors. Grooves, color rings, and a knurled base section are available as appearance and handling features, while material guidance distinguishes Cr-V steel for hand sockets from CR-MO for pneumatic sockets. CR-MO is described as having stronger toughness and shock resistance for use with air and electric guns, whereas CR-V has higher hardness but can have reduced service life in shock-resistant use environments. For products not listed in the catalog, TIEN-I INDUSTRIAL CO., LTD. accepts related drawings or samples and product-sales information as references, supporting its OEM/ODM and customized tool-development process. For both impact sockets and chrome sockets, the company notes that popular sizes differ by sales territory and that different countries can require different size selections. Product catalogs are made available for download, providing another support route for customers reviewing the company's hand-tool range.
