| J-Bolt - One common use of J bolts is as cast-in-place anchor bolts. Used to affix various objects to concrete, J bolts provide a great deal of support and stability, with the shape hooking the bolt in place so that it will not come loose. When J bolts are cast in place, they are inserted into concrete while it sets in a desired location, with the threading sticking out so that things can be bolted down. J bolts can also be inserted through drilled holes in metal and wood, with the loop of the bolt creating a very sturdy hook. |

Term
Name two types of sawed lumber. |
|
Definition
1. "plain-sawed" produces flat-grained boards.
2. "quartersawn" produces edge- or vertical-grained boards. |
|
|
Term
| Describe the characteristics of Plain-sawed lumber. |
|
Definition
1. Made by sawing across the entire log.
2. Less expensive.
3. Less affected by knots.
4. Shrinkage/swelling is seen more in the width than the thickness of the board.
5. Tend to easily develop checks & surface splits during seasoning. |
|
|
Term
| Describe the characteristics of Quartersawn lumber. |
|
Definition
1. Cut from a quarter-section of log.
2. More expensive.
3. Shrinkage/swelling is seen less in the width than the thickness of the board.
4. Edge-grained lumber wears more evenly & is less susceptible to twisting & cupping. |

Term
| What is cross-grained lumber? |
|
Definition
Produced by improper sawing. Occurs when either the fibers or grain of wood aren't parallel to the edge of the member. It's more susceptible to warpage, & shrinkage, rough faces, torn or lifted grain & structural weakness. |
