Description
The lock washer is a high-performance fastening component engineered to prevent loosening and maintain preload in bolted assemblies subjected to vibration, shock, or dynamic loads. Designed to pair with standard bolts, nuts, or studs, this washer provides critical locking functionality in mechanical, structural, and industrial applications.
Specifications:
-
Inner Diameter: Sized to fit corresponding fasteners
-
Outer Diameter: Varies slightly by washer type
-
Thickness: Nominal, varies by specification
-
Material: Typically carbon steel; also available in stainless steel or alloy steel
-
Finish Options: Plain, zinc-plated, black oxide, hot-dip galvanized, or other corrosion-resistant coatings
-
Type: Split lock washer (most common), with high-collar and heavy-duty variants available
Features:
-
Helical split design applies continuous spring tension against the fastener and mating surface, reducing loosening under vibration or dynamic loads
-
Compatible with both coarse and fine thread fasteners
-
Heat-treated or hardened options available for improved load resistance
-
Corrosion-resistant finishes extend service life in harsh or outdoor environments
-
Compact and lightweight design effectively maintains clamping force and resists rotation
Applications:
Engineered for assemblies where vibration or movement may compromise fastener integrity, including:
-
Industrial and agricultural machinery
-
Automotive and heavy-duty vehicle assemblies
-
Structural steel connections
-
Rail, marine, and aerospace equipment
-
Power transmission and construction hardware
