Frequently Asked Questions
Q: What sizes are included in this open end wrench set?
A: The set includes four ultra-thin double-end open wrenches in the following sizes: 30mm, 32mm, 36mm, and 40mm. Since each wrench is double-ended, you effectively have access to 8 size combinations across the 4 tools.
Q: What makes this wrench set "ultra-thin" and why does it matter?
A: The ultra-thin flat profile means each wrench has a significantly reduced head thickness compared to standard open-end wrenches. This allows the tool to fit into tight, confined spaces — such as behind pipes, inside machinery housings, or between closely spaced components — where a conventional wrench would not clear.
Q: Is this wrench set suitable for both professional and DIY use?
A: Absolutely. The SAMMY Ultra-Thin Open End Wrench Set is designed to meet the demands of professional tradespeople as well as dedicated home DIYers. The large size range (30–40mm) makes it especially useful for heavy-duty plumbing, industrial fasteners, and appliance repair tasks.
Q: Are these wrenches suitable for use on metal bolts and nuts?
A: These wrenches are rated as suitable for non-metal applications per the product specifications. For metal fasteners, please verify the hardness rating of the wrench material against your specific use case before applying heavy torque.
