Nuts
Flange Nuts
Flange nuts from ITA Fasteners possess a few of the defining attributes of a washer. They are used to spread the load evenly to avoid uneven fastening surface of the operations. They also ensure that the fasteners are in place without moving about loosely. These wide flange nuts can be used as a replacement to the nut and washer combination. Therefore, these nuts are a cost-effective and quality substitute for nuts and washers if your project is a large scale one.
Flange weld nut come in varying sizes to allow its use with several bolts, each with different dimensional standards. Another advantage of these nuts is that they prevent the loosening of machining and electrical components while still allowing the free parts to move freely. Striking the perfect balance, in this case, has to be done with careful calibrations. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant.
