- What is the difference between A2(304) and A4(316)?
- A4 316 contains molybdenum, much better anti-chloride performance. Choose A4 for coastal, marine, swimming pool projects.
- Why stainless steel screws get seized during tightening?
- Stainless steel is prone to thread galling. Reduce tightening speed; anti-seize lubricant is suggested for heavy-duty assembly.
- Are stainless steel fasteners completely rust-proof?
- SS304 may stain under heavy salt fog. SS316 performs well in coastal areas, but long-term full seawater immersion still needs regular maintenance.
- What material are your stainless steel fasteners? Will they rust?
- Our standard stock fasteners are made of 304/316 stainless steel. 304 suits dry indoor environments; 316 offers superior salt spray & seawater resistance for coastal and outdoor applications. Stainless steel is not rust-proof completely. Rust may occur under long-term exposure to strong acid or high chloride sealed environment. Please select grades according to your working condition.

- We provide screw, bolt, washer, nail, pins & rivets, threaded insert, stud, rod and stamped parts for your selection. Custom non-standard specifications are also available.
