Neiko 10076A 3/8-Inch Drive Extra Long Allen Hex Bit Socket Set, Metric, 3 mm - 10 mm | S2 And Cr-V Steel, 7-Piece Set

Estas puntas me sirvieron para aflojar tornillos con cabeza para allen, en donde el acceso alrededor del tornillo estaba muy limitado por otras partes de la maquinaria. La entrada "drive" de 3/8" de la punta me sirvió para acoplar una extensión y una "matraca" para aplicar mas palanca o torque a la hora de aflojar el tornillo (de 3/16" que era el que necesitaba quitar).Todo trabajó perfecto.

I work on European cars for a living and Lord knows some bolts are not easy to get a tool on. These long-shank bits do the job perfectly. So far, after half a year in my shop, they have not shown any visible wear or damage and fit the bolt heads tightly, as intended.

I use this set daily as a CNC machine tool technician. I thought they would not hold up all that long in an industrial setting but to my surprise they have taking everything I throw at them. They have no sine of twisting or the ends stripping off and on occasion I have used them with a breaker bar. Would strongly recommend this set.

They seem well made other than one of the Allen shafts was put in crooked. I will give a further review after more use. I work on Excavator drives so it will be a full workout of them.

Just got these works OK It had the Size I needed. Looking forward to comment about quality later date
