Water supply and gas fitting parts "Insulation Bolt Type TS"

Tomoe's insulating bolts demonstrate their power in joining various dissimilar metals!

When dissimilar metals are joined together in the ground, a potential difference occurs between them, and current flows through the bolts, causing the less noble metal to corrode. By using Tomoe's "Insulated Bolts and Nuts," the areas between flanges and between flanges and bolts/nuts are electrically insulated, preventing electrolytic corrosion. Stainless steel is treated with a dry seizure (galling) prevention coating called "TOM Coat" on the threaded parts of the nuts. Additionally, various steel types can be treated upon request. If you are experiencing issues with galling, not limited to insulated bolts, please consult us. 【Features】 - Uses epoxy resin boards with glass cloth and PTFE sleeves or FEP shrink tubes → Provides high insulation resistance and excellent weather resistance and mechanical strength - Bolt and nut materials include stainless steel, ordinary steel, and high-tensile steel → Can be selected according to application - The outer diameter of the insulating sleeve is almost equal to the outer diameter of the screw → No need to process the bolt hole diameter of the flange - Uses sleeves instead of paint as insulating material → No peeling and no pinhole issues - Made to order, allowing for production in desired dimensions For more details, please contact us or download the catalog.

Plastic screw/bolt/nut

Excellent strength! Insulation! Lightweight! Plastic screws/bolts/nuts.

Plastic screws have high electrical resistance and excellent insulation properties. By using plastic screws with superior insulation, it is possible to prevent short circuits. ● Lightweight: Plastic screws are very lightweight, making them suitable for products and equipment where weight reduction is necessary. ● Electrical Insulation: Plastic screws have high electrical resistance and excellent insulation properties. By adopting plastic screws with superior insulation, it is possible to prevent short circuits. ● Strength: Screws made of high-strength materials like PPS and RENY offer greater strength, allowing for reduced screw diameter and fewer screws, leading to space-saving designs. ● Heat Resistance: Materials such as PPS, PEEK, and PTFE have heat resistance temperatures above 200°C, providing stable performance even under harsh temperature conditions. ● Thermal Insulation: Plastic screws have low thermal conductivity and excellent thermal insulation properties. They can prevent localized condensation due to thermal bridges. Efficient thermal management can be achieved in the design of equipment and devices where temperature control is critical. ● Corrosion Resistance: Plastic screws do not rust or corrode, providing excellent resistance to moisture and chemicals.

P.C. Tie Rod Trapezoidal Screw Bolt / Joint Plate Bolt and Nut 【*Prototype OK】

Many successful applications in Shinkansen! Higher strength than cutting processing, and capable of mass production as well as custom orders! We also offer prototyping, so please feel free to consult with us.

♦P.C. Tie Rod Trapezoidal Screw Bolt♦ The "trapezoidal screw/bolt" for concrete ties is manufactured using the "hot-rolled rolling method," which offers superior strength compared to cutting processes. It has already been successfully used in numerous instances in the Shinkansen maintenance and can also be used for securing parts of civil engineering, such as the hanging sections of concrete walls in underground areas. ★Please feel free to consult us regarding other applications or prototypes. We also design "male threads." 【Features of the Hot-Rolled Rolling Method】 - Maintains the fiber structure of the steel, providing excellent strength - High precision with no eccentricity - Suitable for mass production - Custom products for irregular/trapezoidal screws are also available ♦Connection Plate Bolt and Nut♦ Standard steel connection plate bolts and heat-treated connection plate bolts. 【Features】 - Heat-treated connection plate bolts are produced in three grades: 5.6, 8.8, and 10.9 - Obtained JIS display permission (certification) ◆Prototype Forged Parts◆ If you provide us with drawings, we can design and prototype molds regardless of quantity! This allows for rough processing through forging, not only for bolts but also for complex shapes or when you want to reduce excess material in lathe processing. *For more details, please contact us or refer to the catalog.*

吊りボルト専用脱落防止ナット 「マッスルナット」

シングルナットで、単体の取り付けで緩み止め&脱落防止が可能

吊りボルト専用脱落防止ナット「マッスルナット(赤色チューブ)」は、脱落しません。 一般的な吊ボルトは、JIS規格ではなく、施行性や大量使用用途に向けたコスト面重視のため、 ボルトねじ有効径が細くなっています。そのため、市販のナットでは強く締めても振動等に耐えられず緩んで脱落してしまいます。 その緩みを解消するため、吊ボルト専用のマッスルナットを開発しました(六角ボルトのW3/8、W1/2には使用できません)。 締付けは施行性を良くするため、手でも締められるよう緩めにしてあります(それでも緩めトルクは、W3/8で4.5N・m以上です)。 また、マッスルナットは締付け途中で止めておくことも出来ます。 高所での利用を考慮し視認性を良くするため、赤色チューブを使用しています。 詳しくはカタログをダウンロードしてください。

Hard rock nut / hard rock bearing nut

HLN (Hard Lock Nut) / HLB (Hard Lock Bearing Nut)

The Hard Lock® nut, born in Japan and growing globally, possesses a strong anti-loosening effect not found in other lock nuts, along with excellent workability and ease of attachment and detachment. Could the principle of a wedge be applied to prevent loosening? This theme was tackled, and after repeated trial and error, the Hard Lock nut was completed.
