Nut splitter PARTNER PA-6721216 for 12–16 mm nuts

The Nut splitter PARTNER PA-6721216 for 12–16 mm nuts is a handheld mechanical tool intended to cut and remove seized or corroded hex nuts with diameters between 12 and 16 mm. It applies concentrated force to score and split the nut body so the nut can be separated from the bolt without impacting the bolt head. The tool is designed for use in automotive and general mechanical maintenance where typical nut-removal methods are unsuitable or risk damaging fasteners.

Advantages

This nut splitter provides a controlled, localized cut that reduces the chance of damaging the bolt threads and head. Its size range covers common small-to-medium hex nuts used in engines, chassis, and machinery. The tool is compact and simple to operate, enabling access in confined spaces where power tools cannot easily reach. Its mechanical operation requires no electricity or compressed air, making it suitable for field and workshop use.

Suitable for

• Removing seized or corroded hex nuts with diameters from 12 mm to 16 mm
• Automotive maintenance and repair tasks such as wheel hubs, brake assemblies, and engine components
• General mechanical and equipment servicing in workshops and onsite environments

Key specifications

• Nut diameter range: 12–16 mm
• Tool type: manual nut splitter
• Operation: mechanical screw-driven cutting action
• Material: hardened cutting head for scoring nut body (steel)
• Suitable for use in confined spaces where compact hand tools are required

How to use

Position the splitter’s cutting edge against the side of the nut, aligning it so the screw-driven wedge will score the nut body. Tighten the driving screw gradually to advance the wedge into the nut until the nut is split. Once the nut is split, remove the separated pieces and extract the bolt. Inspect the bolt threads and head for damage before reassembly; clean or replace as required. Follow standard safety precautions such as wearing eye protection and gloves while operating the tool.

Usage recommendations

Use the nut splitter on nuts within the specified 12–16 mm range and avoid applying excessive force beyond what is required to split the nut. If the nut is heavily corroded or the bolt condition is uncertain, proceed cautiously and consider thread inspection or replacement after removal. Maintain the cutting edge clean and lightly lubricated to ensure consistent action.
