Why Choose DONGSHAO Heavy Type Lock Washers?

• Enhanced Fastening Force: Featuring superior thickness and material density compared to standard washers, providing exceptional holding power under extreme loads.

• Superior Damping Effect: Specifically engineered to buffer, absorb, and mitigate heavy structural shocks and continuous vibrations in machine equipment.

• Proportional Anti-Loosening: The anti-loosening capacity increases dynamically as the pre-tightening force of the threaded connection pair scales up.

• Certified Factory Direct: Shipped straight from our 10,000 m² state-of-the-art production and heat treatment facilities with competitive wholesale discounts and reliable after-sale services.

Detailed Product Description

Our Single Coil Spring Lock Washers Heavy Type are engineered explicitly for high-load mechanical equipment where structural integrity and safety are critical. These washers serve as an active safety component by providing continuous elastic tension against joint contraction, significantly reducing operational noise and preventing fastener backing-out caused by aggressive mechanical movement.

In practical applications, these heavy-duty helical spring washers are paired with high-strength nuts, screws, and bolts. Widely utilized in steel structures, wind power equipment, heavy automotive assembly, and photovoltaic installations, they offer exceptional stability and reliability. Supported by our dedicated in-house metal surface treatment division and heat treatment plant, they maintain optimal elasticity and corrosion resistance throughout their long service lifespan.

FAQ - Frequently Asked Questions

Q1: What makes the "Heavy Type" spring lock washer different from standard ones?

A: Heavy Type single coil spring lock washers are manufactured with increased material thickness (h) and section width (b). This structural optimization provides a significantly higher fastening force and superior vibration damping, making them ideal for heavy machinery applications where standard washers might fail.

Q2: How does the anti-loosening capability perform during machine operation?

A: The unique helical spring design allows the anti-loosening force to scale up proportionally with the tightening torque applied to the matching bolts. It provides a continuous spring tension that maintains joint friction even under severe physical shocks and continuous vibration.

Q3: Do you support customized sizes or customized metal surface treatments?

A: Yes. Backed by our specialized technical engineering teams, DONGSHAO offers full customization for non-standard specifications. Furthermore, with our own dedicated metal surface treatment division and heat treatment plant, we provide various surface coatings optimized for different harsh industrial environments.

Q4: What is your standard inquiry response time and after-sale service?

A: We respect your project schedules and purchasing timelines. Every inquiry received via our official portal is reviewed by our engineering experts and replied to within 24 hours. We guarantee timely delivery, factory discount pricing, and comprehensive technical after-sale support for all wholesale orders.
