Lock Washers

Split lock washers, or spring lock washers, utilize a spring mechanism to resist vibration and prevent loosening. Featuring a unique split design, one side elevates to apply pressure against mating surfaces, ensuring a secure fit. Ideal for softer materials, their effectiveness may vary with harder substrates.

Designed for optimal performance, our curved split lock washers feature a unique wavy design that enhances their grip and vibration resistance in both right- and left-hand bolted joints. Ideal for treated lumber applications, these washers compress upon tightening to securely lock fasteners in place, preventing loosening due to movement or vibration.

Designed for superior grip, these washers feature teeth on their outer edge to securely bite into surfaces, offering enhanced stability compared to internal tooth variants. Ideal for use with larger bolts or screws, they ensure a firm, vibration-resistant hold.

Designed for optimal performance, these concave washers feature flexible external teeth that effectively absorb vibrations and shocks, ensuring a secure fit. Ideal for use in countersunk holes, they are compatible with flat or oval countersunk-style screws, accommodating head angles of 82 or 100 degrees for a flawless finish.

Internal tooth lock washers are designed to prevent nuts and bolt heads from loosening by absorbing shock and reducing vibration. Ideal for electrical applications, these washers enhance conductivity by scraping the contact surface, ensuring a secure and stable connection.

Designed for superior grip, these lock washers boast both internal and external teeth that securely fasten to the nut or bolt head and the contact surface. Ideal for covering oversized holes and bearing surfaces, they are also essential in electrical bonding for enhanced conductivity and security.

Engineered for superior grip, serrated lock washers feature surface serrations that securely bite into both the fastener head and the contact surface, ensuring unmatched holding power. Their enhanced friction effectively prevents loosening, making them ideal for use with soft materials.

Designed for high-performance applications, our wedge lock washers feature a unique two-piece design that interlocks to form a secure wedge, effectively preventing rotation under extreme vibration and dynamic loads. Superior to serrated lock washers, they deliver a higher clamp load and maintain their locking capability even when lubricated. The innovative design engages teeth with wedges upon tightening, relying on tension for a more reliable bolted joint security than traditional friction-based methods.
