Introducing nuts used for welding to plates and methods for welding studs to plates!
For joining sheet metal parts, tapping is often used, but when using screws, a countersink may be made on the mounting side of the part to ensure that the screw head does not protrude from the surface. In addition to tapping, there are methods such as welding nuts and bolts, as well as press-fitting nuts and bolts. This document introduces these joining methods. Please feel free to download and take a look. [Contents] ■ Countersinking ■ Weld nuts ■ Stud welding ■ Fasteners (press-fit bolts and press-fit nuts) *For more details, please refer to the PDF document or feel free to contact us.
Recommended for soft materials! An insert with self-tapping functionality that offers excellent 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. Furthermore, compared to press-fit types, the external thread section tightly grips the base material without gaps, making it less likely to come loose. 【Features】 ■ Can skip the pre-tapping process ■ Provides high 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.

A case where the change of the manufacturing 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 occurrence) - 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.

By filling the gap between the male and female threads over 360 degrees, the prevention of loosening is ensured against any vibrations.
Are you troubled by "nut loosening" caused by 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 multiple pressed screws on the nut, high-precision bolt axial force is achieved, and the patented sloped washer prevents loosening. Unlike 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 remarkably, and conversely, it can be easily loosened when desired. 【Common Issues】 ■ Frequent use of vibrating equipment 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 difficult 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.

Recommended for domestically produced stainless bolts! Stainless hex nuts with excellent cost performance.
Stainless steel can generate friction heat during tightening, causing the screw part to expand and potentially leading to the phenomenon of "seizing/binding." To address this issue, our product applies a fluoropolymer resin thoroughly to control the friction coefficient during tightening, thereby preventing the occurrence of seizing in bolt-nut engagements under normal conditions. Compared to domestic products, it offers excellent cost performance and does not reach the level of seizing even under conditions of repeated use up to five times. 【Features】 ■ All units selected from domestic manufacturers ■ Manufacturer's product warranty included (with engraving) ■ Superior cost performance compared to domestic products ■ Does not reach the level of seizing even under conditions of repeated use up to five times *For more details, please refer to the PDF document or feel free to contact us.
