Wrench BAHCO 11M-19 — 19 mm steel open-end wrench, metallic finish, 310 mm length

BAHCO 11M-19 is a 19 mm open-end wrench manufactured from high-performance alloy steel with a metallic chrome-micro-matte finish. The tool is 310 mm long and weighs approximately 290 g, designed for manual tightening and loosening of 19 mm fasteners in mechanical, automotive and maintenance tasks. The wrench combines a slim angled open end and a 12-point ring profile to offer accessibility and reduced fastener wear while meeting relevant international standards.

Advantages

The 11M-19 features a 15° angled open end with a slimmer head to improve access in confined spaces. A 15° angled ring end provides knuckle clearance and improved positioning. The 12-point Dynamic-Drive™ profile on the ring end spreads load over a larger surface area, reducing wear on screws and nuts. Chrome plated micro-matte finishing gives a durable, high-quality surface and the patented U-shaped shank design enhances comfort during use. Clear imprinting eases tool identification.

Suitable for

• Manual tightening and loosening of 19 mm bolts and nuts
• Automotive repair and maintenance where 19 mm fasteners are common
• General mechanical and workshop tasks requiring an accessible open-end wrench
• Maintenance work in confined or hard-to-reach areas

How to use

Select the 19 mm jaw over the fastener so the open end or the ring end fully engages the nut or bolt. Apply steady, even force while keeping the wrench aligned with the fastener axis to avoid slipping. Use the slim 15° angled open end to reach fasteners in tight positions and the 12-point ring end for safer rotation and reduced fastener wear. Inspect the wrench before use for damage or excessive wear and avoid using the tool as a hammer or pry bar.

Usage recommendations

For safe and effective use, maintain the chrome micro-matte surface by wiping clean after use and storing in a dry place. Use the ring end for initial loosening or final tightening to minimise rounding of fastener corners, and reserve the open end where access is limited. Do not exceed intended manual torque; use appropriate-sized tools if higher torque is required.
