Inertia hammer injection pullers NEO tools TOP-11-884 — manual impact extractor for anchored fasteners

Inertia hammer injection pullers NEO tools TOP-11-884 — manual impact extractor for anchored fasteners is a hand-operated tool designed to remove anchored fasteners and injection studs by delivering sudden axial impacts. The device relies on an inertia-driven hammer mechanism to produce short, forceful blows along the bolt or stud axis, enabling extraction without electricity or pneumatic supply. The tool is compatible with standard puller fittings and intended for use in construction, renovation and maintenance where mechanical removal of fixed fasteners is required.

Advantages

The inertia hammer design provides immediate axial blows that reduce the need for excessive torque or cutting, simplifying removal of seized or anchored fasteners. As a manual tool, it requires no external power source and is portable for use in locations without electricity. Compatibility with standard puller fittings and straightforward mechanical operation make it suitable for on-site repairs and retrofit tasks where controlled impact extraction is preferred.

Suitable for

• Removing concrete anchors and expansion bolts
• Extracting injection studs and anchored fasteners in renovation projects
• On-site maintenance where power tools are impractical
• Situations requiring controlled axial impacts to free seized bolts

Key specifications

• Operation method: manual inertia hammer (impact extractor)
• Compatibility: standard puller fittings for anchored fasteners and studs
• Power source: none (hand-operated)
• Intended use: removal of anchored fasteners, injection studs and expansion bolts
• Typical applications: construction, repair, renovation and maintenance

How to use

Fit the extractor to the anchored fastener or injection stud using compatible puller fittings and ensure secure engagement. Position the tool coaxially with the fastener so impacts are delivered along the bolt or stud axis. Operate the inertia hammer by applying the manual striking action as specified by the manufacturer to deliver short, forceful axial blows until the fastener loosens and can be removed. Inspect the puller fittings and the extractor after use and replace worn parts as necessary.

Usage recommendations

Use appropriate personal protective equipment (gloves, eye protection and hearing protection) and ensure stable support for the workpiece. For heavily corroded or damaged fasteners, consider combining impact extraction with corrosion treatment or mechanical pre-treatment to reduce extraction force. Follow the manufacturer's instructions for selecting compatible puller fittings and for safe operation of the inertia hammer extractor.
