A4L-100 is a high-strength stainless steel bolt. It is available in a lineup from M16 to M27.
Based on years of experience with various types of stainless steel, SUS316L is highly regarded for its corrosion resistance and non-magnetic properties, and it is widely available in the market. We have developed bolts with a tensile strength of 1,000 N/mm² using SUS316L, along with nuts and washers designed to be used in combination with these bolts. In the development process, we focused on three points: 1. simplifying the manufacturing process, 2. preventing galling (deterioration of torque coefficient) due to metal contact between the bolt and nut when tightened with high axial force, and 3. ensuring that the nuts and washers, which must withstand the strength of the bolts, are developed from the same material.

Company information
Since our founding in 1927, we have gained the trust of many through the manufacturing and sales of machine tools, screws, and industrial machinery and equipment. In addition, since being appointed as a specialist committee member for JIS standards for hexagon socket screws, steel taper pins, and oilers by the Industrial Technology Institute in 1955, we have been dedicated to the development of the industrial sector for over 50 years. Currently, we focus on the manufacturing and sales of machine tools, precision cutting tools, and high-quality screws, which have been our core business since our inception, and we have expanded our global product offerings to include OSG cutting tools, Ambraco products from the U.S. company SPS, and JST-branded industrial machinery and equipment, establishing a solid position in the industry. As the 21st century becomes increasingly complex and diverse, we aim to continue our efforts based on our fundamental principle of "sound management" since our founding, striving to be of service to everyone.
