Nine stainless steel ball-end hex keys in a holder

Wera Tools 022720 Stainless Steel Ball End Hex Key Set 9 Piece

SKU CH-0WKH-ZRP61

Nine-piece metric stainless hex key set with Hex-Plus short arms and ball-end long arms for corrosion-resistant fastening

  • Stainless steel resists corrosion in marine environments
  • Vacuum ice-hardening delivers industrial-grade hardness and strength
  • Hex-Plus profile protects screw heads from rounding out
  • Ball-end long arms allow angled access to fasteners
  • Nine metric keys cover 1.5 to 10.0 mm sizes

Marine Stainless Hex Key Set

The Wera 022720 set supplies nine metric hex keys manufactured from vacuum ice-hardened stainless steel for corrosion-resistant fastening on boats and dockside equipment. Sizes range from 1.5 to 10.0 millimetres with lengths matched to each dimension. The Hex-Plus profile on the short arm protects screw heads from rounding while the ball-end on the long arm allows angled access in tight bilge or rigging spaces.

For Corrosion-Critical Assembly

Mechanics who need non-magnetic, rust-free tools for stainless steel hardware on marine vessels will appreciate the material choice and Hex-Plus geometry. Technicians working exclusively on carbon steel fasteners in dry workshops or who require colour-coded handles for quick size identification should look elsewhere.

Holder Keeps Keys Organised

The included clip holder secures all nine keys in size order so the correct wrench is immediately visible during a refit or emergency repair. No additional software, lubricants or adaptors are supplied, so the kit arrives ready for immediate use without extra preparation.

Questions about this item

What metric hex fasteners will the 1.5 mm to 10.0 mm keys in this set fit?

The set covers metric sizes 1.5, 2.0, 2.5, 3.0, 4.0, 5.0, 6.0, 8.0 and 10.0 mm, matching the corresponding socket-head or set-screw threads.

Can I use these stainless keys on standard carbon-steel hex screws without damaging the heads?

Yes, the Hex-Plus profile on the short arm spreads torque over wider contact surfaces, reducing the risk of rounding carbon-steel heads.

How do I confirm the vacuum ice-hardened stainless keys are hard enough for industrial torque loads?

Apply rated torque to a known-good fastener; the key should not permanently deform and the screw head should show no rounding.
