Product Description
Our scaffolding wrench is forged from premium special tool steel for high strength, excellent toughness, and long-lasting durability. Designed specifically for construction workers, it’s mainly used for disassembly and installation of 19mm, 21mm, and 22mm nuts and bolts — the dedicated tool for scaffolding erection and dismantling. Open-end design allows quick engagement with nuts, improving work efficiency. Full-body heat treatment ensures uniform hardness, impact resistance, and wear resistance. Available in 250mm and 300mm sizes to meet different work requirements.
Key Features
- Forged Special Tool Steel — Precision drop-forged from high-grade special tool steel for high density, superior strength, excellent toughness, impact resistance, and wear resistance — built for heavy-duty construction site use.
- Construction-Specific, 19/21/22mm Compatible — Designed specifically for construction workers, suitable for 19mm, 21mm, and 22mm nuts and bolts — the standard tool for scaffolding work.
- Open-End Quick Operation — Open-end design allows engagement with nuts from the side, no need to thread on from the bolt end — dramatically improves scaffolding erection and dismantling efficiency.
- Full-Body Heat Treatment — Entire wrench undergoes heat treatment for uniform hardness throughout, excellent impact resistance, and resistance to deformation under heavy use.
- Ergonomic Handle — Ergonomically shaped handle for comfortable grip and smooth force application — reduces hand fatigue during prolonged work.
- Box End at Tail — Integrated box wrench head at the handle tail — one wrench, two uses, added practicality.
- Two Sizes Available — 250mm and 300mm lengths to meet different work scenarios and force requirements.

FAQ
Q1: What is the MOQ?
A : The MOQ for standard models is 1 carton (40 pcs), with mixed sizes supported. For custom logo engraving, the MOQ is 500 pcs — please contact our sales team for details.
Q2: Can you provide samples?
A : Yes. We provide free samples (freight collect), usually shipped within 3-5 business days. Note: This product is being discontinued, while supplies last — we recommend ordering soon.
Q3: Why does a 21mm opening work for 19/21/22mm nuts?
A : Scaffolding coupler nuts are typically 21mm (across flats), and 19mm and 22mm are also common nut sizes on construction sites. A 21mm opening wrench can securely grip 19mm nuts for normal use, and 22mm nuts fit tightly but work — so one wrench covers multiple common nut sizes on job sites.
Q4: What’s the difference between a scaffolding wrench and a standard open-end wrench?
A : Key differences: ① Better material — special tool steel forging is more impact-resistant; ② Jaw size specifically designed for scaffolding coupler nuts; ③ Full-body heat treatment withstands hammer strikes; ④ Longer handle for greater leverage; ⑤ Box end at tail adds second function. Designed specifically for construction site conditions.
Q5: What is the lead time?
A : In-stock items ship within 7 days. Custom orders typically take 25-35 days, depending on order quantity and customization requirements. Note: This product is being discontinued, stock is limited.
Q6: Do you offer a warranty?
A : We offer a 1-year quality warranty. Any non-human-caused quality issues are eligible for free return or replacement — 100% quality guarantee.
