Top 12 Weld Nuts

A weld nut is a special nut that is designed for welding itself to another object. Most of these nuts are made from carbon steel or stainless steel. If the nuts are made from carbon steel, then a zinc plate can provide a high corrosion resistance degree.

Weld Nuts Buying Guide

A handful of bolts gain their strength using a heat-treating method, and the addition of heat during the welding process can alter the properties. Some low graded ones are easily welded when they are manufactured with weldable steel. Weld nuts play a significant role in welding. Different weld nuts are used for various purposes, such as base nuts, tab base nuts, slab base nuts, hex & square nuts, retainer nuts, and more. Both enthusiasts and professionals should know about the various kinds of weld nuts and the welding processes. This is a buying guide that explains everything one needs to know about welding nuts.

Requirements for joining weld nuts

The maximum rating that is printed on the welding machines' nameplates is the current level that is needed for the creation of a weld. Small weld nuts may require currents between 5,000 to 15,000 amperes, while the more giant weld nuts may need between 15,000 to 25,000 amperes. Large ring projections may require as much as 75,000 amperes. When someone is resistance welding, the time is divided between squeeze time, hold time and weld time. The time is considered in cycles. Small fasteners require 3-10 cycles while the larger ones need 10-20 cycles.

Tab Projection & Spot Weld nuts

Tab projection nuts are ideal for heavy gauge sheet metals and curved surfaces. These weld nuts have a robust single projection that makes penetrating and robust welds. Tab spot weld nuts are appropriate for limited space applications. They have a tab containing different sized electrodes and are designed to be spot welded on flat surfaces.

Hex & Square Projection Weld Nuts

Hex nuts provide better performance for heavy-duty and industrial applications as one can apply higher torque to these weld nuts than other non-welded ones. Square projection nuts contain four uniform projections for more excellent welding quality, ensuring reliable and robust welds with correct placements.

Round & Flanged Weld Nuts

Round weld nuts have accurately placed projections for a durable weld and are suited for orientation or restricted space applications. Flanged weld nuts have projections at three different points that create a strong joint without affecting the component surfaces.
