Stainless Steel DIN557 SS304 SS316 M5-M20 Square Nuts

Stainless Steel DIN557 SS304 SS316 M5-M20 Square Nuts

1.Product Description

A square nut is a four-sided NUT. Compared to standard hex nuts, square nuts have a greater surface in contact with the part being fastened, and therefore provide greater resistance to loosening (though also greater resistance to tightening).They are also much less likely to become rounded-off after repeated loosening/tightening cycles. Square nuts are typically mated with square-headed bolts. Square nuts are used along with flat washer in order to avoid damage from its sharp edges and helps to increase the strength of the fastener. Square nuts can have standard, fine or coarse threading with platings of zinc yellow, plain, zinc clear, tin and cadmium, among others.

Quartet mother, hardware equipment, fastening accessories. Square shape, internally threaded, may be used in conjunction with the bolt. Also known as the Quartet nut

A weld nut is a nut outer suitable for welding, soldering material is generally made of thick and suitable for welding, soldering is equivalent to two separate parts into a whole, with a high temperature after mixing together the melted metal then cooled, the alloy will join the middle, it is the role of the internal molecular force, the intensity of the general strength than the parent. Experimental welding parameters depends on the size of the weld fusion, fusion adjust the welding parameters according to size until the elimination of defects. Of course, welding and weld quality is good or bad about the pre-treatment, cleaning, oil and the like. These nuts are very similar to standard square or hex nuts, but have four welding projections. Used automotive chassis and steel structures and beams. Square weld nuts feature four precision weld projections located on four angles.Used for construction, building materials, home improvement, mining, transportation, electricity and other industries. Quartet mother belongs nut hardware products, small size, specifications ranging demand. This design allows the fastener attached to the top side of the panel. Four equally spaced projections have the same height and size, allowing a proper balance and positioning of the weld. Welding current level should be large enough to generate the heat required to make the welding spot before bosses flatten. If the welding current is too high splashes of molten occur as a result of the welding current increased density in the contact area and the excessive heating of the molten metal.

Square weld nut is designed for through-hole applications and are not self-positioning, so the need for additional installation or jigging dowel precise location. There is a resistance welding current and pressure are used to bond two pieces of metal approach. Resistance welding force required bonding process. Pressure is used to hold together two pieces of metal, and they are cooled. This also allows for proper metal bonded together. For the joining process required pressure is usually applied manually by the operator or by the machine.

There are a series of square nut thread size, from steel and stainless steel offer, and is suitable for use with compatible panel material. Square weld nut requires appropriate resistance welding equipment accessories. Square weld nut requires appropriate resistance welding equipment accessories.

3.Application

Commonly used in furniture as a blind nut, they are also used in rail channels in order to prevent turning of rail when pressure is applied. They are also used to make perfect foundation in metal channels for hidden fasteners.

4.Advantages

Tighten easily by gripping two sides
Work well in tight spaces by using needle nose pliers
Work well in blind spots using pliers or a wrench
Can be a quick gauge to measure the position of the nut
