Overview
An automotive technician working on spline fasteners is the buyer for this NEIKO socket set. The bits use a square shank drive end with a spline pattern and come in a blow mold case.
Two bit lengths let the user reach recessed fasteners and also work in tight spots. Corrosion-resistant chrome finishing helps in a toolbox. The listing gives both eleven pieces in the title and ten in the specs.
Who it's for
Mechanics with spline-head fasteners get matching bits in several metric sizes. Shoppers who need a confirmed drive size for their ratchet should check it, since the listing names only a square shank.
Pros and cons
- Long and short bits
- Chrome finish with corrosion resistance
- Blow mold case included
- Five metric sizes
- Piece count differs between title and specs
- Square drive size not given
- Not for hex or Torx fasteners
- Item weight field unreliable
Performance notes
A spline bit seats in a matching recess and grips more of the head than a plain hex. Longer bits reach deep into recesses while short ones suit tight spaces. Chromium-vanadium steel resists twisting under torque.
