Combination spanner OPEN BOX 13a imperial size 1 7/8 inch length 530 mm - Stahlwille 40487070

Large fasteners with an imperial size of 1 7/8 inch, for example on machinery and plant built to imperial standards, call for considerable force. With a length of 530 mm, the OPEN BOX 13a combination spanner provides a long lever arm and transfers the torque safely to the nut or bolt via ring or jaw.

Benefits

• Ring with bi-hex and AS-Drive profile: force is applied to the flanks, protecting the edges of the nut or bolt
• Ring end cranked 15°, jaw angled 15° for good access
• Thin-walled rings for fastening points with little space
• High flexural strength due to the double-T profile and reinforced connection between jaw and shaft
• Drop-forged, hardened and cooled in an oil bath, Chrome Alloy Steel, chrome-plated
• STAHLWILLE's rounded finish ensures a non-slip, pleasant feel

Applications
