Hex Key Set KWB 147790 — 8-piece metric set, durable steel

KWB 147790 is an 8-piece metric hex key (Allen) set made from durable steel. The set includes eight common metric sizes that cover most household and workshop hex fasteners. Its compact holder keeps the tools organized and easy to transport, while the hardened steel construction provides reliable torque and wear resistance for repetitive tightening and loosening tasks.

Advantages

The hex keys are manufactured from durable, hardened steel to resist bending and wear under normal mechanical loads. The compact, numbered holder arranges the keys for quick selection and safe storage. Hex key ends are machined for accurate fit into hex sockets, reducing the risk of stripping fasteners. The set offers consistent torque transmission and predictable performance across a range of common sizes.

How to use

Select the hex key size that fits snugly into the fastener recess, insert the short or long arm depending on required reach and leverage, and apply steady torque. Use the long arm for greater leverage on tight fasteners and the short arm for better access in confined spaces. Store the keys in the compact holder after use to protect the tools and keep sizes organised.

Recommendations

Inspect hex keys for wear and rounded edges before use; replace damaged keys to avoid fastener damage. Apply lubricant to stubborn fasteners if needed and use controlled force to prevent slipping. For high-torque applications, use appropriately sized tools or a dedicated torque wrench where required.
