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

Self-tapping screws that can be screwed in with low torque! The screwing torque is low, reducing fatigue during continuous screwing operations!

Sanrock is an ideal tapping screw that forms strong female 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 female threads are formed through plastic processing, it produces little cutting chips 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 spring washers made of stainless steel, excellent in corrosion resistance!

"TWO LOCK M's" is a screw that incorporates a TWO LOCK washer. Compared to conventional spring washers, it has a wave-shaped design, which provides a greater spring reaction force and makes it more resistant to loosening. Additionally, its unique shape minimizes the biting into the counterpart material during tightening, making it less likely to cause damage. The washer's low height also means that less tightening force is required. As a result, the screw can be shorter and lighter. We have developed and commercialized this steel TWO LOCK with its advantages intact, using stainless materials that are resistant to rust. ● 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 mounting these resin components, JIS standard tapping screws have the following issues: - High screwing torque. - Prone to spinning during tightening completion. - Unable to achieve high pull-out strength. - The area around the screw hole is prone to whitening phenomena. To address these problems, we developed the "P-Lock" 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 adopted various types of stainless steel to combat salt damage, as well as in environments with chlorine, such as hot water pools and septic tanks. 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 offers 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 significantly enhances corrosion resistance. In addition to its resistance to chloride corrosion, it also excels in acid resistance. MS-270 makes maintenance-free operation possible. ● For other functions and details, please refer to the catalog.

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 steels, widely applicable for general uses. SF-160+α offers economic benefits by being free of nickel and molybdenum, along with ferromagnetic properties, low thermal expansion, oxidation resistance, and advanced refining techniques that reduce harmful impurities and inclusions. By adding trace amounts of Cu and Nb, which are effective in enhancing corrosion resistance, it achieves corrosion resistance similar to austenitic stainless steel (SUS304 series). SF-160+α not only contributes to the VA activities of customers using austenitic stainless steel but also facilitates the transition from ordinary steel plated 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 limited applications as fastening components and necessitating an increase in the number of parts used. 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 achieve satisfactory costs. Therefore, through unique manufacturing technology for β type titanium alloy (Ti 15-3-3-3) that has strength equivalent to α+β type, we have successfully achieved continuous forging mass production and realized cost reduction.

Pure titanium screw

High corrosion resistance, lightweight, and excellent biocompatibility screws.

Titanium is classified into three types in terms of materials science: α titanium, α+β titanium, and β titanium. Pure titanium has an α phase, and there are alloys that possess α phase, α+β phase, and β phase. Maruemu Manufacturing has successfully commercialized β-type titanium (Ti15-3-3-3) screws that have strength equivalent to the more expensive α+β titanium (Ti6Al-4V), achieving cost reduction.

High strength and high corrosion-resistant drill screw "PS-550"

A dream new material that surpasses the common sense of stainless steel! High-strength and highly corrosion-resistant stainless steel!

Stainless steel has traditionally been considered to have "good corrosion resistance but insufficient strength." The only exception was the use of martensitic types, which could achieve strength, but their corrosion resistance was still at a level that could hardly be deemed sufficient. The Perfect Stainless Steel, developed through new steelmaking technology, is a completely new type of stainless steel that simultaneously solves these problems, offering high strength and high corrosion resistance. ● For other functions and details, please refer to the catalog.
