    Standard Length Combination Anti-Slip Wrench Set 12 Pieces Set

    • Precision machined for a perfect fit on all fasteners, giving you maximum torque without slippage
    • A 12-point opening doubles the access angles of a 6-point. To prevent round-off, it contacts and applies force to the flat sides of fastener heads rather than the corners.
