Klein Tools 65213TX 13-Piece Knurled TORX Star Bit Socket Set
The Klein Tools 65213TX 13-Piece Knurled TORX Bit Socket Set operates as a star-drive mechanical fastening system engineered to engage and turn internal Torx-head fasteners across automotive, machinery, and electrical equipment assemblies. Weighing 1.43 lbs. and organized inside a MODbox-compatible storage case measuring 7 in. L x 3-45/100 in. W x 1-63/100 in. H, this kit contains 13 star-bit sockets spanning sizes T8 through T60 distributed across 1/4 in., 3/8 in., and 1/2 in. drive platforms. Manufactured from forged chrome-vanadium steel bodies with S2 alloy steel bit inserts finished in black phosphate, each socket features a textured base ring to allow trade technicians to hand-start fine-thread screws before applying full torque with ratchets or torque wrenches.
Best Used For:
- Internal TORX Fastener Maintenance: Installing and removing star-drive machinery screws and housing bolts from T8 up to T60 in commercial HVAC and electrical equipment.
- Fingertip Fastener Threading: Utilizing precision base ring knurling to manually pre-thread star-head screws in tight or oil-slicked workspaces without tool slippage.
- Scaled Torque Drive Applications: Matching small precision screws to 1/4 in. drive (T8-T25), mid-range hardware to 3/8 in. drive (T27-T45), and heavy structural bolts to 1/2 in. drive sockets (T47-T60).
Key Performance & Safety Features
- Knurled Socket Base Collar: Textured perimeter knurling provides non-slip finger contact for rapid hand-starting of delicate star-drive fasteners.
- Optimized Progressive Drive Scaling: Scaled across 1/4 in., 3/8 in., and 1/2 in. square drive interfaces to match appropriate rotational torque limits for each bit size.
- S2 Alloy Steel Bit Construction: High-strength S2 alloy steel inserts with black phosphate coating offer high torque resistance to prevent tip cam-out and corrosion.
- Chrome-Vanadium Socket Bodies: Polished chrome-plated alloy steel sockets resist rust, chipping, and mechanical stress under heavy ratchet leverage.
- High-Visibility Stamped Size Markings: Permanent size callouts stamped into socket walls allow quick identification in low-light industrial settings.
- MODbox Modular Organizer Case: Clear-lid storage case features a one-handed spring-loaded latch and an embedded small parts tray for loose screws.

Pro-Tip: When servicing recessed TORX screws in engine bays or machinery housings, use the knurled socket collar to hand-thread the bit firmly into the fastener head before attaching your ratchet. This ensures full 6-point star engagement and prevents stripping shallow star recess teeth under torque application.
