Why Purchasing Managers Struggle with Threaded Caps
In 2025, a survey of 312 U.S. manufacturers revealed three recurring issues:
- High Unit Price: Average cost $1.45 per cap – 18% above market average.
- Inconsistent Quality: 27% of batches failed ISO‑9001 inspection, leading to production delays.
- Long Lead Times: Standard delivery 45‑60 days, causing inventory shortages.
These pain points translate directly into higher operational expenses, missed delivery windows, and ultimately, lost revenue.
