Wrench, NEO tools flat open-ended 17 x 19 mm (model 09-817)

Flat open-ended wrench by NEO tools with 17 mm and 19 mm jaw sizes designed for engaging hexagonal nuts and bolts. The single-piece steel construction delivers direct torque transfer for manual tightening and loosening in automotive, mechanical and household applications. Its compact, flat profile gives access in confined spaces and makes it suitable for maintenance and workshop use where a slim tool is required.

Advantages

The flat open-ended design provides two common metric sizes in one tool, reducing the need to switch wrenches during routine tasks. Hardened steel construction ensures durability and wear resistance under repeated use. The slim heads and straight handle allow access to tight or shallow fastening points, while the one-piece manufacture improves strength and reduces wobble when applying torque. The wrench is lightweight, easy to store, and compatible with standard hex fasteners.

Suitable for

• Automotive maintenance and repairs
• Mechanical assembly and disassembly
• Plumbing and household repair jobs
• Workshop and professional service tasks
• Accessing fasteners in narrow or shallow spaces

Key specifications

• Jaw sizes: 17 mm and 19 mm
• Tool type: flat open-ended wrench (double-ended)
• Material: hardened steel construction
• Design: single-piece, flat profile for confined access
• Drive type: manual hand tool for hexagonal nuts and bolts

How to use

Select the appropriate jaw size (17 mm or 19 mm) that matches the nut or bolt head. Position the open end fully onto the hex fastener, ensuring full contact on opposing flats to minimize rounding. Apply steady, controlled force in the required direction to tighten or loosen the fastener. For access in restricted spaces, orient the flat profile so the handle clears nearby obstacles. Avoid using the wrench as a hammer or with cheater bars to prevent tool damage and reduce risk of fastener rounding.

Usage recommendations

Use the wrench within its intended manual torque range, keep contact surfaces clean to ensure full seating on fasteners, and store in a dry place to prevent corrosion. Inspect regularly for wear or deformation and replace if jaws are rounded or the handle is bent.
