⚠️ The Real Cost of Cheap Fasteners & Loose Joints
Vibration loosening
Over 43% of mechanical failures in transport & agri-machinery stem from washer creep. Standard flat washers can’t hold tension.
Hidden cost overruns
Buyers pay 30–50% premiums for “branded” washers that are identical to our serrated spring washer — same ISO, lower price.
Delivery delays
Lead times of 8–12 weeks from European suppliers. Our single coil washer production line ships in 15–25 days.
Inconsistent quality
No two batches match. Our slotted spring washers are tested for hardness, spring-back & dimensional accuracy — every lot.
📊 Data point: A recent study found that 63% of maintenance engineers report recurring loosening issues with standard washers in high-vibration environments. Nylon/steel hybrid serrated washers reduce re-torque events by 71%.
✅ Why Boen’s Nylon Serrated Single Slotted Spiral Tension SS
Engineered for spring tension washers that lock, grip and stay put — even under extreme vibration, thermal cycling or corrosive conditions.
Dual-Lock Serration + Nylon Patch
Our serrated flat washer face bites into mating surfaces, while the nylon element adds friction damping. Slotted spiral design absorbs axial shock.
Precision Single Coil Geometry
Each single coil washer is wound to exact DIN 127/128 & ASME B18.21.1 tolerances. Consistent spring rate = predictable clamping force.
100% Traceable Quality
ISO 9001:2015, RoHS, REACH. Hardness tested per HRC 38–46. Spiral lock washer fatigue tested to 1M cycles.
Export-Ready Logistics
FOB/CIF/DDP — we ship ss spring washer orders to 30+ countries. Average transit: 18 days to Rotterdam, 22 days to LA.

❓ Frequently Asked Questions
1. What is the difference between a nylon spring washer and a standard flat washer?
A nylon spring washer combines a spring steel core with a nylon patch or overlay. The nylon provides friction damping, while the spring action maintains clamping force. A standard flat washer only distributes load — it does not resist loosening. Our serrated spring washer adds bite for extreme vibration resistance.
2. Are Boen’s slotted spring washers compliant with DIN/ASME standards?
Yes. All slotted spring washers are manufactured to DIN 127, DIN 128, and ASME B18.21.1. We also offer single coil washer variants per customer drawings. Every batch is dimensionally inspected and hardness tested (HRC 38–46).
3. What materials are available for spiral lock washers?
We supply spiral lock washer in 301 stainless steel, 304, 316, and 316L, combined with Nylon 66 or Nylon 12. For special environments, we can coat with zinc-nickel or PTFE. Custom material requests are welcome.
4. What is the typical lead time for ss spring washer orders?
Standard ss spring washer orders (up to 50,000 pcs) ship in 15–25 working days. Custom sizes or hybrid materials may require 20–30 days. We offer express production for urgent orders (7–10 days) at a small premium.
5. Do you offer free samples for evaluation?
Yes. We provide free samples (up to 10 pcs per type) for qualified buyers. You only pay shipping. Request via the form below or email shuan@fastenboen.com.
6. How do you ensure quality across large volumes?
We follow a 3-stage QC process: incoming raw material testing, in-process dimensional checks, and final AQL 2.5 sampling. Each lot of serrated flat washer and spring tension washers comes with a certificate of conformance.
7. What shipping methods do you use for export?
We ship via sea freight (FOB/CIF/DDP), air express (DHL, FedEx, UPS), and rail to Europe. Our logistics team tracks every order. Free warehousing in Handan for consolidation.
