Din 906 Plug Suppliers | Din 906 Threaded Plug Manufacturer

Siddhagiri Metals & Tubes is widely popular as DIN 906 Plug Suppliers all over the globe. We supply DIN 906 Threaded Plugs also known by various names such as Din 906 Socket Screw Plugs, Din 906 Locking Screw Plug, Din 906 Tapered Plugs, Din 906 Hexagonal Sockets, etc.

Stainless Steel DIN 906 Plugs are exclusively used or applicable to seal bore holes or close pipe holes with cylindrical external threads, and hence also known as Din 906 Socket Pipe Plugs. These din 906 plugs are tapered hexagonal socket threaded screw plugs from outside with Allen drive (hexagonal socket drive) at top inner side. Hence also know as Din 906 Hexagonal Socket Plug. This plug has tapered pipe thread all over its length and hence known as Din 906 Tapered Plugs.

Din 906 Plugs are exclusively used to form a seal in pipes and pipe fittings with cylindrical threaded holes which are generally used to carry high pressure fluid, gasses or air within them. The Threaded section of Din 906 Plugs is slightly tapered or conical at one end. When the plug is tightened inside the pipe with appropriate torque using Allen drive wrench or key, the deformation in the threads of plugs creates a tight seal. The tightness of these plugs varies and is dependent on factors like pressure, temperature, medium, and the material used for pairing. Seal coating agents are applied make it even more perfect seal like threaded seal tape also known as Teflon tape, a liquid pipe sealant is applied on threads, etc. DIN 906 Screw Plugs are available in steel and stainless steel A2 and A4 grades with type A (without micro encapsulation) and type GPC (with micro encapsulation). Higher degree of safety is achieved in the design with GPC thread coating.

At our company, Siddhagiri Metals & Tubes, the following sizes of DIN 906 tapered plugs are available for instant shipping from stock with diameters ranging from M8 to M48 in steel and stainless steel A2 and A4. We also provide DIN 906 standard sheet for thread sizes M33x2, M38x1.5, M39x2, M52x1.5, M52x2, M56x2 and M60x2.

Why are these plugs known by various names??

Even if Din 906 Plug is known by various names in the industry, yet they are all same and are used for same purpose that is to create a seal with the pairing material. Below are certain names by which they are known by and a short description defining why that name is affiliated with din 906 plugs

Din 906 Socket Screw Plug - These plugs have body similar to that of screws with socket drive to tighten them with the pairing material to form a tight-seal. Hence they are also known as din 906 socket screw plug.

Din 906 Threaded Plugs - These plugs have body similar to that of screws with pipe threads around it along with socket drive to tighten them with the pairing material to form a tight-seal. Hence they are also known as din 906 threaded plug.

Din 906 Locking Screws - These plugs are attached to one end of pipes, bores or fittings which carry various content (fluids, gasses) within them. These plugs create a locked-seal so there is no leakage of the content which remains well protected inside. Hence they are also known as din 906 locking plug.

Din 906 Screw Plugs - These plugs have body similar to that of screws with socket drive to tighten them with the pairing material to form a tight-seal. Hence they are also known as din 906 screw plug.

Din 906 Socket Pipe Plugs - These plugs have body similar to that of screws with socket drive to tighten them with the pairing material to form a tight-seal. They are used in association with pipes to create seal to stop the flow of content within. Socket format helps to save space and when tightened, the threads create a tight- seal with pipes. Hence they are also known as din 906 socket pipe plugs.

Din 906 Hexagonal Socket Pipe Plugs or Din 906 Hexagonal Sockets These plugs have body similar to that of screws with socket drive to tighten them with the pairing material to form a tight-seal. They are used in association with pipes to create seal to stop the flow of content within. Socket format is in hexagonal shape which is tightened with help of allen wrench. When tightened, the threads create a tight- seal with pipes. Hence they are also known as din 906 hexagonal socket pipe plugs. Or din 906 hexagonal sockets.

Din 906 Plugs- These are used with pipes, bores and fittings to stop the flow of content within by creating a tight-seal. Hence they are known as Din 906 plugs.

Din 906 Tapered Plugs - These plugs have tapered or a conical end which helps the plug to fit within the pairing material, thereby creating a tight-seal. Hence they are known as Din 906 tapered plugs or Din 906 conical plugs.

Mechanical Properties of Din 906 Locking Screws-

Austenitic nature stainless steel is by far the most common type used with strength grades designated by sequence of alphabets with number, for eg- A2.
