Frequently Asked Questions (FAQ)
- What materials are used to manufacture this striking ring wrench? – We primarily use high‑strength alloy steel (such as 40Cr) with heat treatment for optimal hardness. For explosive environments, we offer non‑sparking copper‑beryllium options.
- What sizes are available? – Standard sizes range from 1‑1/2" to 4‑1/2" (across flats). Metric sizes from 36mm to 115mm are also available. Custom sizes can be produced upon request.
- Is this wrench suitable for use in hazardous areas? – The standard steel version is not intrinsically non‑sparking, but we can supply a non‑sparking variant made of beryllium copper for use in explosive atmospheres (please specify when ordering).
- Can I use a regular sledgehammer with this wrench? – Yes, the striking ring is designed to accept strikes from standard sledgehammers. For consistent impact, we recommend a hammer weighing 4–8 lb.
- How do I prevent the wrench from slipping off the nut? – Our wrench features precision‑ground jaws that fit snugly on hex nuts. Always ensure the size matches the bolt flat‑to‑flat dimension. A shearing pin (optional) can be added for extra retention.
- Do you offer a warranty? – We provide a comprehensive warranty against manufacturing defects. Contact our sales team for specific terms based on your order quantity.
- What is the typical lead time? – For standard sizes, lead time is 15–25 working days. Custom orders may require 30–45 days. Stock items may be available for immediate shipment.
