Hand Tool AWTools AW40005 — 400 g weight

AWTools AW40005 — 400 g weight is a compact hand tool made of chrome-vanadium (CrV) tool steel, intended for general-purpose use in workshop and home environments. The tool is drop forged, hardened and tempered to provide strength and durability while remaining manageable at a moderate weight of around 400 g. A satin finish reduces slippage and the double-sided box end ring design allows access in confined spaces with clear size markings for quick identification.

Advantages

The chrome-vanadium construction and heat treatment ensure resistance to wear and deformation under typical torque loads. The satin finish improves grip and reduces reflective glare, while the double-sided box end ring offers secure engagement with fasteners and versatility when working in tight or awkward positions. Clear size markings speed up tool selection and handling during maintenance tasks.

Suitable for

• Loosening and tightening bolts and nuts in tight spaces
• Routine workshop maintenance and repair
• Home DIY projects requiring a durable hand tool
• Use by both amateur and professional users

Key specifications

• Material: chrome-vanadium (CrV) tool steel
• Manufacturing: drop forged
• Heat treatment: hardened and tempered
• Finish: satin finish to reduce slippage
• End type: double-sided box end ring
• Weight: approximately 400 g

How to use

Select the appropriate size on the double-sided box end ring that matches the fastener. Position the boxed end fully over the nut or bolt head to ensure a secure fit before applying force. Use controlled, steady pressure and avoid sudden impacts; the tool is designed for manual torque application. When working in confined spaces, use the slim profile of the box end to access recessed fasteners and rotate in short arcs if clearance is limited.

Usage recommendations

Inspect the tool before use for any visible damage or wear. Keep the satin finish clean and free of oil or debris to preserve grip. Apply appropriate manual torque and avoid using the tool with power impact devices. Store in a dry place to prevent corrosion and periodically check the marking legibility for quick selection during jobs.
