Frequently Asked Questions
Q: What sizes does this L-shape square head wrench come in?
A: The wrench is available in seven sizes: 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, and 10mm. Each size corresponds to a specific square-drive fastener dimension, so be sure to measure your screw head before selecting your size.
Q: What material is this square head wrench made from?
A: It is made from chromium vanadium (CrV) steel — a high-strength alloy widely used in professional hand tools for its excellent toughness, hardness, and resistance to wear and corrosion.
Q: Is this wrench suitable for metal fasteners?
A: Yes. This wrench is specifically designed for use on metal square-head screws and fasteners, making it ideal for mechanical assembly, equipment maintenance, and general DIY metalwork tasks.
Q: How is the L-shape design beneficial?
A: The L-shape provides two usable ends — a short arm for initial engagement and a long arm for applying greater mechanical leverage. This dual-end configuration speeds up fastening and allows you to work efficiently in both open and confined spaces.
