Overview
A triple square spline tip grips the matching XZN fastener head, and a square shank links each bit to a driver. The alloy steel bits are sorted by metric size and cover the range from small to large.
Three shank sizes let the same bits move between a hand tool and an impact driver, which suits automotive work on XZN-headed bolts. The limitation is that the listing gives no case description and no torque rating.
Who it's for
An engine bay or brake job with spline-headed bolts is where a set like this earns its place in the drawer. Shoppers with only standard hex or Torx fasteners will not use these bits and should buy a different set.
Pros and cons
- Covers a wide metric range
- Three square shank sizes
- Works with impact and manual tools
- Alloy steel construction
- Not a wrench despite the label
- Case type not described
- Torque rating unspecified
Performance notes
The spline profile spreads the turning force around the fastener head, which reduces rounding on tight bolts. Compatibility with an impact driver, a manual torque tool and a nut driver means the shank size must match the tool that holds it.
