Hex Key Set YATO YT-0501 — 9-piece hex key (Allen) set, metric sizes

YATO YT-0501 is a 9-piece metric hex key (Allen) set designed for tightening and loosening hex-socket fasteners. The set includes nine commonly used metric sizes in a compact holder, offering a practical tool selection for workshop, garage or service environments. Made for routine assembly, maintenance and repair tasks, this hex key set is suitable for use on furniture, bicycles, appliances and light machinery where access to recessed hex heads is required.

Advantages

The set provides a compact, organized selection of metric hex keys that simplifies storage and handling. Each key delivers a precise fit to minimize rounding of fasteners and enable consistent torque transfer. The holder keeps tools together for quick selection and transport, while the straight L-shaped profile allows both standard and extended reach when working in tight spaces.

• Assembly and disassembly of furniture with hex-socket fasteners
• Bicycle maintenance and component adjustments
• Repair and servicing of household appliances
• Light machinery maintenance and workshop tasks

Key specifications

• Set size: 9 pieces
• System: metric hex (Allen)
• Form factor: L-shaped hex keys
• Material: hardened steel (tool-grade finish)
• Storage: compact holder for organization and transport

How to use

Select the hex key that matches the hex-socket size of the fastener to ensure a snug fit. Insert the short end into the fastener for higher torque or use the long end as a handle for improved reach and leverage. Turn clockwise to tighten and counterclockwise to loosen, applying steady pressure to avoid cam-out. Use the holder to keep the keys organized and to carry the set to the worksite.

Usage recommendations

Inspect fastener heads before use to ensure compatibility and avoid tool slippage. For high-torque applications, use the longer arm for increased leverage and consider applying a torque-limiting device if required. Store the set dry and clean after use to prevent corrosion and maintain fit accuracy.
