Black Oxide Alloy Steel Set Screw, Hex Socket Drive, Dog Point, 1/4"-20, 1/2" Length (Pack of 10) Reviews
Black Oxide Alloy Steel Set Screw, Hex Socket Drive, Dog Point, 1/4"-20, 1/2" Length (Pack of 10) Feature
- Set Screws keep parts from turning relative to a shaft
- Black Oxide coating helps reduce friction and provides mild corrosion resistance
- Do not have an external head
- Drive system is a hexagon-shaped hole
- Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads
The Black Oxide coating provides some lubricity to the product, meaning that there is less friction generated when using these products. The coating also provides a mild corrosion resistance, but should not be relied on in environments where corrosion resistance is a primary concern.
Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits. Also called extended or pilot point, the flat tip of the Dog Point is extended to fit into a preexisting hole to join two items together.
A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.
