A high-torque compatible embedded bolt for resin that is strong against rotation and withdrawal, and does not damage the resin. It allows for nut tightening when embedded in resin parts.

The "SSOO Bolt" is a resin embedded bolt (insert bolt) with a special octagonal head shape, offering excellent torque resistance and pull-out strength. An insert bolt is a bolt that is embedded in resin and fastened with a nut. By tightening with a nut, it allows for the fastening of resin parts to each other or resin parts to metal. It minimizes deformation and cam-out of the resin when fastened with high torque, enabling nut tightening at high torque levels. It can also be used for back embedding (thermal press fitting), making it suitable for shapes that cannot be integrally molded. Since the bolt can be used in an upright position within the resin, it improves the assembly of parts. The product design has been completely revamped, and sizes from M4 to M8 are now available. 【Features】 ● Special shape that minimizes cam-out and slip even when tightened with high torque ● Strong against pull-out, preventing deformation of resin parts ● Usable for both insert (simultaneous molding) and outsert (thermal press fitting) ● Mass production possible due to unique manufacturing methods ● Trusted Octa Lobular series *For more details, please refer to the materials. Feel free to contact us with any inquiries.

<New Product> Adding more peace of mind! A new insert nut that advances weight reduction. "Doesn't rotate" + "Doesn't loosen" = Protects resin products.

The "SSOO Nut PLUS" adds a cap to the reliable outsert nut, the SSOO Nut! It is a new insert nut from the Octa Lobular(R) series. <Are you having trouble fastening resin parts?> With the SSOO Nut PLUS, you can ensure the high torque resistance and pull-out strength of the "non-rotating" SSOO Nut. It solves the fastening issues of resin parts! 【Features】 ■ High torque resistance performance 1.8 times that of knurled products, preventing slipping and co-rotation even when tightened with high torque. ■ High pull-out strength 1.2 times that of knurled products, also excellent in vibration resistance. ■ Adds a horizontal cap to the SSOO Nut! - Can be used with simultaneous molding, making it suitable for thermosetting resins. - The cap prevents resin from wrapping around, ensuring secure fastening. - The horizontal cap can be used in space-constrained battery parts and resin components. - Prevents loosening by ensuring metal contact. It can be used as either an insert or an outsert, allowing you to choose specifications according to your application. *For more details, please refer to the materials available for download in PDF format or feel free to contact us.

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.

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.

Non-magnetic, high-strength, and highly corrosion-resistant austenitic stainless steel bolts. They are environmentally friendly products that do not require heat treatment.

The "high-strength, high-corrosion-resistant stainless steel bolt" is made from austenitic stainless steel based on SUS304 and exceeds the strength classification A2 standard values of JIS B 1054. Through a proprietary molding process (patent obtained), it has achieved strength without the need for heat treatment. 【Features】 - Uses high-corrosion-resistant austenitic stainless steels SUS304 and SUS316 - Achieves high strength by utilizing material strength and work hardening through forging - The proprietary Bausinger effect suppression processing method eliminates the need for strengthening heat treatment, reducing environmental impact - Maintains high corrosion resistance and shortens lead time due to the absence of heat treatment processes - The screw head shape adopts a hexalobular design that offers high torque transmission - Balances corrosion resistance and strength, with a proven track record for use in automotive components (Note) The Bausinger effect refers to the phenomenon where, after applying plastic deformation in one direction, applying a load in the opposite direction results in plastic deformation occurring at a lower stress than when a load is applied again in the same direction. If you are interested in fastening with stainless steel components, please feel free to contact us.

The three-blade design provides stable anti-loosening effects! Thanks to the high-strength friction ring, it can be reused multiple times! [Manufactured by Osaka Forming Co., Ltd.]

The "E-LOCK Nut" handled by Daiichi Industry features a three-blade design that enhances its anti-loosening function and possesses the strength to withstand repeated use. In the case of conventional two-blade products, one blade gets lodged in the thread valley, effectively resulting in a state of anti-loosening with only "one blade," leading to concerns about stability. However, this product's three-blade design effectively increases thread stability with "two blades." Additionally, durability tests under vibration showed no deformation in the three friction rings of this product, proving its ability to withstand repeated use due to the sustained effect of the springs. (Other manufacturers' nuts with high anti-loosening functions may experience deformation.) **Features** 1) The three-blade design provides a more stable anti-loosening effect compared to conventional products. 2) Prevents early detachment even if the tightening axial force decreases. 3) Strong and capable of withstanding repeated use. ★ This product is from Osaka Forming Co., Ltd.
