Square Nut With Large Across Flats

Square nut with large across flats is a heavy duty fastener designed for use in high load environments. Its oversized surface (opposite side) enhances the wrench's grip on the nut and torque control. It is commonly used to secure bolts in construction, machinery or agricultural equipment.

Product details and parameters

Square nut with large across flats can solve the problem of bolt slippage. The extra grip helps remove temporarily replaced round nuts. Keep them in a roadside emergency kit that can be used for trailer hook repairs in a pinch. Apply grease if you want to reuse it later.

Blacksmiths use Square nut with large across flats to forge. This thick steel withstands hammering and can be remolded to fit custom hardware. They can be welded to doors, fireplace tools or decorative metalwork. No other coating is required and you are free to heat treat or color it. Just remove the scale before final installation.
