With this nut, you'll be satisfied! Solve issues of slipping and spinning! The complete version of the 'High Torque Compatible Outsert Nut (SSOO Nut) Booklet' has been released!

Introducing the SSOO nut, which protects resin parts and enables high-torque tightening. We will showcase examples of weight reduction and cost benefits made possible by the SSOO nut!

The SSOO nut is a heat-pressed insert nut (outsert nut) that achieves "difficulty in rotation" and "high pull-out strength." 【High Torque Compatibility】 Due to its special octagonal shape (Octa Lobular), it is resistant to free spinning and co-spinning, protecting resin components and allowing for high torque tightening. 【Difficult to Pull Out】 By providing unevenness on the shaft, pull-out strength is improved. It also has high vibration resistance, enabling a reduction in the number of components and weight savings. 【Cost】 Using a widely available material (SWCH10R), there is no need to worry about fluctuations in material costs. High-speed production through forging and rolling allows for cost-effective mass production. 【Usage Method】 Since it can be back-filled through heat pressing, it is easy to handle. This document provides detailed information about the features, specifications, and examples of the SSOO nut. If you are considering the use of insert nuts for resin, please take a look.

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.

We are offering free technical materials that demonstrate the strength of SSOI nuts! The materials include a wealth of test data such as tensile tests, torque strength tests, and tightening tests.

The SSOI nut improves torque resistance performance by being molded into a special octagonal shape. It is an insert nut that achieves "difficulty in rotation" and "difficulty in removal," molded simultaneously during resin molding. This technical report presents abundant test data, including tensile tests and torque strength tests, as well as adoption results, explaining the excellent performance of the SSOI nut. ● "Difficulty in rotation" By molding into a special octagonal shape, the torque resistance performance has been significantly improved compared to conventional insert nuts. It prevents the nut from spinning freely (back spinning) during high-torque tightening. 【Verification Test Results】 Torque strength test results (Material: MC Nylon): 25N·m or more ● "Difficulty in removal" Designed for simultaneous use with resin molding, it has excellent tensile (pull-out) strength. It features high vibration resistance and high rotational torque, making it difficult to loosen. 【Verification Test Results】 Pull-out load test results (Material: MC Nylon): 8250N ● Shape As a non-through type, there is no need to worry about resin flowing into the screw hole. 【Adoption Examples】 Resin parts such as air cleaners and intake manifolds. *For detailed technical information, please refer to the download.
