Fastening part V-nut

Fastening part V-nut

Standard product of lock nuts.

The V-nut consists of two components: the nut itself and a special spring. A groove is machined into the top surface of the nut to fit the special spring (friction ring), and the protruding part is rolled inward toward the center to secure the friction ring to the top of the nut. Each individual nut and ring, through this mechanism, functions as an excellent locking nut while also creating a stable torque V-cut.

SSOI Nut "High Torque Insert Nut"

SSOI Nut "High Torque Insert Nut"

This is a strong insert nut that prevents slippage (co-rotation and idling) caused by bolt tightening and protects resin products from damage.

Insert nuts for resin (plastic) have traditionally utilized knurled, square, and hexagonal shapes, which have raised concerns about the nuts deforming the resin and spinning freely (slipping or idling) when bolts are tightened with high torque. As a result, we received strong requests from customers to develop insert nuts with shapes that can withstand high torque (high torque strength). We conducted research, development, and prototyping in-house and devised an original shape of insert nut that can handle high torque. It is designed for use during resin molding and also boasts excellent tensile strength (pull-out strength). 【Features】 - Strong nuts that prevent spinning (slipping or idling) and protect resin products from damage. - A unique octagonal shape that enables "high torque tightening," which has not been available before. - We have realized a shape that is difficult to spin, as requested by many customers. For more details, please contact us or download the catalog.

Support for weight reduction. "Basic Knowledge of Insert Nuts that Support Resin Products"

Support for weight reduction. "Basic Knowledge of Insert Nuts that Support Resin Products"

The trend towards lightweight materials is leading to the use of resins. We will clearly explain the basics of "insert nuts" needed for fastening resins, accompanied by illustrations!

An insert nut is a "fastening component" that is embedded in soft materials such as resin (plastic) to enhance the fastening strength of joints. With the aim of reducing weight, the use of resin is increasing. Insert nuts are used for fastening resin parts in various devices such as mobile phones, automobiles, and airplanes. This document provides a clear explanation of the "basic knowledge of insert nuts," including their features, types, usage, and materials, accompanied by illustrations. It also includes information on the types and characteristics of resins used with insert nuts. *For more details, please download the document or contact us directly.*
