2021 China New Design Metric Coupling Nuts - Carbon Steel DIN 557/562 Zinc Coated Square Nut – Qijing Detail:
What is Carbon Steel DIN 557 Zinc Coated Square Nut?
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)[citation needed]. 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 washers to avoid damage from its sharp edges and 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. Most can meet either the ASTM A194, ASTM A563, or ASTM F594 standard.
Size
product features
Square Nut is equipped with a special wrench to make the bolt produce a huge, with controllable pre-tightening force. Through the nut and the backing plate, the same amount of prestress is generated on the connected parts. Obviously, as long as the axial force is less than the frictional force, the component will not slip and the connection will not be damaged, thus to ensure longer service life for use.
Applications
Square Nut plays a role of fastening connection, which is convenient to use. Because of the proper size and compact design, it can be placed everywhere in order to help release space. Compared with ordinary products on the market, it has a wide application, which can be widely used in construction, machinery, railway, lifting, steel, power plants, ports, metallurgy and many other fields. Plus, our High Strength Square Nut also has the advantages of simple structure, good mechanical properties, disassembly, fatigue resistance, which is a promising connection method. There are various kinds of size options, thus providing more choices to meet need.
Benefits of Square Nuts
▲ Tighten easily by gripping two sides
▲Work well in tight spaces by using needle nosed pliers.
▲Work well in blind spots using pliers or wrench
▲Can be a quick gauge to measure the position of the nut
