Description QS50008

The HEX impact bit set QS50008 is a professional tool for workshops that perform work with hexagonal fasteners on modern cars. This set contains 8 bits in sizes from H5 to H19, 78 mm long each, with a 1/2" drive. Made of chrome-molybdenum steel with a black phosphate coating.

The use of short bits in combination with extensions often leads to skewing, stripping of fastener heads, and damage to the fastener. QS50008 completely solves this problem: the 78 mm length allows you to reach recessed bolts without extensions, chrome-molybdenum steel withstands impact loads, and the black phosphate coating protects against corrosion. The set is supplied in a convenient case.

Technical specifications

⚠️ Important: The bits are designed for impact use. Make sure the bolt profile matches HEX before use.
