Hand tool for tightening and loosening flat-sided fasteners, designed to reach cramped spaces and resist wear, the sourcing map Open End Wrench suits workshop and DIY tasks. Confidence during repairs comes from a thin profile, a 15-degree offset and clear engraved sizing that reduce guessing. Will the focused size and shape earn a place in your toolkit?
⚡ At a Glance
- • Wrench Accessibility: Thin open head and 15-degree offset for access in confined spaces
- • Best for: Automotive repair, plumbing, furniture assembly and general DIY tasks
- • Not ideal for: Fastening tasks that require variable sizes or socket reach
Open end measures 52mm across flats and total length is 240mm. Carbon steel construction with a blackened finish improves wear resistance and helps prevent corrosion.
Reach tight spaces - with 15-degree opening angle
A 15-degree offset lifts the head away from the shank, giving extra clearance when approaching bolts at awkward angles. Thin head profile and U-shaped open end reduce interference in narrow gaps.
Easier engagement with fasteners in engine bays, behind fittings, and between furniture frames, where a straight open spanner would struggle.
Longer service life - thanks to carbon steel and blackened finish
High-hardness carbon steel provides strong wear resistance under repeated torque, while the blackened surface reduces surface oxidation and helps shield steel from corrosion.
Suitability for regular garage use and DIY projects, with lower likelihood of premature surface wear or rust.
Faster tool selection and steadier grip - with engraved markings and a red shank
Clear size markings are engraved onto the head for instant identification, and the shank width and thickness give a firm contact area for the hand when applying torque.
Quicker swaps between fasteners and a more confident grip during tightening or loosening, reducing slips and downtime.
