Hobbyists assembling or maintaining models will appreciate the simple dependability of Arrowmax AM-13LN0040 Nylon Lock Nuts M4. The nylon ring helps secure the nut against vibration so components stay tightened during use.
M4 is a common thread size across many RC parts, making these lock nuts a versatile spare. Keep a set in your toolkit for routine builds, upgrades, or roadside repairs.
These nuts are produced to withstand normal hobby conditions and repeat removal. Inspect the insert periodically and replace nuts that show signs of wear or reduced locking action.
