Hook Wrench with Pin Beta Tools BE99ST/35-50, adjustable 35–50 mm, articulated joint

Beta Tools hook wrench BE99ST/35-50 is a professional hand tool designed for turning and holding circular fittings such as retaining rings, collars and similar round components. The tool features an articulated joint and a locking pin that secures engagement, and its adjustable range covers diameters from 35 to 50 mm. Constructed for workshop and maintenance use, the wrench provides a stable hooked jaw contact and controlled torque transfer for assembly and repair tasks.

Advantages

The articulated joint improves access in confined spaces and allows the hooked jaw to align with the workpiece for a secure grip. The integrated locking pin ensures the selected opening remains fixed during use, reducing slippage and the need for frequent readjustment. Built from hardened tool steel with a machined hook profile, the wrench offers consistent contact on round surfaces and reliable mechanical performance in repetitive maintenance tasks.

Suitable for

• Turning and holding retaining rings and collars with diameters between 35 and 50 mm
• Maintenance and repair work in mechanical workshops and industrial equipment servicing
• Assembly and disassembly of round components where a controlled, non-marring engagement is required

When it may not be suitable

This hook wrench is intended for round components within the 35–50 mm diameter range; it is not suitable for significantly smaller or larger fittings. It is designed for mechanical engagement on round profiles and may not perform correctly on irregularly shaped, threaded, or hexagonal fasteners.

Key specifications

• Adjustable diameter range: 35–50 mm
• Articulated joint for angled access
• Locking pin to hold selected opening
• Hooked jaw for stable engagement on round surfaces
• Hand tool intended for manual torque application

How to use

Select the approximate opening by moving the articulated joint and set the locking pin to hold the chosen position. Place the hooked jaw onto the round fitting so the hook contacts the profile and the pin prevents slippage. Apply steady manual torque in the required direction while maintaining alignment of the hook with the workpiece. After completing the operation, release the locking pin and fold or readjust the wrench as needed for storage or the next task.

What to consider before purchase

• Confirm the diameter of the fittings you will work on fall within the 35–50 mm range
• Check access and clearance at the worksite to ensure the articulated joint provides necessary reach and angle
• Consider the requirement for non-marring contact; verify the hooked jaw profile suits the component material and finish

Usage recommendations

Use steady, controlled force and keep the hook aligned with the component to avoid slipping. Inspect the tool before use for any wear or damage to the hook and locking pin. Store in a dry place to prevent corrosion and maintain consistent performance.
