Buying advice

Consider material: stainless steel for corrosion resistance, carbon steel for strength. Choose size to match bolt diameter. Split lock washers are best for vibration-prone applications, but may not be suitable for all scenarios; consider Nord-Lock washers for critical joints. Price per piece decreases with larger packs, but only buy what you need.
