Klein Tools 65213HEXM 13-Piece Metric Knurled Hex Bit Socket Set

The Klein Tools 65213HEXM 13-Piece Knurled Hex Bit Socket Set operates as an internal driving array engineered to turn metric socket head cap screws and hex set screws across industrial machinery and electrical equipment. Housed in a MODbox-compatible storage case measuring 7 in. L x 3-45/100 in. W x 1-63/100 in. H and weighing 1.41 lbs., this kit contains 13 metric hex bit sockets spanning 2 mm to 14 mm distributed across 1/4 in., 3/8 in., and 1/2 in. drive platforms. Manufactured from forged chrome-vanadium steel bodies with black phosphate steel bit tips, this set features raised perimeter knurling on each socket base to allow trade technicians to hand-start fasteners before applying full torque with ratchets or torque wrenches.

Best Used For:

  • Metric Internal Hex Fastener Assembly: Installing and removing socket head screws and set bolts from 2 mm through 14 mm in commercial equipment enclosures.
  • Tactile Manual Fastener Pre-Threading: Utilizing precision base ring knurling to spin threaded fasteners down by hand in tight or oil-slicked workspaces.
  • Scaled Torque Drive Applications: Utilizing 1/4 in. drive for low-torque precision (2 to 6 mm), 3/8 in. drive for general driving (7 to 10 mm), and 1/2 in. drive for high-torque applications (12 to 14 mm).

Key Performance & Safety Features

  • Knurled Socket Base Collar: Raised perimeter knurling provides non-slip finger contact for hand-starting delicate metric fasteners.
  • Optimized Progressive Drive Scaling: Scaled across 1/4 in., 3/8 in., and 1/2 in. square drives to match appropriate rotational torque limits for each bit diameter.
  • Forged Chrome-Vanadium Metallurgy: Polished chrome-vanadium alloy steel bodies combined with heat-treated black phosphate bit tips resist wear and corrosion.
  • Bold Stamped Size Identification: Permanent stamped size callouts on each socket wall enable quick size identification in low-light environments.
  • MODbox Modular Organizer Case: Hard-shell transparent lid case features a one-handed spring latch and an internal small parts tray for loose hardware.

What's Included

  • (7) 1/4 in. Drive Metric Hex Bit Sockets (2 mm, 2.5 mm, 3 mm, 4 mm, 4.5 mm, 5 mm, 6 mm)
  • (4) 3/8 in. Drive Metric Hex Bit Sockets (7 mm, 8 mm, 9 mm, 10 mm)
  • (2) 1/2 in. Drive Metric Hex Bit Sockets (12 mm, 14 mm)
  • (1) MODbox™ Compatible Clear-Lid Storage Case with Parts Tray

Pro-Tip: When installing small 2 mm to 4 mm metric set screws in machinery collars, grip the socket base's knurled ring directly between your fingers. Pre-threading the fastener by hand prevents cross-threading delicate internal aluminum or brass threads before attaching your 1/4 in. drive ratchet to apply final torque.
