The TengTools 1479MMJ is a professional 13-piece hex key set. The keys are manufactured from durable chrome vanadium steel with a corrosion-resistant black oxide finish. The long arm features a ball point hex profile, allowing use at angles of up to 25°, ideal for accessing fasteners in confined spaces. The short arm has a straight hex profile, providing maximum grip when applying higher torque. The set includes sizes from 2 mm to 19 mm, including 7 mm, commonly used in vehicle maintenance such as brake caliper removal. All keys have a hardness rating of 48–52 HRC. The set is supplied in a compact, durable plastic holder with clearly marked sizes. Keys are released by twisting them out of the holder.
