NEIKO 10056A 1/4-Inch, 3/8-Inch & 1/2-Inch Drive XZN Triple Square Spline Bit Socket Set | 10 Piece Set | Cr-V Sockets and S2 Steel Bits




  • [VERSATILE]: This fastener bit set features 10 metric bits with the 3 largest sizes being tamperproof. Triple-square spline sockets are ideal for use with tamperproof lug nuts, cylinder head bolts, and other engine bolts.
  • [DESIGN]: This kit can convert standard square drives to triple square bits and is designed to eliminate camout and recess fallaway with elliptically based geometry and vertical sidewalls.
  • [PREMIUM QUALITY]: High-strength chrome vanadium steel sockets provide superior torque for greater turning power with mirror chrome finish for corrosion resistance and S2 alloy steel bits reduce wear-outs and ensure longevity and the tamperproof bits are made of CrV for extra strength.
  • [PRECISION]: Precisely machined bit tips ensure accurate size with a 0° drive angle that eliminates radial force preventing fastener recesses and gives access to nuts and bolts on European and Japanese cars and trucks.
  • [INCLUDES]: Set includes 1/4" drive (4mm, 5mm, 6mm), 3/8" drive (8mm, 9mm, 10mm, 12mm, tamperproof 14mm) and 1/2" drive (tamperproof 16mm and tamperproof 18mm).

Mechanics Tool Set for European Cars
The Neiko XZN Triple Square Spline Bit Socket Set is an ideal toolset for mechanics using manual torque tools on European automotive and motorcycle engines, where XZN/triple square fasteners are common.
12-stared XZN/triple square fasteners are often used in high torque automotive applications such as cylinder head bolts and drive train components. Here the many angles of the corresponding bit sockets can generate the increased torque needed.
Each of the 10 metric bits in this set is encased in its own universally oriented drive socket--either 1/4-inch, 3/8-inch, or 1/2-inch--to increase potential torque and limit bit stress. Bits are forged of heat-treated S2 steel alloy for superior hardness, reducing wear-outs and ensuring longevity, while each bit socket is chrome plated to prevent rusting and corrosion. Bit sockets meet or exceed ANSI standards.
