## Background

Tien-I was founded in 2004 in Taichung, Taiwan — a city widely recognized as the historic center of Taiwan's hand tool industry, which traces its manufacturing roots back to technology transfer from Japan and the United States in the 1960s. Larry Lee and Shaio-Pao, together with ten industry partners, built Tien-I with the goal of becoming more than a parts supplier: a long-term manufacturing partner for global tool brands.

Over more than two decades, the company has grown its catalog from basic hand tools to a broad line of hand and power tools — including socket tool kits, impact sockets, air chisels, tube tools, and automotive repair tools — while maintaining 100% manufacturing in Taiwan. Tien-I has been recognized with the Taiwan Excellence Award (2016). (See "Target Clients / Ideal Customers" below for the industries and markets Tien-I serves.)

## Featured Product Lines

### Hand Tools (Hand Tool Sockets)

Hand tool sockets are one of Tien-I's founding and core product categories. Tien-I manufactures a full range of hand-driven sockets — including 6-point, 12-point, star (E-type), spline, triangle, universal joint, super lock, low-profile, and extra-deep sockets — built from Cr-V (chromium-vanadium) steel for durability under manual torque. The line is supported by a complete set of accessories, including ratchet handles, drive handles, extension bars, and adapters, allowing buyers to source a complete hand tool socket system from a single manufacturer.

### Impact Sockets

Tien-I is a leading manufacturer and supplier of impact sockets — tools engineered specifically for use with powered impact wrenches, delivering the high torque needed to securely fasten bolts and nuts. These sockets are compatible with air-powered, electric, and hydraulic impact wrenches, making them a core product for professional automotive, industrial, and heavy-equipment users.

Key features of Tien-I's impact sockets:

- **Wide Size Range** — available in metric (6 mm–95 mm) and imperial (7/16"–3-1/2") sizes, covering most professional application needs.
- **High-Quality Material** — made from durable Taiwan-sourced Cr-Mo (chromium-molybdenum) steel, heat-treated to meet DIN or ANSI standards.
- **Comprehensive Accessories** — extension bars, adapter drives, and universal joints available for added versatility.
- **Enhanced Safety Design** — locking pin-and-ring design keeps the socket securely seated during high-torque applications.
- **Easy Identification** — each socket is clearly marked with its size for fast, error-free tool selection.
