Last reviewed June 14, 2026
TL;DR A 22-piece metric + SAE ball-end hex L-key set in Bondhus Protanium chrome-vanadium steel · 9 metric sizes (1.5·10 mm) and 13 SAE sizes (0.050·3/8 in), with ball-end on every long arm confirming fastener engagement at up to 25° off-axis. No deformation complaints reported by a large, devoted owner base; lifetime GorillaProof warranty backed by community-confirmed no-questions-asked replacement. No Torx keys · buyers needing T25, T27, T40, or T45 for brake or suspension work need a separate Torx set.
A 22-piece L-key hex set in two color-coded Bondhex clip holders · metric (1.5, 2, 2.5, 3, 4, 5, 6, 8, 10 mm) and SAE (0.050, 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, 1/4, 5/16, 3/8 in). All 22 keys use Bondhus Protanium alloy steel · the brand's proprietary chrome-vanadium designation · and carry ball-end tips on the long arm for 25° off-axis engagement. The standard L-key format provides high-torque leverage on the long arm and confined-access reach on the short arm. Owners broadly report no steel deformation on brake caliper slides, drain plugs, and interior panel fasteners; no fastener-rounding complaints appear in the review sample. Lifetime GorillaProof warranty covers bent or broken keys with documented hassle-free replacement across the user base.
Right pick for a home mechanic who wants comprehensive metric and SAE hex coverage for domestic and import vehicle work · every critical automotive hex size from 1.5 mm through 3/8 in is present, and the Protanium steel handles normal DIY torque loads without documented deformation. Skip if your vehicle uses Torx hardware for brake or suspension service (T25 brake pad retaining pins, T27 Ford/GM caliper bolts, T40/T45 European caliper bracket bolts) · this is a hex-only set and a separate Torx set is required for Torx-fastened brake systems.
Alloy steel hand tools with no chemical exposure pathway · health score reflects physical-use safety only. Protanium chrome-vanadium steel with community-confirmed decade-plus lifespan minimizes replacement cycles; alloy steel is recyclable through standard ferrous scrap collection. Penetrating oils or thread-locking compounds used with these keys carry their own hazard profiles · check the individual product review for guidance specific to each chemical.
No · the 20199 is a hex-only set. It covers 9 metric hex sizes (1.5·10 mm) and 13 SAE hex sizes (0.050·3/8 in). Buyers who need T25, T27, T40, or T45 Torx keys for brake or suspension work require a separate Torx set.
Bondhus uses Protanium steel · the brand's proprietary designation for their chrome-vanadium alloy. the product specifications list the material as 'Alloy Steel.' Owners broadly report no deformation on brake caliper slides, drain plugs, and similar automotive hex-socket fasteners under normal DIY torque loads.
Yes · all hex keys in both the metric and SAE sets have ball-end tips on the long arm. Bondhus notes these work at up to 25° off-axis, allowing continuous turning without repositioning the tool when a fastener is partially obstructed.
Amazon lists a Prop 65 warning for this product. For alloy steel tools, Prop 65 warnings typically trace to chromium and nickel compounds present in the steel alloy itself. The warning is required under California law when listed substances are present above threshold concentrations; it does not reflect a health hazard from normal hand-tool use.
The 20199 DoublePK ships as a clamshell package containing two color-coded Bondhex clip holders: a yellow metric holder (9 keys, 1.5·10 mm) and a red SAE holder (13 keys, 0.050·3/8 in). Both holders are reusable · wrenches slip into individually marked slots and twist to lock.
