How to Use:
Choose the appropriate stainless steel grade (A2 for most environments, A4 for marine/chemical) and size. Use a clean, properly sized hex wrench or socket to avoid galling (cold welding common with stainless). Apply moderate, steady torque. Using a lubricant specifically designed for stainless steel (e.g., nickel-based anti-seize) on the threads is highly recommended to prevent galling and seizing, especially in critical or repetitive assembly/disassembly applications. Always pair with matching stainless steel nuts and washers to prevent galvanic corrosion. Avoid over-tightening.
