Black Oxide Alloy Steel Socket Cap Screw, Low Head, Hex Socket Drive, 1/2"-13, 1-1/2" Length (Pack of 25) Feature
- Socket Cap Screws are durable and reliable
- Black Oxide coating helps reduce friction and provides mild corrosion resistance
- Low head is perfect for tight areas
- 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.
Low head screws are perfect for tight areas, with heads that are about half the height of standard socket heads. Low head screws are not recommended for high strength applications. Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits.
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.
