XT1201 set of 6 spanner. Dimensional range: 6x7; 8h9; 10h11; 12h13; 14h15; 16h17 mm. Circular structure of the working part can evenly distribute the load at the time of application of the force, which significantly reduces the risk of "lick" the brink of the angle. The reliability and durability of the tool provides a producing key material chrome-vanadium steel. This causes a very high performance characteristics: increased resistance to mechanical stress, corrosion resistance and hardness. In addition, this alloyed steel has a favorable modulus of elasticity and convenient form of a special key and flexural provide optimum conditions for the force application even in places where a conventional spanner will be useless. The set comes in a carrying case with pockets for each key. Properties High-alloy steel with high performance (chromium-vanadium); The set comes in a handy carrying case with pockets displace for each size;
