TRUSCO Half Ball Hexagonal Wrench 4.0mm THBR-40 1 piece

Catalog number: THBR-40 Features: ● The short end is processed with a half-ball point to make it easier to approach the hexagonal hole than conventional products. ● The half-ball processing makes it easier to insert and achieves the same level of torque transmission force as conventional products. ● The screw can be turned from a maximum inclination angle of 32°. ● In order to ensure a uniform and high-precision tempering (heat treatment) hardness (HRC 60° ± 1°), a completely non-oxidizing and decarburizing correction quenching method is used in a closed furnace instead of a continuous furnace. ● The ball point can be used to tighten the screw. ● Partially painted so that the size can be identified at a glance by color. ● The special chrome plating surface treatment provides excellent wear resistance and will not rust for a long time.
