So, if you’re planning on using a four-inch round or 4×4-inch square post, your post hole will need to be 12 inches in diameter. For a six-foot-high fence post, we would need a hole that’s 36 inches deep and 12 inches in diameter.
What are the dimensions of a 4×4 wood post?
What are the dimensions of a standard 4×4 or 6×6 wood post? The lumber industry defines standard wood post sizes as 4×4 or 6×6. The outside dimensions of the standard 4×4 measure 3-1/2″ x 3-1/2″, and the outside dimensions of the standard 6×6 measure 5-1/2″ x 5-1/2″.
How do you measure the diameter of a fence post?
Step 1 – Measure the circumference of the post (distance around the post). Step 2 – Take that measurement and divide it by pi (3.14) to determine the post diameter.
What size hole is needed for a 4×4 post?
Therefore, the 4×4 post will likely fit into a hole drilled by a 6″ diameter auger. However, this leaves less than 1/2″ at the widest part for cement or dirt to be packed in to secure the post. For this reason, an 8″-10″ auger would work much better and provide the necessary fill space for cement or tamping.
What is the OD of fence post?
In other words, it helps to keep the terminal post from being pulled over due to the high tension needed to keep the stretched fabric taut. The typical diameters for top rail are 1 3/8” O.D. for residential installations and 1 5/8” O.D. for commercial installations, and most fittings are available for both sizes.
How thick is a treated 4×4?
After drying and planing, it will be 1 1⁄2 by 3 1⁄2 inches. These sizes have been jointly published in the National Institute of Standards & Technology Voluntary Product Standard PS 20-10 with support from the U.S. Department of Commerce for wood with a moisture content of 19% or less.
How thick is a 4×4 piece of wood?
A 4/4 board that has been surfaced on two sides (S2S) will measure about 13/16″ inches thick. Hardwoods are usually sold in random widths, but they can also be sold in standard widths like softwoods.
How do you find the diameter?
Divide the circumference (perimeter) by pi. That gives you the diameter. Half of that is the radius. To get the area, square the radius, and then multiply by pi.
What is a circle diameter?
Diameter of a circle
The diameter is the length of the line through the center that touches two points on the edge of the circle.
How many bags of concrete do I need for a post hole?
1 – 4 bags of concrete per fence post are typically what’s needed. This depends on the type of soil, fence design, height, post size and bag weight. In general the depth of the post’s hole needs to be 1/3 to 1/2 of the above ground height of the post.
How far apart should fence posts be?
8 to 12 feet
Most fence posts can be spaced 8 to 12 feet apart. While this is a general criteria, it doesn’t cover all scenarios. For instance, high tensile fence can have larger spacing, requiring line posts every 15 to 20 feet for field fence styles, and as much as 20-30 feet for high tensile barbed and smooth wire.
What diameter is fence pipe?
1 3/8”(33.4mm) O.D. galvanized pipe coupled with slip on rail sleeves for every standard length generally 21′(6.4m) in length. Terminal Posts: End, corner and gate posts: 3 ½”(88.9mm) O.D.
What is the difference between a line post and a terminal post?
Terminal posts include corner posts and gate posts. They are usually taller and larger than line posts. Line posts are the vertical support structures for the chainwire fence which are usually spaced 10 or less feet apart. Other horizontal logs could rest on these line posts.
How thick are galvanized fence posts?
That’s why we choose and recommend heavy duty, contractor grade, 0.095″ inch thick or greater, galvanized steel posts. The metal post above is rated schedule 20, and measures 0.095″ inches thick.
How much load can a 4×4 post support?
An 8-foot 4×4 can typically carry 1,000lbs horizontally along its length without excessive sag, or 500lbs in a center load. Supported at 16” centers and the load jumps to 4,000lbs. When used as a post, the same 4×4 can support up to 6,000 PSI and even more if properly braced.
How deep does a 4×4 fence post need to be?
Dig post hole so diameter of the hole is 3 times the width of the post (i.e., the hole for a 4” wood post should be about 12 inches wide). The depth of the hole should be 1/3-1/2 the post height above ground (i.e., a 6-foot tall fence would require a hole depth of at least 2 feet).
How big is a 4by 4?
Rather, the retailers say, those are “nominal” designations accepted in government-approved industry standards, which also specify actual minimum dimensions — 1½ inches by 3½ inches for a 2×4, for example, and 3½ inches by 3½ inches for a 4×4.
What is the width of a 4×4?
Nominal vs. Actual Measurements of Dimension Lumber
| Nominal Size | Actual Size |
|---|---|
| 2 x 10 | 1 1/2 x 9 1/4 inches (38 x 235 mm) |
| 2 x 12 | 1 1/2 x 11 1/4 inches (38 x 286 mm) |
| 4 x 4 | 3 1/2 x 3 1/2 inches (89 x 89 mm) |
| 4 x 6 | 3 1/2 x 5 1/2 inches (89 x 140 mm) |
What is a 4×4 wood?
4x4s are typically made from “peeler cores,” which are the byproduct of plywood production. When a log is turned on a lathe to produce plywood veneer, the center that remains, called the peeler core, is used as a 4×4 post.
Why is lumber smaller than size?
Typically, that rough cut is smaller than the nominal dimensions because modern technology makes it possible to use the logs more efficiently. For example, a “2×4” board historically started out as a green, rough board actually 2 by 4 inches (51 mm × 102 mm).
Is diameter a length or width?
The diameter is the same as the length or width of any circle.
