Description
The 1/2" 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 1/2"-diameter bolts, nuts, or studs, this washer adds critical locking functionality in mechanical, structural, and industrial applications.
Specifications:
-
Inner Diameter: 1/2" (fits 1/2"-diameter fasteners)
-
Outer Diameter: Approximately 7/8" (varies slightly by type)
-
Thickness: Approximately 3/32" (nominal)
-
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), available in high-collar and heavy-duty variants
Features:
-
Helical split design exerts continuous spring tension against the bolt and mating surface, reducing the chance of loosening under dynamic loads
-
Compatible with coarse and fine thread fasteners in the 1/2" nominal size range
-
Heat-treated or hardened options available for enhanced load resistance
-
Corrosion-resistant coatings extend service life in harsh or outdoor environments
-
Compact and lightweight, yet highly effective in resisting rotation and maintaining clamping force
Applications:
Engineered for use in assemblies where vibration or movement may compromise fastener integrity, including:
-
Industrial and agricultural machinery
-
Automotive and heavy truck assemblies
-
Structural steel connections
-
Rail, marine, and aerospace equipment
-
Power transmission and construction hardware
