This product is a striking wrench with a hole for a string at the rear end of the handle, which loosens stuck nuts with a single blow while pulling.
By passing a rope through the hole at the handle end and pulling in the tightening direction while hitting the striking part with a hammer, you can loosen or tighten stuck bolts and nuts with one hand.
It is suitable for removing the nut of a vertical washing machine's drum that does not move with hand turning, and for removing water fittings that have been stuck outdoors for many years.
The striking part has a robust shape with sufficient thickness, designed for hammering, and effectively transmits force even during repeated impacts with large vibrations.
Because the position where you grip with your hand and the impact position are separated, you can manage the force application direction and the striking direction separately, allowing stable work even in narrow spaces.

The main body is made of steel formed by hot forging, which has a dense metal structure and excellent durability and load-bearing properties.
The surface is coated with cation paint (electrophoretic black coating), which makes it resistant to rust even when used in humid environments such as outdoor water fittings, garden sprinklers, and nuts under balcony waterproof pans.
The coating film is uniform and resistant to peeling during impact, and the matte texture is maintained even after long-term storage when the wrench is taken out.
It can be used on outdoor DIY sites such as maintenance of equipment exposed to rain, piping in old buildings, and agricultural machinery, reducing slipping and poor engagement caused by rust on the tool itself, and transmitting stable impact torque.
Although impact marks may appear, the coating protects the underlying steel material.

The 12-point wrench part and size printing in the center of the main body prevent misselection; the wrench has a 12-sided shape, allowing the bolt or nut head to be engaged from six directions.
Even in narrow workspaces, it can be turned at 30-degree increments, enabling engagement with nuts in limited spaces.
The center of the main body has engraved size markings (38 or 36), so even when multiple tools are stored side by side in a toolbox, the size can be identified immediately upon lifting at the work site.
It prevents accidents such as stripping the nut threads by mistakenly fitting the wrong size wrench, and can be used with confidence in situations like disassembling washing machines where a single operation is desired.
The feature that allows size confirmation on the surface before impact provides practical benefits for both professional use and DIY maintenance.

This product is available in two sizes, 38mm and 36mm, optimized for removing and tightening the fixing nuts of vertical washing machine drums, with dimensions and thickness suitable for such tasks.
It is effective in situations where manual turning is impossible, such as nuts under impellers that cannot be removed by hand, rusted fittings that no longer turn, and stuck nuts at pipe joints.
The handle length is 20.5cm, making it compact and easy to swing even in narrow spaces like inside washing machines, and designed to facilitate control of the impact direction.
The heavy striking part allows even those with less strength to transmit torque with a single hammer blow.
Having one in your toolbox is useful for DIY enthusiasts and repair professionals who want to perform maintenance on equipment themselves, especially for sudden stuck cases.

Product specifications: Material: Steel (hot forged), Cation coating / Size: Total length 20.5cm x width 6.5cm (compatible with 36mm) / Wrench part: 12-sided / Features: Handle end with hole for string, size printed in the center / Uses: Removing and tightening stuck nuts of washing machine drums, water fittings, and pipe joints.
Precautions: Not suitable for bolts and nuts other than the supported sizes (38mm or 36mm) / Avoid using on thin nuts such as plumbing nuts that are significantly thinner than the wrench thickness, as it may cause slipping or stripping / During impact, ensure the wrench is firmly engaged with the nut and strike straight, paying attention to avoid falling or pinching fingers due to the weight of the main body.
