IMPA: 612431-612432

Impact Screwdrivers (Hammering Type) for Marine Use

Our impact screwdrivers, also known as hammering screwdrivers, are essential hand tools for shipboard maintenance and repair. Designed to tackle stubborn, frozen, or corroded screws, they deliver a sudden, forceful impact to the screw head when struck with a hammer, effectively breaking the bond of rust or thread-locking compounds. This makes them indispensable for marine engineers and technicians working in harsh saltwater environments where fasteners are prone to seizing.

Available in two variants under IMPA codes 612431 and 612432, each screwdriver comes with interchangeable bits that allow for both left-hand (loosening) and right-hand (tightening) rotation. Sourced by ship chandlers and purchasing officers worldwide, these tools are priced individually per code, ensuring you can order exactly the variant you need for your vessel's toolkit. Trusted for durability and performance, they are a reliable addition to any ship's workshop.

Frequently Asked Questions

What is an impact screwdriver used for?

An impact screwdriver is used to loosen screws that are stuck due to rust, corrosion, or overtightening. When struck with a hammer, it converts the impact into a sudden rotational force, helping to break the screw free without damaging the head.

How do I use an impact screwdriver?

Select the appropriate bit, insert it into the screw head, and set the direction (left for loosening, right for tightening). Hold the tool firmly and strike the end with a hammer. The impact will rotate the screw slightly, breaking the bond.

What are the IMPA codes for these screwdrivers?

The IMPA codes are 612431 and 612432. They represent two different variants, likely differing in size or bit configuration. Each is ordered separately.

Are these screwdrivers suitable for marine use?

Yes, they are specifically designed for marine environments where screws often seize due to saltwater corrosion. The impact mechanism is effective on rusted fasteners.
