Heavy Duty Hexagonal Nut

The Heavy Duty Hexagonal Nut with washer is pretty important for automotive chassis and engine mounting. It locks things in place steadily and keeps them from shaking too much. The washer that’s built right in spreads out the clamp load well. We offer good prices for car manufacturers—order over 20,000 units, and you’ll get a 5% discount. They’re zinc-plated to keep rust off, and we ship them by ground freight because it’s cost-effective. They come in tough, stackable cartons to protect them from moisture and physical damage. Every one with washer goes through torque-tension testing, and it’s certified to meet automotive quality standards.

For aerospace use, high-strength Heavy Duty Hexagonal Nuts with washers are used in airframes and control system linkages. Most of these nuts have a counterbore and a captive washer—they’re made from steel and cadmium-plated so they work well at high temperatures. Our pricing is set up for aerospace contractors, and we give discounts for long-term agreements. They have a specific hexagonal shape and a cadmium finish. We use specialized logistics that’s fast. The packaging is tough and meets aviation requirements. Every one with washer goes through strict fatigue testing, and it meets AS9100 or other similar aerospace standards.
