The weight is half that of standard nuts, and no washer is needed! A lock nut that is resistant to rust and strong against corrosion!
The "E-Nut" is a nut that is resistant to loosening even without the use of a washer. It absorbs vibrations through the screw itself, and since the material has elasticity, it ensures a secure tightening. 【Features】 ■ It has the functions of a flange nut and a spring washer! ■ It absorbs vibrations through the screw itself, making it resistant to loosening! ■ It is strong because the rolling process does not cut the material's structure! 【Suitable for customers like this!】 ◎ Bolts and nuts tend to loosen easily, and it's a problem... ◎ It's a hassle to insert washers and spring washers... ◎ I want to prevent loosening without using adhesive! *For more details, please contact us or download the PDF.

basic information
【Other Features】 〇 Lightweight Due to plastic processing by pressing from sheet material, the weight is about half that of standard nuts. 〇 Resistant to rust and corrosion! Uses SUS-316L. 〇 Comparison between E-Nuts and standard nuts - The deflection of E-Nuts is closely related to the elongation of the bolt, and it has about five times the deflection compared to standard nuts. - The load distribution of standard nuts under load is not uniform and tends to concentrate near the tightening surface, which increases the risk of bolt breakage. (30% of the total load is concentrated on the first thread.) - E-Nuts distribute the load evenly, preventing local fatigue of the bolt, and the clamped object does not experience fatigue either. - In standard nuts, the tightening force directly acts on the thread's flank, while in E-Nuts, the tightening force acts indirectly on the bolt through the outer hexagonal part and the upper variable part, which serve a shock absorber-like role. Therefore, the effective axial length is increased. - The load-bearing surface of standard nuts is adjacent to the mounting hole of the clamped object. In contrast, the load-bearing surface of E-Nuts is located away from the mounting hole, resulting in a larger load area compared to standard nuts, making them suitable for clamping brittle materials.

Company information
Our company's history dates back to April 1957, and thanks to your support, we are approaching nearly half a century. Over these 50 years, we have embarked on the development of numerous new products and successfully achieved mass production. We take pride in this accomplishment and the reliability that has been recognized as a result. The 1950s was a time based on Japan's post-war economic recovery, and from the 1960s onward, it was an era that supported rapid economic growth, particularly marked by remarkable developments in industrial products. Our main business, screws (fastening components), is indispensable, and the standard screws we handle alone number in the hundreds of thousands, with the addition of special products bringing the variety close to infinite, and even now, their value remains unchanged. Since then, we have entered the era of electronics and digital industries, and the industrial structure has shifted from mass production and mass sales to a time of small lots and diverse varieties. Currently, the demands of the industrial world are for originality, quality standardization, and speed, with the primary challenge being the reduction of production costs. To overcome this difficult challenge, the first step is the skill enhancement of all employees, united as one company.
