Klein Tools 32787 64-Piece Precision Ratchet and Micro Screwdriver System

The Klein Tools 32787 Precision Ratchet and Driver System combines a low-profile micro-ratchet, a magnetic adjustable Cushion-Grip screwdriver handle, and 60 precision and standard driving bits within a MODbox-compatible modular storage case. Forged from high-grade heat-treated tool steel, this 22.56 oz (1.41 lb) multi-drive fastener kit includes 33 precision bits, 16 standard 1/4-inch hex bits, and 11 nut drivers engineered for sensitive electronic assemblies, HVAC control boards, and fine terminal connections. Featuring magnetic bit retention across both 1/4-inch and 3.5 mm drive sockets alongside a free-spinning handle cap, this system allows electrical contractors and field service technicians to apply controlled rotational torque in restricted clearance spaces.

Best Used For:

  • Control Panel & PCB Board Maintenance: Fastening micro-terminal screws, circuit board standoffs, and delicate electronic component housings without stripping threads.
  • Confined Space Fastening: Reaching restricted equipment recesses and low-clearance cabinet corners using the low-profile micro-ratchet or adjustable length driver shanks.
  • Modular Jobsite Storage Integration: Stacking and latching the MODbox system case directly onto compatible Klein driver cases for streamlined field organization.

Key Performance & Safety Features

  • 64-Piece Comprehensive Fastening Kit: Contains 33 precision micro-bits, 16 standard bits, 11 nut drivers, 1 bit adapter, 1 adjustable handle, 1 micro-ratchet, and 1 MODbox case.
  • Low-Profile Forward/Reverse Micro-Ratchet: Delivers high lever torque in tight enclosures and features an integrated tether point for fall protection safety.
  • Dual Magnetic Adjustable Bit Holders: Accepts both 3.5 mm precision micro-bits and standard 1/4-inch hex bits with strong magnetic fastener retention.
  • Cushion-Grip Handle with Spin Cap: Ergonomic CA/TPE handle design optimizes user grip comfort while the rotating end cap allows precise fingertip control during micro-fastening.
  • MODbox System Modular Connectivity: Interlocking case frame connects seamlessly to other Klein modular driver cases for secure transport.

Pro-Tip: When servicing delicate circuit board terminal screws, place your palm against the free-spinning end cap of the driver handle and turn the body with your fingers. This maintains steady axial alignment pressure without over-torquing or slipping off fragile screw heads.
