Hex key Proline 48572 — metric 8 mm, single-piece L-shaped Allen wrench

Proline 48572 is a single-piece metric hex key with an 8 mm size, formed into a classic L-shaped Allen wrench. Made from quenched and tempered steel and finished with polished chromium, this tool is intended for driving hexagonal socket screws and bolts. The compact L-shape provides two working lengths to access recessed fasteners or apply greater leverage when tightening or loosening connections in furniture assembly, machinery maintenance, and everyday workshop or household tasks.

Advantages

The one-piece construction ensures reliable torque transfer without joint play, while the quenched and tempered steel delivers strength and resistance to bending. The polished chromium finish helps protect the surface from corrosion and provides a smooth feel when handled. Two usable arm lengths allow for versatile access to tight spaces or increased leverage, and the straight chamfered tip fits hex sockets precisely for reduced rounding of screw heads.

Suitable for

• Assembling and disassembling flat-pack and wooden furniture
• Adjusting machinery and equipment with metric hex fasteners
• Repair work on bicycles, appliances, and small engines
• General workshop and household maintenance tasks

Key specifications

• Hex size: 8 mm
• Design: L-shaped, single-piece
• Material treatment: quenched and tempered steel
• Surface finish: polished chromium
• Tip: chamfered for precise fit

How to use

Select the 8 mm end that best fits the hex socket of the fastener and insert the tip fully into the recess to ensure a snug engagement. Use the short arm for higher torque applications and the long arm for reach or increased leverage. Apply controlled force to avoid over-torquing; reverse the direction to loosen fasteners. Keep the tool aligned with the fastener axis to minimize cam-out and avoid rounding the screw head.

Usage recommendations

Store the hex key in a dry place and wipe off grease or debris after use to preserve the polished chromium finish. For high-torque industrial applications, inspect the tool periodically for wear or deformation and replace if edges become rounded. Use appropriate protective equipment when working with moving machinery or heavy components.
