FAQ

Q: What precautions should you take when using an ER spanner?

A: Avoid using it as a hammer or pry bar, as this can damage the tool. Ensure the jaw size fits the nut or bolt head snugly before applying pressure to prevent slipping and rounding of the edges. Also, don't overextend the wrench's capacity—using a pipe for added leverage can break the wrench or cause injury.

Q: How can you prevent an ER spanner from slipping?

A: How do I ensure the adjustable wrench doesn't slip during use? To prevent slipping, ensure the wrench fits snugly around the fastener, align it properly, and periodically check the grip during use. Avoid applying sudden or excessive force.

Q: How do you adjust a ER spanner?

A: Adjusting the ER spanner is simple, and usually involves turning a screw (often known as a worm screw) mounted on the side/base of the spanner head. Sometimes the worm screw is located at the top of the handle, where it meets the lower or heel jaw.

Q: Do you have a minimum order quantity?

A: Traditional products do not. The minimum order quantity for non-standard products is 50 pieces.

A: T/T, PayPal, Western Union, etc.
