|
|
Brickwork pattern in which the ends of the stretchers, which are bricks laid horizontally with the narrow side of the length exposed, are placed 1Ú2 brick apart in each course to give a latticework effect. This type of wall allows for some privacy and a barrier against wind and sun. |
| Screw
|
|
Fastener which has a flared, slotted head with a raised spiral ridge running down the shank. A screwdriver fits into the screw head to insert or remove the screw. Alternately, Phillips head screws have a crisscross slot in the head rather than the slot. |
| Screw extractor
|
|
Tool which has a left hand steep spiral threaded shank that removes broken off screws when it is inserted into a hole that is drilled down the center of a screw that has a right hand thread. When the extractor is turned, it exerts a loosening force on the screw as it is turned. |
| Screw eye
|
|
Fastener which has a raised spiral ridge running down its shank but, instead of the normal flared slotted head of most screws, it has a circle or loop. When screwed into wood, the eye is exposed and can be used to hold wire or cord or can become part of a two-piece fastener, when matched with a small hook. |
