Lock Washers 7/16 25pk

Lock Washers 7/16 25pk from ALLSTAR PERFORMANCE are essential fastening components that every serious mechanic and engine builder should stock. These split-ring style washers are designed to prevent bolt and screw loosening caused by vibration, making them critical for high-performance automotive applications where engine bay harshness and road feedback can work to back out fasteners. This 25-pack provides the reliable locking action needed to keep critical connections tight over thousands of miles.

The 7/16-inch size fits standard fasteners common in engine bay work, cylinder head hardware, and suspension assembly. Lock washers function by exerting spring tension against the fastener and its mating surface, creating friction that resists rotation even under extreme vibration loads. ALLSTAR PERFORMANCE's design ensures consistent hardness and gap tension across all 25 pieces, meaning you get uniform locking performance on every bolt—no weak spots that could compromise your build.

Professional shops and weekend warriors alike benefit from keeping assorted lock washers on hand for any reassembly scenario. Use these 7/16 lock washers whenever you install fasteners in critical applications, ensuring secure connections that withstand the rigors of automotive performance. Their compact packaging makes storage simple and convenient.
