Best For
- Existing bin owners — if you already have a 24-hole drawer from a previous kit purchase, this refill restocks it completely without the added cost of new storage
- Machine shops and fabrication facilities — socket cap screws are a production staple for fixtures, tooling, enclosures, and assemblies that require a flush or recessed drive
- Maintenance and repair operations — high-strength alloy socket head screws for equipment panels, guards, and structural connections that see regular disassembly
- Industrial and fleet shops — operations that cycle through 1/4"–1/2" socket cap screws and need a reliable restocking option without managing individual SKUs
Don't have a drawer yet? The 408-Piece Socket Cap Screw Assortment Starter Kit includes both the fasteners and the labeled 24-hole drawer — everything you need to get set up from scratch.
