Hot press-in type insert (outsert) nut "SSOO nut"

Suppresses deformation of resin products. Special shape that is less likely to slip even under high torque. High pull-out strength also reduces the number of screw components and contributes to weight reduction.

The "SSOO Nut" features fine irregularities on the surface of the shaft to enhance torque resistance performance. It is a heat-pressed insert nut that achieves "difficulty in rotation" and "high pull-out strength." Even when tightened with high torque, it does not slip, preventing damage to resin products. Additionally, its excellent pull-out strength contributes to weight reduction by reducing the number of components. Available sizes include M4, M5, M6, and M8. 【Features】 ■ Shape designed to prevent slipping and rotation, protecting resin products from damage ■ Contributes to weight reduction through the reduction of components and downsizing ■ Torque strength and pull-out strength have been verified through testing ■ Proven track record as an automotive component *You can download PDF materials such as verification test data. For more details on specifications and pilot holes, please feel free to contact us.

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.

Bag nut JIS Type 3 "Cap nut"

The bag nut is the original of JIS Type 3! We offer a variety of product series including iron, stainless steel, titanium, and weld (welding) nuts.

The founder of Daiichi Kogyo Co., Ltd., Akira Suzuki, was the first in Japan to manufacture and sell a bag nut (JIS Type 3 cap nut) with a cap that is press-formed onto a nut.

The founder of Daiichi Kogyo Co., Ltd., Akira Suzuki, was the first in Japan to manufacture and sell a bag nut (JIS Type 3 cap nut) with a cap formed by pressing onto a nut.

  • NEW
  • COMPANY

On July 1, 2026 (Wednesday), talent Risa Yoshiki has been appointed as the official ambassador of b-search Co., Ltd. We are pleased to announce the appointment of Risa Yoshiki, who is active in various fields such as television and magazines, as our official ambassador (effective July 1, 2026). With this ambassador appointment, we at b-search Co., Ltd. aim to deliver the best recruitment solutions to many companies struggling with hiring activities, while also strongly promoting the joy of taking on challenges in work and the appeal of new ways of working to job seekers considering career changes or employment. ■ Background of the official ambassador appointment In today's world, where the declining labor force due to low birth rates and an aging population is advancing, "acquiring and retaining talent" has become an extremely important management issue that affects corporate growth. What is required in future recruitment activities is not the traditional method of "simply posting job advertisements and waiting for applications." What is urgently needed now is "proactive recruitment," which involves partnering with companies as their "best No. 2" to consistently promote everything from the planning of recruitment strategies to the establishment of systems that yield results.
