Fastener Kits — What You Get & Why They’re Useful
Fastener kits bundle the most-used screws, nuts, washers, and related small parts into a portable organizer so you always have the right size on hand for quick repairs and installs. Assortments typically cover the common diameters, head styles, and finishes used in home, automotive, marine, and jobsite work.
What’s Typically Inside a Fastener Assortment
- A mix of sizes for one family of fasteners (e.g., machine screws, sheet-metal screws, rivets)
- Matching nuts, flat washers, and lock washers where applicable
- Clear, removable bins or labeled compartments for easy restocking
- Optional drivers or small tools in specialty kits (e.g., license plate, hurricane panel, electrical)
Materials & Finishes
- Stainless (18-8 / 304): Everyday corrosion resistance for indoor/outdoor use
- 316 Stainless: Marine/coastal and chemical exposure
- Zinc-Plated Steel: Budget-friendly corrosion protection for general indoor use
- Black Oxide / Alloy: Clean look; light oxidation resistance—best indoors
Inch & Metric (inch/metric)
Some kits are inch-only, some metric-only, and a few include both. Match the thread system to your equipment—mixing inch/metric can damage threads.
Picking the Right Kit by Use Case
- Automotive / Garage: Machine-screw or hex-bolt assortments with nuts, washers, and lock washers
- Marine / Outdoor: 316 stainless kits for long-term corrosion resistance
- Electrical & Low-Voltage: Small machine screws, nuts, and finish washers
- License Plate Hardware: Stainless screws, finish washers, and lock nuts sized for frames (common 6 mm or 1/4")
- Hurricane Prep: Stainless hanger-bolt/wing-nut combos and hurricane screw assortments for temporary panels and shutters (often 1/4-20)
Organizer Details that Matter
- Rigid case with secure latch to survive tool bags and truck boxes
- Removable dividers to reconfigure compartments as you restock
- Clear lid so sizes are visible at a glance
- Label space for part numbers and reorder notes
Restocking & Compatibility
Refill bins with matching bulk fasteners. Note material, diameter, thread, and length on each label to keep future reorders fast and error-free.
Care & Storage Tips
- Keep kits dry; add a small desiccant pack for steel/zinc parts
- Don’t mix stainless and carbon steel in one bin if moisture is possible
- Return unused fasteners to the correct compartment to keep counts accurate
Fastener Kit FAQ
What’s the difference between stainless 18-8 and 316 in kits?
18-8 (304) handles everyday moisture; 316 adds molybdenum for superior marine/coastal corrosion resistance. Choose 316 for salt, chemicals, or year-round outdoor exposure.
Will a kit include both inch and metric pieces?
Some kits are inch-only, some metric-only. Mixing systems can strip or cross-thread, so match the kit to your project. If your gear calls for 6 mm fasteners, don’t substitute 1/4-20, and vice-versa.
Are the compartments labeled and refillable?
Yes—most organizers have labeled or label-ready bins. You can refill bins with the exact sizes/materials from our bulk fasteners to keep the kit complete.
Which kit is best for vehicles or equipment?
Use a machine-screw/hex-bolt assortment with matching nuts and washers. If the application sees weather or road salt, pick stainless—316 for harsh environments.
Do you offer kits for hurricane or storm panels?
Yes—look for assortments with 1/4-20 stainless hanger bolts, wing nuts, washers, and related hardware commonly used to mount temporary plywood or shutter panels.
Are black-oxide kits rust-proof?
Black oxide is mainly cosmetic with light oxidation resistance. Use indoors and avoid moisture; for outdoor use, choose stainless or hot-dip galvanized parts.
How do I choose screw length inside a kit?
Pick a length that passes through the material and fully engages the nut or base threads without bottoming out. When in doubt, test with the next size up and add a washer.
Can I buy organizers without fasteners or add extra cases?
Yes—empty boxes and divider cards are available so you can build custom assortments or expand your setup.
