Frequently Asked Questions (FAQ)
-
Q: What makes these hex keys non-sparking?
A: The tools are made from aluminum bronze alloy, which does not produce hot sparks when struck against steel. This property is due to the copper content and the absence of ferrous particles that can ignite flammable atmospheres. -
Q: Are these wrenches magnetic?
A: No, aluminum bronze is inherently non-magnetic, making them safe for use around MRI machines, electronic instruments, or magnetic-sensitive environments. -
Q: Can I get custom sizes or branding on the tools?
A: Yes, we offer OEM customization including different hex sizes, metric/inch options, laser-engraved logos, and custom packaging. Please inquire with your specific requirements. -
Q: How should I clean and maintain these tools?
A: Simply wipe with a dry cloth after use. For heavy grime, use mild soap and water, then dry thoroughly. Avoid abrasive cleaners that may damage the surface. Stored in a dry place, they will last for years. -
Q: Are these tools approved for use in explosive atmospheres (ATEX/IECEx)?
A: Our tools are designed to meet the functional requirements of non-sparking standards widely recognized in hazardous areas. Specific certifications can be provided upon request depending on your region – please contact us for details. -
Q: What is the hardness of aluminum bronze compared to steel?
A: Aluminum bronze has a typical Rockwell hardness of B70-90, which is softer than hardened steel but sufficiently durable for driving fasteners. Its toughness and corrosion resistance compensate for lower hardness. -
Q: Do you sell individual wrenches or only the 7-piece set?
A: We can supply individual sizes as well. The 7-piece set is our standard package, but we are flexible to meet your needs. Minimum order quantity may apply for custom sets. -
Q: What is the lead time for an order?
A: For stock items, shipment can be arranged within 3-5 working days. Custom orders usually require 15-20 working days depending on complexity. We will confirm the timeline after order confirmation.
