The Metric variant contains 292 pieces in M6, M8, and M10 sizes using metric coarse thread. The SAE variant contains 262 pieces in 1/4-20, 5/16-18, and 3/8-16 sizes using UNC (Unified National Coarse) thread. Choose Metric for most international and European equipment; choose SAE for North American machinery and vehicles. Are these bolts suitable for outdoor or marine use? Yes. 304 stainless steel (A2 grade) offers strong resistance to rust and corrosion in wet, humid, and saltwater-adjacent environments. It is widely used in marine hardware, outdoor furniture, and coastal construction. Do the lock washers prevent bolts from loosening under vibration? Yes. The split lock washers included in this kit are designed to bite into both the fastener and the mating surface under torque, resisting loosening caused by vibration and dynamic loads. What tools do I need to install these bolts? A standard hex wrench, open-end wrench, or socket set is all you need. The hex head profile is compatible with any common hand tool or power tool socket. A precision tweezers is included in the kit for handling small pieces in tight spaces. Can I use these bolts in food-processing or food-contact environments? 304 stainless steel is generally considered food-safe and is commonly used in food-processing equipment. However, for regulated food-contact applications, please verify compliance with your local food safety standards before use. Are the bolt lengths consistent across all sizes in the kit? Each size group includes multiple lengths. For example, the Metric kit includes M6 bolts ranging from 12 mm to 30 mm, and M8 bolts from 20 mm to 30 mm. Refer to the What's in the Box section above for the full breakdown by size and quantity. Is the storage case reusable and durable? Yes. The clear plastic compartment case is designed for repeated use. Each compartment is sized to hold its designated fastener type, making it easy to refill individual sizes as needed.
