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.

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)
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.

- Used for spherical joint of TM solid truss that creates ideal space without pillar
- High strength refining of chromium molybdenum steel (SCM 435) and nickel chromium molybdenum steel (SNCM 439) with a new heat treatment equipment
- Special corrosion-resistant treatment is applied so that delayed fracture does not occur
- 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.
