Non-circular low-torque stainless steel tapping screw "Sunrock"

Low-torque tapping screws that can be screwed in! With low screwing torque, it reduces fatigue during continuous screw tightening work!

Sanrock is an ideal tapping screw that forms strong internal threads with a small screwing torque. The cross-section of the screw part is shaped like a rice ball, with its apex offset in a spiral manner. These two structural features enable a small screwing torque and smooth screwing performance. Additionally, since the internal threads are formed through plastic processing, it generates little chip waste and allows for smooth fastening. ● For other functions and details, please download the catalog.

Spring washer incorporated screw "TWO LOCK M's"

Ideal for delicate painted products! Screws with integrated stainless steel spring washers that excel in corrosion resistance!

"TWO LOCK M's" is a screw that incorporates a TWO LOCK washer. Compared to conventional spring washers, it has a wavy shape, which provides greater spring resistance and is more resistant to loosening. Additionally, its unique shape minimizes the biting into the counterpart material during tightening, making it less prone to damage. The washer's low height also means that less tightening is required. Therefore, the screw can be shorter and lighter. We have developed and commercialized this steel TWO LOCK with its advantages intact, using rust-resistant stainless steel material. ● For other functions and details, please download the catalog.

Resin-specific tapping screw "P-Lock"

A tapping screw specifically for resin with low insertion torque and minimal chip production!

Currently, resin components are widely used in home appliances and automotive parts. As screws for attaching these resin components, JIS standard tapping screws have the following issues: - High screwing torque. - Prone to spinning when tightening is completed. - Cannot achieve high pull-out strength. - The area around the screw hole is prone to whitening. To address these problems, we have developed the "P-Lock," a tapping screw specifically for resin. ● For other functions and details, please refer to the catalog.

Corrosion-resistant screw for seawater "MS (Marine Stainless) -270"

Achieving excellent corrosion and acid resistance in seawater! Screws that suppress localized corrosion!

Seawater utilization devices, marine structures, and food machinery have all been subjected to salt damage, as well as environments with chlorine, such as hot water pools and septic tanks, where various stainless steels have been employed. However, conventional stainless steels are prone to localized corrosion in solutions containing chloride ions, such as seawater, and in chlorine environments, which limits their use and necessitates frequent maintenance. MS-270 is an austenitic stainless steel that exhibits superior resistance to chloride corrosion and stress corrosion cracking compared to SUS316 and duplex stainless steels. By adding molybdenum, nitrogen, and copper to high chromium and high nickel, MS-270 is a special stainless steel that significantly enhances corrosion resistance. In addition to its resistance to chloride corrosion, it also excels in acid resistance. MS-270 enables the realization of maintenance-free applications. ● For other functions and details, please refer to the catalog.

Light and strong! "Magnesium alloy screws"

Ultra-lightweight! Successfully achieved mass production ahead of the world.

The specific gravity of magnesium is two-thirds that of aluminum and one-fourth that of stainless steel, making it the lightest metal among practical metals used as structural materials. Its alloys excel in specific strength, electromagnetic shielding, and vibration absorption, and are suitable for fastening magnesium alloy housings, as they do not cause galvanic corrosion when in contact with magnesium alloys. This makes them applicable in a wide range of fields, including information technology, home appliances, automobiles, and aviation. A new history of magnesium alloys begins here.

High-performance screw! "Super Ferrite-160 (SF-160)"

High corrosion resistance, low thermal expansion, strong magnetism! High-performance ferrite-based stainless steel!

We have developed a high-performance ferritic stainless steel "SF-160+α" that achieves corrosion resistance and workability comparable to general-purpose austenitic stainless steel, widely suitable for various applications. SF-160+α offers economic advantages by being free of nickel and molybdenum, along with strong magnetic properties, low thermal expansion, oxidation resistance, and advanced refining technology that reduces harmful impurities and inclusions. By adding trace amounts of copper and niobium, it achieves corrosion resistance close to that of austenitic stainless steel (SUS304 series). SF-160+α not only contributes to the value-added activities of customers using austenitic stainless steel but also facilitates the transition from ordinary steel coated products, providing solutions for a wide range of applications. ● For more features and details, please download the catalog.

High-strength titanium alloy screws "β titanium alloy screws"

High-performance titanium alloy screws that combine lightweight and high strength!

Most of the titanium circulating in the general market is pure titanium, which does not meet satisfactory strength requirements, leading to limitations in the adoption of fastening components and the need to increase the number of uses. On the other hand, high-strength α+β type titanium alloys (Ti6Al-4V) have been adopted in some markets, but the α+β type, being difficult to process, is produced through hot forging and machining, making it hard to say that the costs are satisfactory. Therefore, through a unique manufacturing technology for β type titanium alloy (Ti 15-3-3-3) that has strength equivalent to that of α+β type, we have successfully achieved continuous forging mass production and realized cost reduction.
