Description
The Sidchrome 440 Pro Series Ring & Open End Spanners are engineered for high performance in demanding environments. They feature a modern structural design that balances compactness with extreme strength. A key safety feature of the 440 Pro Series is its controlled distortion mechanism; instead of snapping suddenly when critical torque is reached, the tool distorts gradually, significantly reducing the risk of injury to the user.
Features:
- I-Beam Shank: A revolutionary design that provides superior strength and enables the delivery of higher torque with less effort.
- Ring End Step Down: Features a sharp step down on the ring end to facilitate access to fasteners in highly restricted or recessed spaces.
- Patented AntiSlip Fastening System: The open end includes a locking groove design that prevents the spanner from slipping off the fastener, protecting the user’s knuckles.
- TorquePlus Fastening System: The ring end drives from the flats of the fastener rather than the corners, spreading the load over a larger surface area for better torque and reduced rounding of fasteners.
- Safety Design: Engineered to bend gradually under extreme load rather than shattering, providing an added layer of workplace safety.
