Tired of troubles caused by separate screws and washers?

Missing washers, screw slippage, loosening and falling off often happen on production lines. Purchasing requires separate orders with complicated reconciliation. Warehouses are overloaded with materials, difficult to count, and wrong/missing deliveries occur frequently. Small parts issues delay delivery and increase after-sales cost—these are the most common pain points for manufacturing and procurement.

Separate screw + washer seems cheap but actually has extremely high hidden costs:

• More assembly steps, double labor time, low efficiency
• Easy to lose or miss washers, leading to loosening and high rework rate
• Multi-SKU management, high inventory pressure, capital & space occupation
• Mismatched specifications, insufficient locking force, no safety & quality guarantee
