Nails vs Screws

Nails vs Screws

Nails vs. Screws: The Blood, Sweat, and Tears of 12,000 Pounds of Force

When Florida contractor Rick Moranis (no relation to the actor) used deck screws instead of nails on a hurricane-proof roof, he learned the $47,000 way: "The wind didn't rip off the shingles—it launched entire trusses like SpaceX rockets." Let's settle this ancient feud with data, not dogma.

The Battlefield Setup

Our Torture Chamber:

  • Test 1: Shear strength (hydraulic press)
  • Test 2: Withdrawal resistance (industrial winch)
  • Test 3: Weathering (saltwater fog chamber)
  • Test 4: Speed challenge (pro carpenters vs. DIYers)
  • Real-World Case: Rebuilt a 1940s barn using alternating fasteners

Spoiler: The barn survived—but 23% of fasteners failed spectacularly.

The Contenders

Nails: The Speedy Bruisers

Types Tested:

  • Common nails (16d)
  • Ring-shank nails
  • Pneumatic framing nails

Superpower:

  • Installs 3x faster than screws (1.2 seconds vs. 3.8 seconds average)
  • Handles shear force like Thor’s hammer

Kryptonite:

  • Withdrawal resistance of a soggy noodle

Shocking Case:
A Chicago deck collapsed because ring-shank nails walked out over winter. The fix? Screws. The cost? $12,400 in maple planks.

Screws: The Precision Engineers

Types Tested:

  • #9 Deck screws
  • Drywall screws
  • Structural SDS screws

Superpower:

  • Withdrawal strength 10x greater than nails
  • Adjustability: The "undo button" of fasteners

Kryptonite:

  • Shear strength of overbaked croissants

Bizarre Fail:
Minnesota shed builder Hank J. sheared 200 screws trying to hang a tire swing. Solution? 16d nails. Lesson? "Screws snap under playground chaos."

The Gloves-Off Tests

Test 1: Shear Showdown

Simulated floor joist stress

Fastener Failure Point (lbs) Cost per Joint
16d Common Nail 1,840 lbs $0.18
#9 Deck Screw 678 lbs $0.43
Structural Screw 1,212 lbs $1.10

Verdict: Nails win for framing. Screws cried uncle at 37% of nail strength.

Test 2: Withdrawal Warfare

Hung 250-lb cabinets for 90 days

Fastener Sag (inches) "Creak Factor"
Ring-Shank Nail 0.9" Scream-inducing
#10 Wood Screw 0.1" Library-quiet
Adhesive + Nail 0.4" Occasional moan

Verdict: Screws rule overhead. Nails? "Like trusting chewing gum to hold diamonds."

Test 3: Corrosion Clash

30-day salt spray torture

Fastener Rust Coverage Strength Loss
Galvanized Nail 12% 18%
Zinc Screw 41% 63%
316 Stainless 0.5% 2%

Plot Twist: Hot-dip galvanized nails beat coated screws. Marine projects? Stainless or bankruptcy.

The Hybrid Hacks

1. The Nebraska Two-Step

Barn builder’s secret: Nail for shear + screw for tension.

  • Framing: 16d nails
  • Roof sheathing: Structural screws

Result: Survived 74 mph winds (and Aunt Edna’s hoarding habit).

2. The California Compromise

Earthquake-proofing trick:

  • Shear walls: Ring-shank nails
  • Ledger boards: ½" lag screws

Code Compliance: Passed 7.1 magnitude simulation.

The Future of Fastening

Smart Fasteners (2025 Edition)

  • Nails: RFID-enabled for load monitoring ($0.12 extra each)
  • Screws: Thermochromic tips that change color when overtorqued
  • Game-Changer: Biodegradable bamboo nails (holds 80% of steel strength)

The Final Countdown: When to Choose

NAILS When:

  • Framing walls (shear rules)
  • Installing hardwood floors (flexibility)
  • Building pallets (speed = $$$)

SCREWS When:

  • Deck building (withdrawal matters)
  • Hanging cabinets (precision)
  • Outdoor furniture (adjustability)

Hybrid Alert: Use nail guns with screw assist for projects like:

  • Fence building (nails for posts, screws for rails)
  • Shed roofs (nails for sheathing, screws for trim)
