Open-end wrench Kuźnia Sułkowice 17×19 mm model 1-131-40-101

Open-end wrench Kuźnia Sułkowice 17×19 mm model 1-131-40-101 is a two-jaw hand tool designed for tightening and loosening hexagonal nuts and bolts with 17 mm and 19 mm widths across flats. Manufactured as a single-piece open-end spanner, it provides a compact profile that fits in tighter spaces than box-end wrenches and is suitable for mechanical, automotive and household repair tasks that require medium-size fastener engagement.

Advantages

The open-end wrench is made in one solid piece to offer consistent torque transfer and reduced risk of joint failure. Its two fixed jaw sizes eliminate the need to switch tools frequently when working with adjacent fasteners sized 17 mm and 19 mm. The slim head allows access in confined areas, while the flat handle provides a stable grip and improved control during turning. The tool’s durable metal construction ensures resistance to bending and wear under normal working loads.

Suitable for

• Automotive repairs and maintenance where medium-size nuts and bolts are present
• General mechanical assembly and disassembly tasks
• Home and DIY repairs involving plumbing fittings, furniture fasteners, and appliances
• Field service work where a compact, reliable open-end wrench is needed

Key specifications

• Jaw sizes: 17 mm and 19 mm
• Tool type: open-end wrench (two fixed open jaws)
• Construction: single-piece metal design for strength and durability
• Intended use: manual tightening and loosening of hexagonal fasteners
• Profile: slim head for access in confined spaces

How to use

Select the jaw size that matches the nut or bolt head and place the open jaw fully onto the fastener flats. Apply steady, controlled force to turn the wrench and avoid sudden impacts or excessive leverage that could deform the fastener or tool. When working in tight spaces, position the wrench so the handle has room to move through its required arc. After use, keep the wrench clean and store it in a tool roll or box to prevent surface corrosion and maintain fit accuracy.

Usage recommendations

Use the wrench only for its intended manual applications on properly sized hexagonal fasteners; do not use as a hammer, pry bar, or with cheater bars for increased leverage. Periodically inspect the jaws for rounding or wear and replace the tool if deformation is present to avoid slipping and fastener damage.
