The collar provides a larger bearing surface to seat flush in a preformed hole or on the surface of the mating

substrate when fully tightened. The external hexagon drive allows significantly higher tightening torques when necessary. These

plugs are typically used to seal cylindrically threaded holes in pipes and fittings carrying air, gases or fluids under pressure.

Often additional sealing coating such as thread seal tape ("teflon tape"), a liquid pipe sealant applied to the threads, or preapplied sealant is necessary for a perfect seal. Metric DIN 910 hexagon head screw plugs with collar/flange and

cylindrical/straight thread are available in brass, steel as well as stainless steel A2 and A4.

Fasteners are a kind of mechanical parts that are used for fastening connections and are extremely widely used. They are used in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, meters and supplies, etc. You can see all kinds of fasteners, which are the most widely used mechanical basic parts. It is characterized by a wide variety of specifications, different performance and uses, and a high degree of standardization, serialization, and generalization. The DIN 910 Hexagon Head Pipe Plug is one of the most important parts, which can be used with the sealing ring. Their model and material are selected as a function of working conditions (such as pressure, temperature, and fluidity of the threaded part in contact) Wait).
