Backed by some 30 years of expertise in heat treatment, Shun Den Iron Works Co., Ltd. has diversified into hex-key wrenches, aiming to be a world-caliber, top-end supplier of hex-key wrenches.

Driven by End-user Demand

Driven by end-user demand for high-quality hex-key wrenches, it decided to venture into the sector in 2009 after several decades of forging, die casting and stamping work, tapping such seasoned skills and know-how of heat treatment to develop high-quality hex-key wrenches.

It spent over one and half years focusing its R&D on top-end products from Germany and Japan, as well as studying users’ experience in machinery and mold maintenance, and ultimately figured out a solution for the technical dilemma of balancing structural flexibility and surface hardness, which has not been addressed in most wrenches sold in different markets.

It says that wrenches sold in Europe are moderately hard, being rated between 50 and 53 and structurally flexible but prone to wear, compared to those from Japan and Taiwan that are high-HRC-processed, hardness-rated between 56 to 62, though more easily fatigued to be more dangerous to users. To build a better product, it has applied special heat treatment to overcome the problem, hence developing its line of superb quality, professional-grade hex-key wrenches.

Highest Criteria

It claims that each batch of hex-key wrenches is sample-tested according to a full process to ensure the highest structural flexibility, lifespan and wear-resistance.
