What Size Nails for Fence Pickets? A Comprehensive Guide
Choosing the right nail size for your fence pickets is crucial for a sturdy, long-lasting fence. Using nails that are too small will result in a weak, wobbly fence prone to damage, while using nails that are too large can split the wood. This guide will help you determine the appropriate nail size based on various factors.
Factors Affecting Nail Size Selection:
Several factors influence the ideal nail size for your fence pickets:
-
Wood Type: Hardwoods like oak require larger nails than softwoods like pine or cedar. Harder woods are more resistant to splitting, allowing you to use longer nails for better holding power. Softer woods are more prone to splitting, requiring shorter nails or pre-drilling pilot holes.
-
Picket Thickness: Thicker pickets naturally require longer nails to ensure secure fastening. Measure the thickness of your pickets to determine the appropriate nail length.
-
Fence Style: The style of your fence also plays a role. A privacy fence with closely spaced pickets might necessitate slightly shorter nails to avoid splitting the pickets. A more open style fence may allow for longer nails.
-
Nail Type: While common nails are frequently used, consider using galvanized nails for outdoor applications to increase their resistance to rust and corrosion. This is particularly crucial in areas with high humidity or rainfall.
Common Nail Sizes and Applications:
Here's a general guideline for common nail sizes used in fence construction:
- 8d (2.5 inch) nails: Often suitable for thinner pickets (less than 1 inch thick) made from softer woods. Pre-drilling pilot holes is recommended.
- 10d (3-inch) nails: A good all-around choice for many picket fence applications, especially for medium-thickness pickets (1-1.5 inches) made of softer or medium-hard woods.
- 12d (3.25-inch) nails: Suitable for thicker pickets (more than 1.5 inches) and hardwoods. Pre-drilling might still be necessary for softer woods to prevent splitting.
- 16d (3.5-inch) nails: Typically used for very thick pickets or where extra strength is needed. Pre-drilling is highly recommended for all wood types.
What size nails should I use for a wooden fence?
The size of nails you should use for a wooden fence depends on the factors outlined above. There's no single "correct" answer, but the sizes mentioned above cover the majority of scenarios. Always err on the side of caution – slightly smaller nails with pre-drilling are preferable to larger nails that could split the wood.
What type of nails should I use for a fence?
Galvanized nails are generally recommended for exterior fence applications due to their increased resistance to rust and corrosion. Common nails can also be used, but their lifespan will be shorter, especially in damp climates.
How long should fence pickets be?
The length of your fence pickets is determined by the desired height of your fence. Standard picket lengths vary, but common sizes include 4, 5, and 6 feet. The length of the pickets does not directly dictate the nail size.
Are 16 penny nails too big for fence pickets?
16 penny nails (3.5 inches) are likely too large for most standard picket fences unless you're working with exceptionally thick hardwoods or require significantly increased holding power. Using such large nails without pre-drilling will almost certainly result in split pickets.
Best Practices for Nail Usage:
-
Pre-drilling: Always pre-drill pilot holes for harder woods or when using longer nails, regardless of wood type. This helps prevent splitting.
-
Proper Nail Placement: Drive nails straight into the wood to maximize holding power. Avoid bending nails.
-
Consistent Nail Spacing: Maintain consistent spacing between nails for a uniform and structurally sound fence.
-
Safety First: Always wear safety glasses when using nails and a hammer.
By carefully considering these factors and following best practices, you can ensure your fence pickets are securely fastened and your fence will stand the test of time. Remember to always check your local building codes for any specific requirements.
