This Reversible Geared Spanner Set from SIDCHROME provides the ultimate versatility in any application. The open end of the Sidchrome spanner features the ANTISLIP design - a locking groove prevents slippage and knuckle injury. 
The Ringstop Gothru System which employs a patented rung within the geared ring end of the ratchet which prevents the spanner from slipping past the fastener. Extremely useful when working on long bolts, or in positions where it is inconvenient to use the other hand to keep the tool on the fastener.

Features & Specifications

• 40% more compact than the standard ratchet combination spanner
• Ring head: ratchet mechanism with 5° increments, with 15° angle
• Open end oriented at 15°
• "AntiSlip Design" - or ASD. ASD features a locking groove and unique geometry, to deliver 400% more surface area than a conventional spanner. 
• This delivers greater torque to the fastener, significantly reduces the chance of dangerous slipping and allows the job to be completed faster.
• The ring end on Sidchrome spanners features Sidchrome's unique TorquePlus fastening system.
• This unique system allows greater contact with the flats of the fasteners, providing greater torque to enable easier fastening. 
• As conventional sockets damage fasteners by concentrating forces on the corners, Sidchrome TORQUEPLUS spanners spread the force over a larger contact area, reducing rounding off and extending fastener life.
• As a result, Sidchrome TORQUEPLUS spanners are particularly useful on worn or rounded fasteners. 
• You can be sure Sidchrome spanners are tough enough to stand up to the harshest working environment.
