Frequently Asked Questions
Q: What sizes are included in this L-shape square head wrench set?
A: The set includes 6 wrenches covering the most common square drive sizes: 3mm, 4mm, 5mm, 6mm, 7mm, and 8mm — making it a versatile addition to any toolbox for a wide range of square-head fastener applications.
Q: What material is the square head wrench set made from?
A: All 6 wrenches are forged from chrome vanadium steel, which offers excellent strength, durability, and corrosion resistance for long-lasting everyday use.
Q: What is the difference between a square head wrench and a standard hex (Allen) key?
A: A square head wrench (also called a Robertson or square key) has a 4-point square tip that engages square drive recesses, commonly found in furniture hardware, plumbing fixtures, and certain machinery. A standard hex/Allen key has a 6-point hexagonal tip designed for hex socket screws. The two are not interchangeable, so it's important to match the tool to the fastener type.
Q: Can I use these wrenches on materials other than metal?
A: These wrenches are designed primarily for metal fasteners. While the square tip may physically fit square drives in other materials, the chrome vanadium steel construction and torque capacity are optimised for metal hardware applications.
