Next-generation remote bolt axial force monitoring system, InterBolt. It measures bolt axial force in real-time with a precision of 1 kN and automatically sends the data to a cloud server. This IoT smart technology allows monitoring of bolt loosening from anywhere in the cloud. As a result, real-time bolt axial force data can be monitored from anywhere in the world using a computer or smartphone, eliminating the need for operators to be on-site. Axial force measurement data from offshore wind power in Hokkaido can be monitored in an office in Tokyo or even in an office in the United States. InterBolt is equipped with high-precision bolt load sensors. The battery-operated wireless sensor also includes an LED indicator that allows easy color-coded verification of the bolt's axial force status. Data can be sent to the InterBolt gateway for remote monitoring in the cloud or monitored on-site using the InterBolt tablet. It utilizes LoRa wireless communication, eliminating the need for wiring work. <About the bolt axial force monitoring InterBolt> For inquiries such as requests for quotes or materials, please contact us.

A nut that can be tightened with "1/100 of a small torque" without using electricity or air. Even with an M100 bolt, the tightening torque is only 200Nm. It can be tightened with just one torque wrench. A nut that does not loosen due to a patented structure with a special sloped disc. ■ M30 bolt: 1/42 of the standard torque = required tightening torque 30Nm ■ M56 bolt: 1/107 of the standard torque = required tightening torque 80Nm ■ M100 bolt: 1/260 of the standard torque = required tightening torque 200Nm ■ Features of the tension nut When tightening large bolts from M30 to M100, the tightening torque can reach several thousand to tens of thousands of Nm, requiring large hydraulic or electric tools. The tension nut allows for easy tightening of large bolts using only a hand torque wrench by tightening the Hertz screw. No more large tools or equipment are needed. ■ Tension nut that absolutely does not loosen (international patent obtained) The Plarado tension nut is ideal for machines with vibrations due to its anti-loosening effect. The special structure of the "sloped disc" generates higher axial force the more force is applied in the reverse direction that tries to loosen it, resulting in an even tighter fit.

■ Completely prevents bolt rotation with the "Anti-Rotation Zero Friction Washer" Bolt sizes: Compatible with M12 to M72. International patent applied for. ■ Features of the Plarad Anti-Rotation Zero Friction Washer Prevents hex bolt rotation. ■ Unlike washers that utilize surface irregularities from knurled processing for friction resistance, the Zero Rotation Washer has a special structure that changes the equivalent friction diameter, ensuring that the bolt does not rotate. ■ By simply replacing standard flat washers, there is no need for cumbersome bolt anti-rotation tools or backup wrench tools, significantly reducing the time required for bolt tightening operations. Additionally, the bolt tightening task, which previously required two workers to hold the tightening tool and the anti-rotation tool, can now be done by one person, improving labor efficiency. - Strength classification: 8.8 - Material: S45C - Surface treatment: Trivalent chromate finish <For inquiries about the bolt anti-rotation Zero Friction Washer> Please contact us for quotes and information requests.

■ Structure and Non-Loosening Principle of the Strongest Lock Nut "Bolrock Nut" 1. When the nut is subjected to vibration and attempts to loosen counterclockwise, the fine internal balls utilize a clutch mechanism to exhibit a wedge effect, preventing the nut from turning and loosening. 2. The slope angle of the internal balls is designed to be larger than the "screw lead angle," which corresponds to one full turn of the screw. 3. When the nut is tightened, the internal balls automatically move to the deepest part of the groove, aligning the bottom of the nut with the top of the balls, eliminating any gap between them and the floor, thus not affecting the tightening axial force. ■ Vibration Test Condition Data - Bolt Diameter: M16 - Bolt and Nut Material: SCM435 - Frequency: 100Hz - Number of Vibrations: 1,000,000 times - Simultaneous 3D vibration in vertical and horizontal directions While competitor lock nuts loosen after 1,100 to 2,300 vibrations, Plarad's Bolrock Nut has withstood 1,000,000 vibrations, proving its overwhelming vibration resistance. <About the Strongest Lock Nut: Bolrock Nut> For inquiries regarding quotes, requests for materials, etc., please contact us.

- Plarad's digital automatic hydraulic pump has added new features that allow it to save data on bolt tightening torque values and import it to a PC via USB memory. - This automatic pump offers ultra-high precision torque management, allowing the bolt tightening torque to be set in "1Nm increments" using an LCD touch panel. - Instead of displaying pressure, it shows torque (Nm) for each individual serial number of the connected hydraulic torque wrench. - The pump automatically stops when the set torque is reached while tightening the bolt in automatic operation, enabling high-speed continuous operation without interruptions. - All manufacturers' 70MPa pumps have analog hydraulic gauges where each increment represents a pressure of 2MPa. Therefore, the torque conversion tables for hydraulic torque wrenches, which serve as benchmarks, are only issued in torque values that increase in 2MPa increments. Currently, users either set the hydraulic value based on an approximate torque they want for large bolts or ambiguously estimate it at half of the 1MPa increment. [Plarad eliminates this ambiguity and leads the industry in achieving more accurate torque management.] <Contact for inquiries about the automatic hydraulic pump> Please contact us for free demos, quotes, and information requests.

■ The hydraulic nut can tighten 40 flange bolts simultaneously at once! ■ The hydraulic nut is a revolutionary nut that tightens bolts by pulling them with the hydraulic function of the nut body! The nut itself tightens the bolt. ■ Since the nut is tightened by pulling force without twisting, there is no frictional influence with the seating surface, allowing for "direct axial force on the bolt," which enables precise tightening of the bolt. ■ It tightens multiple bolts simultaneously and uniformly, preventing variation. ■ Because it pulls and tightens the bolt hydraulically, it does not damage the surface of the flange or the seating surface of the nut. ■ Tightening through axial force management achieves higher precision than torque management due to the absence of frictional influence. ■ It accommodates large bolt tightening from M20 to M300 class. ■ There is also a stainless steel version of the hydraulic nut with anti-rust specifications. <For inquiries about purchasing hydraulic nuts> Please contact us for free demos, quotes, and material requests.

The tightening axial force is uniform, preventing uneven tightening of flanges. (Proven capability of tightening 40 flange bolts simultaneously in parallel.) - The bolts are pulled hydraulically, applying tensile load for tightening, which eliminates the influence of friction between the thread surface and the seating surface. "Axial force can be managed directly," allowing for more accurate axial force management compared to torque management. - A standard model of bolt tensioner that has been compacted and lightweight to the extreme. It can be used for bolt tightening even in narrow spaces. Custom manufacturing is also available. - It is a puller exchange type, allowing one main unit to accommodate multiple bolt sizes, providing high versatility. - Since the bolts are not twisted, friction heat does not occur, preventing galling between the nut and flange surface and seizing of the threaded parts. <Contact for purchasing or renting bolt tensioners> Please contact us for free demos, quotes, and material requests.
