AMF Adjustable Hook Spanners – Flexibility and Strength in One Tool

PTI expands its range with AMF adjustable hook spanners  – the ideal tool for tightening or loosening locknuts and bearing nuts of various sizes.

How many wrenches do you need to tighten a nut?
👉 Just one – or the whole set of three – if it’s ours.

The new hook spanners are designed for professionals who value precision and flexibility in their daily work. The adjustable function allows you to use the same wrench for multiple nut sizes – perfect for assembly, maintenance, and machine work.

One wrench, many possibilities

The adjustable design makes your work easier and faster. You no longer need to switch between several fixed wrenches, and the ergonomic shape ensures a firm grip – even under demanding conditions.

These tools are made of high-quality materials and tested for industrial use. AMF’s precision combined with PTI’s technical expertise guarantees a product you can rely on.

Perfect for assembly and precise torque tightening

The hook wrench is equipped with a ½” square drive, allowing it to be used together with a torque wrench or socket wrench – perfect for tasks where precise tightening torque is essential.
For example, when mounting spherical ball bearings on clamping sleeves, this combination provides full control and ensures the correct torque and long service life.
