Compatibility / Fittings

• Compatible with matching female thread wing nuts and any mating part with the same thread size and pitch.
• For best fit, match bolt thread diameter and pitch to the existing insert/nut.

Installation & Tips

• Confirm thread size and pitch before use to avoid cross-threading.
• Hand-tighten first, ensuring the bolt turns smoothly; stop if it binds.
• For higher clamp loads, use a washer under the bearing surface to protect the material (washer size: match thread).
• Do not overtighten by hand; recommended torque: Not specified.
• If used in damp areas, consider stainless alternatives as zinc plating is not a guarantee for outdoor corrosion protection.
