Description
Wedge Locking Washer – Delta Protekt® Coated (HEICO-LOCK® System)
Ensure maximum bolt security in the most demanding conditions with the HEICO-LOCK® Wedge Locking Washer, finished with durable Delta Protekt® coating for enhanced corrosion resistance.
Designed to perform under extreme vibration and dynamic loads, this advanced locking system delivers reliable fastening where conventional washers fail.
How It Works
The HEICO-LOCK® system uses a unique wedge-locking principle. When tightened, the external radial teeth securely grip the mating surface. Under dynamic stress, movement can only occur between the internal wedge surfaces—automatically increasing clamping force and preventing loosening.
Key Benefits:
- Maximum vibration resistance – ideal for dynamic and high-load applications
- Reliable bolt security – certified system for both low and high preload levels
- Delta Protekt® coating – excellent corrosion protection for extended service life
- Easy installation – supplied as pre-assembled washer pairs
- Wide compatibility – suitable for high-tensile bolts (8.8, 10.9, 12.9) and corresponding nuts
- Works with lubricated fasteners – maintains performance even under lubrication
