Lock washers are used to resist loosening in bolted joints subjected to vibration, shock, and dynamic loading. G-Fast supplies lock washers per print or specification across all common types and materials including split, internal tooth, external tooth, and wedge-lock systems. From general-purpose assemblies to high-vibration environments, we quote directly from your defined requirements.
A lock washer is a hardened or spring-tempered component designed to resist rotation of a fastener after tightening.
Lock washers do not replace proper torque they help maintain clamp force as the joint settles, vibrates, or cycles under load.
General-purpose spring washer used in automotive, machinery, and construction.
Used where the washer must fit within the head diameter.
Provides stronger resistance to rotation under larger heads.
Used where maximum grip is required.
Used in extreme vibration environments such as rail and heavy equipment.
Locking performance depends on the entire joint not just the washer.
Selection must match fastener grade, hardness, load condition, and vibration profile.
Automotive, industrial machinery, electronics, structural, and high-vibration environments.
Domestic sourcing improves quality control, reduces lead times, and ensures compliance.
Every inquiry begins with your print or defined specification.
Standard and custom lock washers, small batch through production runs.
G-Fast supplies lock washers produced to customer specifications and recognized industry standards.
For applications requiring specific materials, hardness, finishes, or performance requirements, we review supplied drawings or specifications for manufacturability, feasibility, and cost efficiency prior to production.
Where appropriate, we may suggest alternative materials, hardness levels, or locking methods. Any recommended changes are reviewed and approved by the customer’s engineering team and incorporated into updated documentation before manufacturing begins.
Lock washers must be equal to or harder than the fastener bearing surface.
