Buying advice

When choosing a nut and bolt assortment, consider the hardware grades: Grade 2 for general use, Grade 5 for automotive, and Grade 8 for high-strength applications. For corrosion resistance, stainless steel or zinc-plated is recommended. Look for a set that includes both SAE and metric if you work on diverse projects. Also, check the quality of the storage case - a sturdy box keeps everything organized and prevents loss. Avoid sets with too many rarely-used sizes; instead, focus on a range that matches your typical jobs.
