Best For
- Existing bin owners — if you already have a 40-hole metal bin from a previous kit purchase, this refill restocks it completely without the added cost of new storage
- High-volume maintenance shops — operations that cycle through 1/4" through 1/2" coarse-thread Grade 5 fasteners regularly and need a reliable, complete restock in one order
- Fleet and industrial facilities — shops with established bin setups across multiple work areas that need to replenish hardware, not buy additional storage
- Multi-location operations — teams that run the same bin system across multiple shops and need a consistent, labeled restock for each location
Don't have a bin yet? The Grade 5 40-Hole Starter Kit includes both the fasteners and the labeled 40-hole metal bin — everything needed to get organized from scratch.
