A product that integrates a hydraulic tensioner and a nut, which is a bolt fastening tool.
Boltight's hydraulic nut is a product that integrates a hydraulic tensioner, which is a bolt fastening tool, with the nut, allowing for easy and precise fastening of large-sized bolts that cannot be tightened by human strength, achieving the desired axial force accurately. The hydraulic nut significantly reduces the time required for installation, and almost all the force generated by hydraulic tensioning is converted into axial force, unaffected by the coefficient of friction. Since the nut does not rotate during tightening, it can be safely operated in narrow spaces, and there is no torsional stress on the threads. It is also possible to tighten multiple hydraulic nuts simultaneously, ensuring that all nuts are fastened uniformly and with accurate axial force.

Recommended for soft materials! An insert with a self-tapping feature that offers good workability.
"Ensat" is an insert nut with a self-tapping feature. It eliminates the need for the tapping process required before inserting the wire insert. Additionally, compared to press-fit types, the external threaded part grips the base material tightly without gaps, making it less likely to come loose. 【Features】 ■ Eliminates the need for the pre-tapping process ■ Provides pull-out strength due to its one-piece molding ■ Reduces distortion of the base material caused by insert insertion *For more details, please refer to the related links or feel free to contact us.
![[Case Study] Elimination of Defects in Small Nuts and Visual Inspection Work](https://image.www.ipros.com/public/product/image/5c3/2000999162/IPROS34603471698073531500.png?w=280&h=280)
A case where the change of the manufacturer and the mechanization of inspection reduced the defect occurrence rate.
We would like to introduce a case where we proposed "switching manufacturers/automating the bagging process" to a battery manufacturer. There was a frequent issue with the small-diameter brass hex nuts used in battery production, where "the taps were cut at an angle." After our proposal, and following audits of two manufacturers, product defects have not occurred since the process changes were approved. 【Case Overview】 ■ Issue - There was a frequent issue with the small-diameter brass hex nuts used in battery production, where "the taps were cut at an angle." ■ Requirements for Solving the Issue - Select manufacturers that can ensure accurate quality control (to prevent occurrences). - Ensure that defective products can be detected during the bagging and inspection processes (to prevent outflow). *For more details, please refer to the related links or feel free to contact us.

Are you troubled by "nut loosening" due to vibration devices? No special tools are needed; you can achieve axial force management with just one hand torque wrench! *Patent obtained.
"LOAD NUT" is a "loosening prevention mechanism axial force management nut" that allows for axial force management with just one hand torque wrench, and it does not loosen. (Compatible with large bolts from M16 to M100 and above.) By tightening the multiple pressed screws on the nut, you can achieve high-precision bolt axial force, and the patented sloped washer prevents loosening. In contrast to typical axial force management tools like "bolt tensioners," which experience a 10% to 20% reduction in residual axial force after tightening, this product has absolutely no "residual axial force," and there are no limitations on the thickness of the objects being fastened. Once tightened, it does not loosen surprisingly, and conversely, it can be easily loosened when desired. 【Common Issues】 ■ Frequent use of vibrating devices causes nuts to loosen... ■ Large hydraulic wrenches or tensioners are expensive and difficult to introduce... ■ There is no power source at the work site... ■ The working space is narrow, making it impossible to use standard tensioners... These issues can be resolved with "LOAD NUT"! For more details, please refer to the PDF materials or feel free to contact us.
The EAO 82 series offers a wide range of accessories, including various options that enhance waterproof and dustproof protection and facilitate smooth installation.
【Efficiency in Installation Work】 By preparing spare seals, screws, and fixing nuts separately, even if they are damaged or lost during installation, work can proceed without interrupting the assembly. Using metal fixing nuts and dedicated tools makes the installation work on the panel easier. 【High Flexibility in Device Design and Standardization of Design】 By replacing with fixing nuts and using dedicated tools, a design with reduced spacing between switches can be achieved without overly considering the assembly process. This increases space-saving design and design flexibility. Using blind plugs allows unused mounting holes to be sealed without compromising the panel design. It is possible to pre-drill mounting holes for future expansions or standardize the panels of models with different numbers of switches. 【Protection of Equipment and Support for Stable Operation】 By preventing fine dust in the factory from entering the switches, the risk of failure is reduced, maintenance is eased, and stable operation of the equipment is supported.
The elastic effect of the disc spring washer absorbs various vibrations and demonstrates a locking effect due to the spring reaction of the disc spring washer!
The dish spring hex nut is a product that integrates two components: a nut section with internal threads and a dome-shaped washer section that has a spring effect. Since the nut section and the dish spring are structured to rotate, it reduces the factors that cause the plating or paint of the fastened items to peel off. Features: ◆ This product integrates a dish spring washer into a hex nut. ◆ By incorporating the dish spring washer into the hex nut, the assembly process is simplified, and work efficiency is improved. ◆ As a single product, it makes installation easy and prevents installation errors. ◆ Being an all-metal product, it excels in heat and cold resistance. *For more details, please download the PDF.
