⚡ At a Glance
- • Fit Range: Fits 78–85mm round nuts, 270mm total length for good reach
- • Best for: Workshop and motorcycle maintenance tasks that need precise nut adjustment
- • Not ideal for: Fine plumbing work or nuts outside the 78–85mm range
Forged carbon steel construction is heat-treated for hardness and black oxidised to resist corrosion. Red rubber-covered handle is ergonomic and includes a designation number for quick identification.
Controlled Torque for Heavy Duty Use – thanks to forged carbon steel
Forged carbon steel provides high toughness and wear resistance, with a solid, single-piece construction that withstands repeated loading. High-frequency hardening increases strength at the contact surfaces for better resistance to deformation.
Secure nut adjustment with minimal bending, ideal for shock absorber preload and other high-torque workshop tasks.
Longer Lifespan in Workshop Environments – with black oxidised surface treatment
Black oxidised treatment and high-frequency hardening create a hard, corrosion-resistant surface that slows wear and pitting. The finish reduces the risk of surface rust in damp or oily conditions.
Tool remains reliable over time even with regular exposure to workshop oils and moisture, reducing the need for frequent replacement.
Comfortable, Slip-Resistant Handling – thanks to red rubber-covered handle
Red rubber covering provides a textured grip and ergonomic shape for optimal force transmission, while a printed designation number on the handle helps with quick size selection.
Firm, comfortable grip makes repetitive adjustments less fatiguing and speeds up identification on a busy bench.
