Questions about this product
- What sizes come in this 200-piece locknut kit?
- The set includes the common metric sizes M2, M2.5, M3, M4, M5, M6, and M8. That spread covers most small and mid-size jobs, so you usually have the right nut on hand without a separate trip.
- Why use nylon insert locknuts instead of plain nuts?
- The nylon collar grips the bolt threads and creates prevailing torque. That keeps the nut from backing off under vibration, which is why people use them for automotive, machinery, and equipment that shakes in use.
- Can I reuse these nuts and how hot can they get?
- The nylon insert keeps its grip over several uses, so they're reusable within reason. They handle roughly -40 to 120 degrees C. Past that the nylon can soften and lose its locking hold, so keep them off high-heat parts.
