藤本産業 List of Products and Services

By adopting high-strength bolt steel with excellent "delayed fracture resistance characteristics," we achieve a tensile strength of 1,400 N/mm² while maintaining an elongation of over 9%. Furthermore, the use of aerospace-grade "MJ screws" results in a shallower valley at the screw section and a larger radius at the bottom of the valley compared to standard specifications, which enhances fatigue resistance by alleviating the notch effect.

Bonding fasteners are manufactured by the British specialist company bigHead. Regardless of the requirements, we collaborate with your design engineers to achieve the best possible performance. 【Advantages】 ■ Reduced risk of through-holes in thin sheets: We provide load-distributing anchor points that reduce the risk of through-holes in thin sheets. Due to the large surface area, the adhesive easily bonds to the hole-punched base design, helping to prevent rotation. ■ Reduced production costs: - Operations such as drilling, punching, clamping, and riveting are unnecessary, allowing for easy creation of fixed points. - It features an extremely simple structure with a thin head and fixing part that are welded together. It can be applied to various applications. ■ High versatility: - It can be embedded in composite materials and plastics. - It can be embedded during the molding process or bonded to the surface with adhesive after molding. Each method has its own advantages.

It can be installed seamlessly with a very high load capacity. There are two types available: one with a groove and one with three holes, providing various screw inserts according to the required fixing method. 【Features】 ■ It can be installed mainly in soft metals and alloys (such as aluminum, magnesium, zinc), plastics, and wood. ■ Thin-walled inserts are ideal for limited spaces, and they can also be screwed in by machine. ■ Tapping before insertion is unnecessary; as long as a pilot hole is processed in the base material, it can be directly embedded.

• Safety and consumables

**Features** - Suitable not only for metal and plastic substrates but also for softer materials such as aluminum, magnesium, and titanium. - By using lightweight materials, it contributes to cost reduction in manufacturing while maintaining the strength of the screw threads. - Products are available that accommodate various specifications, including metric coarse and fine, Unified coarse and fine (UNC/UNF), British standards (BSW, BSC, BA, BSP), and American standards (NPT), covering a wide range of sizes from 2mm to 100mm. - There are two methods: free-running and screw-locking, and both can be selected according to the application from tangless types and types with tangs.

Self-clinching fasteners (press-fit fasteners) are a type of fastener that works by plastically deforming the material when pressed into a pre-drilled hole, causing it to become fixed in place. The sawtooth-shaped locking ring serves to prevent rotation. They provide stable, high fastening strength and a beautiful finish, and can also be used on thin plates where threading is considered difficult. 【Advantages】 ■ Low-cost and environmentally friendly joining method ■ Strong load-bearing capacity for thin panels ■ Easy installation ■ Reduction in man-hours ■ Pull-out force and load torque ■ Clean appearance

Fortune Bright, a Taiwanese manufacturer, exports its FB lock nuts not only within Taiwan but also to Japan, South Korea, the United States, and Europe. 【Features】 ■ Excellent safety: Stable locking effect under intense vibrations, high temperatures, and low temperatures ■ Excellent reliability: Outstanding locking effect even with repeated use ■ Excellent economy: No need for re-tightening, enhanced effectiveness, cost-effective

• Safety and consumables

The baked-on nuts have high adhesion, making it difficult for the plating to peel off, allowing for repeated use. Additionally, the smooth tin plating finish reduces the friction coefficient of the screw surface and seating surface, increasing axial force, while the friction coefficient is not too low, thereby reducing the risk of over-torque compared to anti-seize agents. 【Features】 ■ High anti-seizing and galling prevention effect: By applying a three-layer plating, not only is the anti-seizing effect achieved, but also improvements in aesthetics and adhesion strength. ■ Reusable: Unlike coating agents, the high adhesion of the plating makes it difficult to peel off, and even after repeating tightening tests eight times, the anti-seizing effect remains. ■ Clean: With a dry finish, there is no leakage like when using lubricants, preventing dirt. Furthermore, since no application time is required, work time can be reduced. ■ Cost reduction: Time spent on replacing seized nuts can be reduced, leading to a wide range of cost savings, including labor costs, tool strain, and the risk of injuries related to the work.

SUS 304CUN is an austenitic stainless steel (A2) that boasts high strength (A2-90, A2-100), high heat resistance, high corrosion resistance, and non-magnetic properties, making it a strong and rust-resistant high-strength material. By adding copper (CU) and nitrogen (N), it is possible to increase strength while ensuring non-magnetic properties, and it has stress corrosion cracking resistance comparable to SUS 316. Furthermore, SUS 304N2, which is SUS 304 with added nitrogen (N) and niobium (Nb), is a stainless steel that enhances strength while minimizing the reduction in ductility. It is used in structural strength members and high-pressure vessels. High-strength stainless steel washers that can withstand A2-100 specifications using SUS 304N2 have also been developed. These washers prevent plastic deformation (dimpling) around the holes of the mating components that occurs during tightening with high-strength fasteners, providing a locking effect against loosening.
