Klein Tools 33800 35-Piece S2 Steel Impact Driver Bit Set

The Klein Tools 33800 35-Piece Impact Driver Bit Set operates as an industrial-grade mechanical driving system engineered to install and remove heavy-duty fasteners across commercial electrical panels, HVAC ductwork, and structural timber assemblies. Weighing 1.08 lbs. and organized inside a MODbox-compatible storage case measuring 7.0 in. L x 3.75 in. W x 1.75 in. H, this kit includes heat-treated S2 tool steel driver bits, extended 2-inch power bits, 1/4-inch and 5/16-inch magnetic power nut drivers, a 3/8-inch square impact socket adapter, and a 3-inch magnetic bit extension holder. Manufactured with precision-milled bit geometry and minimal-chamfer hex socket walls, this multi-drive kit enables electricians, HVAC technicians, and carpenters to transfer high-torque rotational forces directly to screw heads and hex fasteners using 1/4 in. power impact drivers without rounding edges or fracturing bit tips.

Best Used For:

  • High-Torque Power Screwdriving: Fastening self-tapping sheet metal screws, wood lag bolts, and electrical grounding hardware using 1/4 in. power impact drivers.
  • Recessed Fastener Installation: Utilizing extended 2-inch #2 Phillips and #2 square bits alongside the 3-inch magnetic extension to reach deep electrical junction boxes and cabinet framing.
  • Hex Hardware & Socket Driving: Driving 1/4-inch and 5/16-inch hex nuts or adapting to 3/8-inch square drive impact sockets for structural bolt fastening.

Key Performance & Safety Features

  • S2 Impact-Rated Tool Steel: Heat-treated S2 alloy steel construction absorbs rotational shock loads from cordless impact drivers to prevent premature snapping.
  • Precision-Milled Driver Tips: Machined tip profiles deliver exact fastener fitment, reducing cam-out and stripping on high-torque screws.
  • Extended 2-Inch Power Bits: Features extended #2 Phillips and #2 Robertson square bits for direct reach into confined structural cavities.
  • Minimal Chamfer Magnetic Nut Drivers: 1/4 in. and 5/16 in. power nut drivers feature flat internal hex walls to maximize surface contact on thin sheet metal nuts.
  • 3-Inch Magnetic Extension Shaft: High-strength permanent magnet within the 3 in. bit holder retains 1/4 in. hex bits and screw hardware during overhead driving.
  • MODbox Compatible Modular Storage Case: Hard-shell impact-resistant storage box with steel hinge pins, spring-loaded latch, and stackable interlocking feet.

Pro-Tip: When driving shallow sheet metal hex screws or HVAC ductwork fasteners, utilize the included 1/4 in. or 5/16 in. magnetic nut drivers. Their minimal-chamfer interior design maximizes wall contact with thin screw heads, preventing the driver from slipping under power and stripping shallow hex edges.
