Frequently Asked Questions
What makes a wrench non-sparking?
Non-sparking wrenches are made from copper-based alloys such as beryllium copper or aluminum bronze, which significantly reduce the risk of sparks when struck against steel or other hard surfaces. This makes them essential in flammable or explosive atmospheres found on tankers and gas carriers.
Can a non-sparking striking wrench be used with a hammer?
Yes, these striking wrenches are specifically designed to be struck with a hammer. However, because copper-based alloys are softer than steel, the wrench can deform over time. Inspect it regularly for wear, burrs, or cracks, and replace it if damaged.
Why choose a 12-point ring wrench?
A 12-point ring wrench has contact points arranged in pairs, which helps grip the fastener securely and allows the wrench to be repositioned in increments of 30 degrees. This is especially useful in confined spaces where rotating a standard wrench is not possible.
How should I maintain non-sparking wrenches?
Clean them after each use and wipe with a light oil to prevent corrosion. Avoid exposure to excessive heat or harsh chemicals, and check regularly for cracks, burrs, or excessive wear. Replace any damaged tool immediately to maintain safety.
