Construction

It plays an important role to support the construction industry tomorrow

High-strength hexagon bolts (M12 to M30) that are active in the construction of steel frames and bridges are also one of the main products.
In this way, high-strength hexagon head bolts that correspond to all environments play an important role to support the construction industry tomorrow as parts for construction machinery.

Characteristic

  • Since the special steel material for high-strength hexagonal bolts (Nippon Steel Sumikin Co., Ltd.) such as low carbon manganese, chromium, boron steel, e
  • Quality is stable because we are making integrated production using our bolt former (φ27 mm or less) state-of-the-art equipment.
  • Utilizing many years of hot forging technology, we also manufacture large diameter high-strength hexagon bolts (M33 to M72).
  • We are mass producing products of stable quality by strict lot management (based on JIS B 1186).
  • Regarding standard products, we have plenty of inventory and respond quickly to your order.

High power hexagon bolt JIS B 1186

We manufacture high power hexagon bolts that correspond to every environment. High-strength hexagon bolts (M12 to M30), which are now active in the construction of steel frames and bridges, can also be said to be one of the main products.

High power hexagon bolts (M12 to M30) that are active in the construction of steel frames and bridges are also one of the main products.
High power hexagon bolt is a component for construction machinery and plays an important role to support the construction industry tomorrow.

Long size Headed studs

Headed studs are used as anchor prevention and anchoring of concrete in steel and concrete structures of civil engineering construction. Currently, threaded weld studs are used in fields such as shipbuilding, automobiles, electric boilers, iron sleepers, etc. In particular, application fields of arc stud welding tend to expand further in the future.Our studs use aluminum killed steel.
Through cold forging technology and heat forging technology cultivated in high tension bolt manufacturing, various special shapes can be manufactured. (Maximum neck length up to 1,000 mm is possible)

Characteristic

  1. Plating adhesion amount of bolt · nut and washer is 550 g / m² or more.
    And it is managed on the same basis as the plating adhesion amount of the parts, and it exhibits corrosion protection performance for a long time without maintenance.
  2. In the zinc plating process, avoid pickling as much as possible and prevent ingress of hydrogen. Therefore, there is no worry of delayed destruction.
  3. A special lubrication treatment is applied to the nut, and a stable axial force is guaranteed in tightening by the nut rotation angle method.

For large space construction bolts(TM bolts)

The TM bolts is used for the spherical joint part of TM solid truss (Taiyo Kogyo) that creates an ideal space without pillars.
TM bolts is high strength refined in a new heat treatment facility for chromium molybdenum steel (SCM 435) and nickel chromium molybdenum steel (SNCM 439).
Special anti-corrosion treatment is applied so as to prevent further delayed fracture.
We can handle high quality, high strength and corrosion resistance treatment for bolts of all sizes.
(Maximum neck length up to 1,000 mm is possible)

Characteristic

  1. Used for spherical joint of TM solid truss that creates ideal space without pillar
  2.  High strength refining of chromium molybdenum steel (SCM 435) and nickel chromium molybdenum steel (SNCM 439) with a new heat treatment equipment
  3. Special corrosion-resistant treatment is applied so that delayed fracture does not occur
  4. High quality, high strength, corrosion resistance treatment for bolts of all sizes is possible

Drift pins

Advanced heat treatment technology is required for making drift pins.
If the heat treatment management is insufficient, problems such as chipping of pins and becoming easy to bend are generated.
In addition to excellent heat treatment technology, we have selected strict steel materials and manufactured drift pins.
We have received tremendous trust from all our customers.

For large space construction bolts(TM bolts)

Right and left conflicting threads are cut on the same axis of the bolt.
It is an epoch-making screw which has been considered difficult by the rolling technology in the same rotation direction (manufacturing patent).

It is impossible to rotate this nut in mutual direction with any three dimensional vibration.As long as the two nuts are in close contact with each other, they can only rotate in the same direction, so they come closer to each other.Or tighten the fastening body more firmly.

Characteristic

Right and left conflicting threads are cut on the same axis of the bolt.It is a revolutionary screw that has been considered difficult until now due to the rolling technology in the same direction of rotation (manufacturing patent), which has a big effect on loosening.
