Spanner wrench Proline 36144, length 242 mm, single-piece

Proline 36144 is a single-piece spanner wrench with an overall length of 242 mm designed for tightening and loosening nuts and fittings in general mechanical and maintenance tasks. The tool is forged and chromium‑plated with a satin finish and features a ground head and a socket made of 50BV30 steel. The head offers a range of motion of approximately 220° ±5°, allowing access to fasteners in constrained positions. Supplied as a single unit, the spanner wrench is intended for workshop, construction and home repair use.

Advantages

The one-piece forged construction provides consistent strength and reduced risk of joint failure, while the chromium plating protects against corrosion and simplifies cleaning. A satin finish minimizes reflections and improves grip feel. The ground head and 50BV30 socket material ensure accurate seating on fasteners and enhanced wear resistance. The wide head articulation increases versatility when working in restricted spaces.

Suitable for

• Tightening and loosening hex nuts and fittings of compatible sizes
• General mechanical maintenance in workshops and garages
• Construction site assembly and repair tasks
• Home repairs and DIY plumbing or equipment adjustments

How to use

Select the spanner wrench and position the socket over the corresponding nut or fitting. Apply steady manual force to turn the wrench in the required direction to tighten or loosen the fastener, keeping the tool aligned to avoid rounding the fastener edges. Use the head articulation to approach fasteners at an angle when space is limited. Store the tool clean and dry after use to maintain the chromium finish and prevent corrosion.

Usage recommendations

Inspect the contact faces for wear before use and avoid using the spanner on damaged or rounded fasteners. Do not use the wrench as a hammer or pry bar. For high-torque applications, use appropriate torque control methods and consider a larger or calibrated tool if precise torque is required.
