1400 Piece Stainless Steel Hex Head Cap Screw, Nut, and Washer Assortment Starter Kit
1,400 Grade 18-8 stainless steel hex head cap screws, hex nuts, and USS flat washers — 40 holes, 1/4" through 3/8", in a large metal bin with QR-coded labels.
What's Included
- Grade 18-8 stainless steel hex head cap screws — 1/4", 5/16", 3/8" in multiple lengths per diameter
- USS flat washers — heavy-gauge, large OD, for structural and outdoor applications
- Grade 18-8 stainless hex nuts and lock washers — matching each bolt diameter
- Large metal bin — 40 holes, pre-sorted
- QR-coded labels — makes reordering individual fasteners easy
- 1,400 pieces total
Specifications
| Material | Grade 18-8 stainless steel (Type 304) |
| Thread standard | UNC (Unified National Coarse) |
| Diameter range | 1/4" through 3/8" |
| Washers included | USS (heavy-gauge) flat washers |
| Total pieces | 1,400 |
| Storage included | Yes — 40-hole metal bin |
Best For
- Marine fabrication and boat repair shops — Grade 18-8 stainless resists salt air and water corrosion
- Food processing and sanitary environment applications — stainless fasteners are required in food-contact and wash-down environments; this kit covers the bolt sizes most commonly used in equipment assembly and maintenance
- Outdoor and corrosive environment construction — docks, decks, bleachers, signage, and outdoor structures subject to moisture and salt spray require stainless fasteners with the correct washer geometry for the substrate
About Grade 18-8 Stainless Steel
Grade 18-8 stainless steel (also called Type 304) is the most common stainless alloy used in commercial fasteners. The "18-8" designation refers to its composition: approximately 18% chromium and 8% nickel. This alloy provides excellent corrosion resistance in most atmospheric, marine, and mild chemical environments.
Important distinctions for stainless fastener selection:
- 18-8 stainless is non-magnetic — useful in electrical and electronic applications where magnetic interference is a concern
- Stainless steel can gall (seize) during installation if the threads run dry; always apply anti-seize lubricant when threading stainless fasteners together
- For saltwater immersion or chloride-heavy environments, Grade 316 stainless (with molybdenum) offers better resistance than 18-8
