40-Hole Hex Cap Screw Assortment Refill, Grade 8, 2625 Pieces, Bin Not Included

2,625 Piece Grade 8 Hex Head Cap Screw, Nut, and Washer Assortment Refill

SKU ASST40C8REFILL

The same 2,625-piece Grade 8 coarse-thread assortment as the Starter Kit — without the bin. If you already own a 40-hole bin, this refill restocks 1/4"-20 through 1/2"-13 UNC bolts, nuts, and washers without paying for storage you already have.

What's Included
  • Grade 8 hex head cap screws — 1/4"-20, 5/16"-18, 3/8"-16, 7/16"-14, and 1/2"-13, multiple lengths per size
  • Grade 8 hex nuts — matching every bolt size in the kit
  • USS flat washers and high-alloy lock washers — one set per diameter
  • 2,625 pieces total
  • Storage is not included — designed for customers who already own a 40-hole bin
Specifications
Thread standard UNC — Unified National Coarse
Grade SAE J429 Grade 8
Tensile strength 150,000 PSI minimum
Finish Yellow zinc
Diameters 1/4"-20, 5/16"-18, 3/8"-16, 7/16"-14, 1/2"-13
Total pieces 2,625
Storage included No — for customers who already own a 40-hole bin
Compatible storage 40-hole metal bin (included with Grade 8 UNC Starter Kit)
Best For
  • Existing bin owners — if you already have a 40-hole metal bin, this refill restocks it completely without the added cost of new storage
  • Heavy industry and construction — coarse threads are faster to install and more resistant to cross-threading, making Grade 8 UNC the go-to for structural, equipment, and field work
  • Fleet and maintenance facilities — shops that cycle through 1/4" through 1/2" coarse-thread Grade 8 fasteners regularly and need a reliable, complete restock
  • Multi-station operations — teams that already have bins set up across the shop and simply need to replenish fasteners, not storage

Don't have a bin yet? The Grade 8 UNC Starter Kit includes both the fasteners and the 40-hole metal bin — everything you need to get organized from scratch.
