Bolts are used to join pieces together either permanently or temporarily. Many steel structures, including buildings, are simply bolted together. For example, the Eiffel Tower in Paris was originally a temporary structure and after twenty years it was to be dismantled. For this reason most of the steel components were bolted together.

Nuts and bolts can also be used to fix together small structures such as furniture.

Nuts and bolts come in many different types and sizes, as some of them shown below.

Coach Bolts with Square Flat Nut

Bolts have a square collar under the domed head and this locks into the wood when the nut is tightened. A washer is normally placed before the nut to stop it from sinking into the wood as it is turned.

Machine Bolt with Hexagonal Nut

Two spanners are needed to tighten this nut and bolt. The first spanner fits around the hexagonal head of the bolt and a second spanner is used to tighten the hexagonal nut. The countersunk machine screw fits level with the surface of the wood/metal/plastic. A screwdriver is used to keep the bolt still, whilst the wing nut is tightened by hand. Counter sinking can be done with ordinary wood screws also.

Machine Screw Countersunk Head with Wing Nut

The countersunk machine screw fits level with the surface of the wood/metal/plastic. A screwdriver is used to keep the bolt still whilst the wing nut is tightened by hand. Countersinking can be done with ordinary wood screws also.

Machine Screw round head and plain washer

A plain washer prevents the nut sinking into the surface of the wood/plastic/metal.

Machine Screw Pan head & Spring Washer

A spring washer is used in case there is a need to prevent a nut and bolt loosening

Rapeseed/Casting Mould Oil is developed to be used as lubricant and mould release agent at the process of Steel Continuous Casting. The product is non-toxic and is not harmful for human nature and the environment.

Advantages

Our Product provides you the benefits of using our Oil at the Steel Plant:

• Rapeseed/Casting Mould Oil forms a very strong lubricating layer between solidifying metal and mould guaranteeing prevention of both metal and mould surface.
• Rapeseed/Casting Mould Oil increases the life of mould about 30%.
• Rapeseed/Casting Mould Oil forms a good lubricating film on the surface of mould not allowing solidifying metal adhesion to the mould.
• The vapor formed during casting is non-toxic and irritating.
• Rapeseed/Casting Mould Oil provides easy and fast solidification of metal by providing high rate heat removal from metal.
• Rapeseed/Casting Mould Oil gives ver y good performance at elevated temperatures with the aid of its well selected additives.
• Rapeseed/Casting Mould Oil increases the quality of metal surface.

It is used to supply oxygen at high pressure to the tap hole of furnace to start the flow of molten metal. Designed and manufactured in line with international quality standards using quality-approved mild steel, this pipe resists bending under high temperature. As per the varied needs of clients, this Ms Oxygen Lancing Pipe is available with us in various lengths and diameters.

Function

Gas purging/powder injection is a key part of the steel refining process. The introduction of alloys or treatment agents by this means ensures faster assimilation and maximum efficiency of the process. In the case of gas purging the process is essential for temperature and compositional homogenisation before casting. PRATIGYA M.S. Oxygen Lances have a reputation for reliability and consistency.

Benefits

• Suitable for high pressure without leakage
• Oil & dust free
• Corrosion and oxidation resistance
• Stable mechanical properties
