Powerbuilt

Powerbuilt 9 Piece SAE Stubby Long Arm Ball End Hex Key Wrench Set Blue 240099

SKU CH-0QT3-32Q6A

Nine SAE hex keys with 25-per-cent shorter stubby ends, extra-long arms and ball ends that work at up to 25-degree angles, made from chrome vanadium steel and supplied in a folding carrier

  • TypeHex Key Accessories
  • Stubby ends 25% shorter reach tightest spots
  • Extra long arms add reach and leverage
  • Chamfered faces reduce rounding and cam-out
  • Ball ends turn fasteners at 25 degree angles
  • Chrome vanadium steel built to last lifetime

Tight-Space Hex Set for Mechanics

The Powerbuilt 240099 set contains nine SAE stubby long-arm hex keys sized from 1/16" to 3/8". Stubby ends are 25% shorter than regular keys so they fit into the tightest spots where standard L-wrenches cannot reach. Ball ends on the long arms work at angles up to 25 degrees for off-axis fastener access. Chrome vanadium steel construction meets or exceeds ANSI standards for professional durability.

Nine-Size Range Covers Common SAE Fasteners

The kit spans 1/16", 5/64", 3/32", 1/8", 5/32", 3/16", 1/4", 5/16" and 3/8" to handle the most frequent hex-head sizes in automotive and equipment repair. Extra long arms add reach and leverage for tightening or loosening stuck bolts. Chamfered hex faces give a precise fit that reduces rounding or cam-out. The set runs out when a metric fastener or a size outside the 1/16" to 3/8" range appears.

Compact Carrier Keeps Keys Organised in a Toolbox

A folding plastic carrier holds all nine wrenches securely and slips into a toolbox or glovebox without rattling. Low-profile L-wrench design frees up clearance in cramped engine bays or machinery frames. Builders who need metric sizes, torque-limiting handles, or a ratcheting mechanism will need a different kit. The carrier and stubby geometry together keep the essential SAE range ready for immediate use.

Questions about this item

Will the 1/16 in stubby ends fit the same tight spots as my older full-length hex keys?

The stubby ends are 25% shorter than regular hex keys, so they reach fasteners in tighter spaces where longer keys cannot turn.

How can I confirm the ball ends on the long arms are engaging correctly at an angle?

The ball ends work at angles up to 25 degrees; you will feel positive engagement without rounding the fastener when the chamfered faces seat fully.

Does the set include a holder for the nine wrenches or must I buy a separate organiser?

A folding plastic carrier is included to keep all nine SAE sizes organised and ready for a toolbox.
