Description
Vibration and thermal cycling will loosen standard fasteners—especially in high-performance applications where reliability isn’t optional. WOODY’s Big Nuts use nylon-insert locking technology to maintain clamp load under extreme conditions, eliminating the need for constant re-torquing. At 96 pieces per pack, you’ll have proven fasteners on hand for engine builds, suspension work, or complete frame-ups.
