Push Lock Washers
Push Lock Washers | Self-Locking Star Washers for Secure Fastening
Push lock washers, also known as self-locking washers, push-on lock washers, star-lock washers, press-fit lock washers, or lock washers for sheet metal, are designed to prevent loosening of fasteners due to vibration or dynamic load. Their star-shaped teeth bite into the surface of the material, creating a secure grip without needing additional lock nuts or adhesives.
A push-lock washer works by providing a positive locking action between the fastener and the assembly surface. The radial teeth or serrations around the washer’s edge dig into both the fastener head and substrate, preventing rotation and maintaining preload under vibration. This makes star-washer locks a reliable choice in assemblies where consistent clamping force and joint security are critical.
Key Features & Benefits
- Provides vibration resistance and prevents self-loosening
- Eliminates the need for secondary locking nuts or thread adhesives
- Simple press-fit installation—no special tools required
- Suitable for both threaded and non-threaded fasteners
- Available in carbon steel, stainless steel (304/316), zinc-plated, and phosphate finishes
- Ideal for thin sheet metal, electrical enclosures, and control panels
Applications of Push Lock Washers
Push Lock Washers provide reliable locking in space-constrained applications, where traditional methods may be inefficient.
Ideal for securing fasteners in automotive applications exposed to moderate vibrations, for fast, tool-free locking.
Prevents loosening of fasteners in electrical systems with limited space for additional locking mechanisms, where vibration resistance is vital
Used in plumbing systems to secure components without the need for extra nuts or tools.
Provides secure fastening for furniture without requiring specialized tools or additional hardware, for secure, quick assembly.
Ideal for securing fasteners in appliances and power tools exposed to moderate forces.
