This is an adapter for converting the size of parallel screw holes. It allows for size reduction by inserting it into existing screw holes.
Since it has a hexagonal head type, it can be easily tightened with a wrench or similar tool. Additionally, by using hex nuts and spring washers, it can also be installed on thin plates (with round holes).
![Non-treated bolts [Contributing to a decarbonized society]](https://image.www.ipros.com/public/product/image/2cc/2000799595/IPROS76745102935338841948.jpeg?w=280&h=280)
Achieve CO2 reduction and cost reduction simultaneously. The CO2 reduction effect during production is up to 78%!
This is a non-heat-treated bolt suitable for a decarbonized society that allows for consideration of the global environment just by using it. By omitting the heat treatment, which requires the most energy during manufacturing, we are reducing CO2 emissions in the production process. Additionally, by eliminating the bending that occurs during quenching, we can skip the straightening process required for long bolts. This also achieves cost reduction by removing the bending correction process. Regarding the crucial aspect of strength, when used in high-strength applications, it shows improved delayed fracture characteristics compared to conventional heat-treated bolts. *For more details, please check the materials from "PDF Download" or feel free to contact us.*
The shape memory alloy cylinder extends and breaks the bolt! It is possible to conduct tests multiple times.
"Frangebolt" has been a product used in various satellites for many years since it was adopted by the Clementine observation satellite in 1994. It is a non-pyrotechnic device that uses a shape memory alloy (SMA) cylinder to extend and break the bolt. Due to its simple structure, it can be reset on-site up to 60 times, allowing for multiple tests to be conducted in the ground space before flight. 【Features】 ■ Used in various satellites for many years ■ Non-pyrotechnic ■ Simple structure ■ Can be reset on-site up to 60 times *For more details, please refer to the PDF document or feel free to contact us.

Improved reliability and workability through prevention of loosening with high tightening force.
Hex socket bolts (caps) are generally used without being paired with nuts, so referring to them as screws is more accurate. However, since the name hex socket bolt has become widespread, they are also called cap bolts. The applicable strength grades are 10.9 and 12.9. They are tightened with a hexagonal rod wrench (with a maximum neck length of 1,000 mm). *For urgent or emergency situations, or for technical inquiries, please contact us directly through our website.

Customization to special shapes with unique dimensions for length and thickness, as well as changes to the head shape, is possible. ◎ Various stainless steel bolts can also be manufactured according to your requests. 【Features】 ■ Manufactured under strict quality control with extensive experience in all processes ■ Customization to special dimensions and shapes is possible ■ The range for rolling is wide, from small diameters to large diameters (with a maximum under-head length of 1,000mm possible) *For urgent or emergency inquiries, or for technical questions, please contact us directly through our website.
![[Product Catalog] Trapezoidal Screw Bolt for PC Sleepers](https://image.www.ipros.com/public/product/image/ccc/2000246951/IPROS4948437214390291289.jpg?w=280&h=280)
Excellent strength! Customizable screw bolts available.
The "PC sleeper trapezoidal screw bolt" is a bolt that fastens the rail to a sleeper embedded with a synthetic resin plug that serves as a female thread, using a spring. Our company manufactures the threaded part of the bolt using a hot-rolled rolling method. As a result, unlike cutting methods, the fiber structure of the steel material is maintained without being severed. It has been adopted in many newly constructed Shinkansen lines, including the Sanyo Shinkansen. 【Features of the Hot-Rolled Rolling Method】 - Superior strength due to the intact fiber structure - High precision with no eccentricity - Suitable for mass production - Custom products for various shapes and trapezoidal threads are available - Machining of special steel and stainless steel threads is also possible *For urgent or emergency inquiries, please contact us through our website for technical questions.
