Wiha 36689 ERGOSTAR Torx Ball End L-Key Set 13-Piece
Reach awkward recessed Torx fasteners without stripping screw heads using the Wiha 36689 13-Piece ErgoStar® Torx® Ball End L-Key Set. Engineered in Germany for precision mechanics, aerospace engineers, automotive technicians, and industrial maintenance crews, this comprehensive collection covers everything from tiny electronic assemblies up to heavy machinery bolts (T5 through T45).
Forget the frustration of fumbling with tangled hex holders. Wiha’s patented ErgoStar® mechanical holder turns the entire set when you rotate any single key, instantly fanning out all sizes for effortless, one-handed selection. The long arm features an engineered ball end tip (on T9 through T45) that allows a 25° working angle, letting you drive fasteners in blind, off-axis, or confined spaces where straight-on access isn't possible. Machined from premium through-hardened CRM-72 tool steel with a corrosion-resistant black oxide finish, these German L-keys deliver an exact fastener fit that prevents rounded star lobes and cam-out damage.
Key Features:
- Patented ErgoStar® Quick-Access Holder: Turn any single L-key and all keys rotate forward in unison, making retrieval and return effortless.
- 25° Off-Axis Ball End (T9–T45): Drives Torx screws at up to a 25-degree angle in recessed or obstructed locations.
- Full 13-Piece Comprehensive Range: Spans micro-precision electronics sizes up to structural fasteners: T5, T6, T7, T8, T9, T10, T15, T20, T25, T27, T30, T40, and T45.
- German CRM-72 Tool Steel: Through-hardened chrome-vanadium-molybdenum alloy steel provides high tensile strength and prevents twisting under heavy torque.
- Precision CNC-Machined Tips: Exact-fit tolerances seat deep into Torx lobes to eliminate play, slippage, and stripped screw heads.
- Corrosion-Resistant Black Oxide Coating: Durable finish protects against shop oils, atmospheric moisture, and corrosion.
- Extra-Long Arm Leverage: Extended blade length delivers the reach needed for deep recesses and maximum loosening leverage on stubborn fasteners.

Frequently Asked Questions
Do all 13 keys in the set have ball ends?
Sizes T9 through T45 feature the 25° ball end on the long arm. The smaller micro sizes (T5, T6, T7, and T8) have standard straight Torx ends on both the short and long arms, as ball ends at these sub-miniature diameters would lack the torsional strength required to prevent shearing.
How does the patented ErgoStar® holder work?
The ErgoStar holder uses an internal geared mechanical linkage. When you turn any single L-key to the side, all other keys rotate forward simultaneously in a stepped fan pattern. This allows you to remove or replace any size without bumping adjacent keys.
Can the ball end be used to break loose extremely tight screws?
While Wiha ball ends are through-hardened and exceptionally strong, best practice is to use the short straight arm for breaking loose frozen or over-torqued fasteners, then switch to the long ball end for rapid spin-out at an angle.
Will these keys fit standard Torx and star screws?
Yes. They fit all standard 6-lobe Torx, Star, and ISO 10664 fasteners commonly found in automotive assemblies, European machinery, electronic enclosures, and premium power tools.
Where are these Wiha L-keys manufactured?
The Wiha 36689 ErgoStar set is manufactured in Germany from high-grade CRM-72 tool steel, adhering to strict DIN and ISO industrial tolerances.
