Tough As Nails Internal Tooth Lock Washers 600 Pack 1 3/8 Inch Zinc Plated Steel Hardware With Rock Solid Anti Vibration Grip No Slip Design For Electrical Grounding And Soft Substrates
✔️ 600 pack 1 3/8 inch zinc plated spring steel fasteners
This bulk pack of six hundred internal tooth washers serves as a practical anti vibration lock ring for machinery bases, generator housings, and automotive chassis mounts. The twisted inner teeth pierce slightly yielding surfaces like aluminum brackets or composite plastics to stop nuts from working loose. Electricians also rely on them to establish a clean grounding path that keeps signal noise low.
✅ 1.394 to 1.418 inch inside diameter accommodates standard threaded shafts✅ 1.92 to 1.95 inch outside diameter spreads load pressure evenly
✅ 0.062 inch wall thickness delivers rated Rockwell hardness retention
✅ Transparent zinc plating blocks oxidation while staying electrically conductive
💡 What mechanism allows internal tooth lock washers to maintain torque under severe vibration
The biting inner ridges press directly into softer mounting plates to halt rotational slippage.
Precise temper treatment keeps the metal flexible enough to cushion high frequency tremors.
Natural oxide barriers on the zinc layer improve conductivity ratings for sensitive control boards.
Maintaining consistent clamp load with these handy rings pays off in longer equipment lifespan.
