Combination wrench 28 mm PARTNER PA-3028 — open and box end hand tool

The PARTNER Combination wrench 28 mm PA-3028 is a manual open-and-box end tool designed for tightening and loosening nuts and bolts with a 28 mm head. Constructed from steel for reliable strength and torque transfer, this wrench is intended for general mechanical, automotive, workshop and household maintenance tasks where a mid-size spanner is required. The open end allows quick placement on fasteners in tight spaces, while the boxed end provides more contact area for controlled torque application.

Advantages

The steel construction delivers durability and consistent performance under routine loads. Dual-ended design combines the speed of an open spanner with the security of a boxed end, reducing the need to switch tools during common repair and assembly jobs. The 28 mm jaw size matches common metric fasteners used in automotive and machinery maintenance. The single-piece design minimizes flex and improves torque transfer.

Suitable for

• Automotive repairs and maintenance involving 28 mm nuts and bolts
• Workshop assembly and disassembly of machinery and equipment
• Home maintenance tasks that require a mid-sized wrench
• Routine mechanical servicing where both open and boxed ends are useful

Key specifications

• Wrench type: Combination (open and box end)
• Jaw size: 28 mm
• Material: Steel construction for strength and torque transfer
• Ends: Open end for quick access, boxed end for greater contact and controlled torque
• Design: Single-piece hand tool for reduced flex

How to use

Select the 28 mm end that best fits the fastener and position it squarely on the nut or bolt head. Use the open end for quick placement or when working in narrow clearances; use the boxed end when higher torque and full contact are needed. Apply steady hand force and avoid sudden impacts; if additional torque is required, use appropriate extensions or a torque wrench to prevent overtightening. After use, clean off debris and store the wrench in a dry place to maintain condition.

Usage recommendations

Inspect the wrench before use for signs of wear or deformation. Do not use the tool with pipe extensions or cheater bars unless the tool is rated for such loads. For precision tightening, use a calibrated torque wrench and follow manufacturer torque specifications.
