What are the most important factors in selecting snaps for outdoor furniture covers?

When selecting snaps for outdoor furniture covers, several critical factors ensure durability and functionality. First, prioritize weather-resistant materials like stainless steel or heavy-duty plastic, which resist rust and corrosion. Second, opt for snaps with a secure fastening mechanism to prevent covers from loosening in strong winds. Third, consider the size and strength of the snaps to match the cover's weight and fabric thickness. Additionally, ease of use is essential—snaps should be simple to open and close while remaining sturdy. Lastly, choose UV-resistant snaps to withstand prolonged sun exposure without degrading. By focusing on these factors, you can enhance the longevity and performance of your outdoor furniture covers.
