Here are some key advantages of using 32mm coil nails:

• Penetration - The longer length provides deeper penetration into wood members compared to shorter nails. This results in stronger holding power.

• Structural Integrity - The penetration allows 32mm nails to securely fasten multiple layers of materials like sheathing and siding to wall frames with a single fastener.

• Uniform Driving - Collated coils allow for consistent driving depth unlike hand-driven spot nailing which can vary. Uniformity adds to structural strength.

• Application Versatility - The length works for a variety of tasks like attaching siding/roofing, subfloors, decking boards, reinforcing joist hangers, etc.

• Reduced Labor - Fewer fasteners are needed compared to shorter nails, saving time. Fewer nail holes also leave less visible marks.

• Rust Prevention - Longer shanks with full thread engagement are less prone to strip or break compared to shorter nails in exterior shear applications.

• Durability - Sufficient shank length keeps the fastener point safely embedded when the wood shrinks or swells due to weather/stress.

• Code Compliance - 32mm length meets or exceeds standards for sheathing, siding, roofing application as per most building codes.

The performance and versatility make 32mm nails a great all-purpose coil for construction.
