Hex Large Flange Nuts

To install hex large flange nuts, place the flange against the surface and tighten with a wrench. The flange self-aligns on uneven surfaces, reducing gaps. Use a torque wrench for heavy loads to avoid stripping threads. 

Product details and parameters

Hex large flange nuts produced by Xiaoguo® are heavy-duty fasteners with a wide, flat base (flange) built into the nut. This flange acts like a built-in washer, spreading pressure to protect surfaces and reduce loosening from vibrations. Made from stainless steel, or coated alloys, they’re used in construction, automotive, or industrial setups where bolts face heavy loads or shaky conditions. The hex shape fits standard wrenches, and the large flange skips the need for separate washers.

Check hex large flange nuts for rust or bent flanges periodically. For salty environments, pick stainless steel.Reuse them if threads are clean, but replace cracked flanges. Avoid over-tightening to prevent warping softer materials.

Hex large flange nuts are great for spreading out pressure and preventing dents in surfaces. Their big flat edges act like a cushion, so you don’t get those ugly indentations when tightening. The hex shape means you can use regular wrenches,no special tools needed.Some versions have a rough, serrated edge under the flange that bites into smooth materials, keeping things extra secure. They are bulkier than regular nuts, but eliminate the need for washers.

Why They Beat Standard Nuts

Hex large flange nuts have the function of fixing bolts and protecting surfaces. No additional washers are required, and the flange inside prevents gear shaking. The cost is a little higher than ordinary nuts, but it saves time (no washer lost).
