56-Piece 1/4" Drive Master Impact Socket Set, Standard SAE and Metric Sockets


  • COMPREHENSIVE SELECTION - This 56-piece 1/4" drive impact socket set includes SAE (5/32"-9/16") and metric (4-15mm) sizes in both shallow and deep versions, plus ratchet handle, extension bars, and universal joint for complete small fastener solutions
  • INDUSTRY-STRONG DURABILITY - Forged from heat-treated chrome vanadium steel with black phosphate coating, these 6-point sockets resist corrosion and wear while withstanding high-torque applications in professional workshop environments
  • PRECISION ENGINEERING - The 6-point socket design maximizes contact surface with fasteners, increasing locking force while preventing corner rounding and reducing wear during precision mechanical work
  • QUICK IDENTIFICATION - Features laser-etched size markings that remain clearly visible in low-light conditions, enabling rapid tool selection and improving workflow efficiency during time-sensitive repairs
  • PROFESSIONAL ORGANIZATION - Comes in custom-molded storage with designated slots and printed size labels, ensuring secure tool arrangement and easy transport to job sites and mobile workshops


Product description

66107-1

  • Laser marking, each with a clear laser size mark, makes it quick and easy to select even in dim light.
  • Customized storage boxes, each with a designated slot, so that the socket does not fall off easily. Sizes are also printed next to each card slot for easy identification.
  • 6-point socket design expands the contact surface between the socket and the fastener, increasing the locking force, reduces wear and prevents rounding off at corners.
