Standard 304 stainless steel hex bolts, polished. A2-50 has lower strength, primarily used for interior decoration, high-end furniture, and construction, offering lasting metallic luster and rust resistance.

A2-70 (304) is suitable for general machinery and construction; A4-70 (316) adds molybdenum, enhancing chemical corrosion resistance. Both provide a tensile strength of 700 MPa, making them standard for automated production lines and general manufacturing.

Based on SS 316 material, it achieves the A4-80 high-strength standard through cold working hardening. with resistance to chloride ion pitting corrosion and higher load-bearing capacity, it is an ideal choice for yacht equipment, dock engineering, and underwater fastening.

904L is a super austenitic stainless steel that offers excellent corrosion resistance to strongly reducing media such as dilute sulfuric acid. It is used in fertilizer production, flue gas desulfurization, and the pharmaceutical industry. For extreme environments like deep sea, high pressure, and strong acids, duplex stainless steels UNS S32750 and S32760 are recommended.

A globally adopted metric standard with full thread design. The thread extends directly under the hex head, offering maximum effective fastening travel and adjustment space.

Features a precision smooth shank. Compared to full thread, its shank provides higher shear strength and more precise positioning.

Integrated flange design, effectively replacing flat washers and optimizing clamping force distribution. Available in flat and serrated options.

This material exhibits excellent creep resistance and corrosion resistance. It is used in high-temperature and high-pressure applications, energy engineering, and pressure vessel fields.
