Combination spanner OPEN BOX 13 size 50 mm, length 530 mm, AS-Drive bi-hex ring - Stahlwille 40085050

Large hex fasteners with size 50 mm need a spanner that transmits torque reliably and offers enough leverage. The OPEN BOX 13 combination spanner provides 530 mm of length, a bi-hex ring with AS-Drive profile on one end and an open jaw angled 15° on the other. The AS-Drive profile engages on the flanks instead of the corners, protecting heavily stressed bolt heads.

Benefits

• Bi-hex ring with AS-Drive profile (Anti-Slip-Drive)
• Ring end cranked 15° for easy work on flat surfaces
• Jaw angled 15°, reinforced connection between jaw and shaft
• High flexural strength due to double-T profile, slim thin-walled rings for tight spots
• STAHLWILLE rounded finish for a non-slip grip, safe even with oily hands
• Drop-forged, hardened and cooled in an oil bath, Chrome Alloy Steel, chrome-plated

Applications

Assembly and maintenance on large hex fasteners in workshops, plant engineering and DIY, wherever a size of 50 mm is tightened or loosened by hand.
