Average Customer Review:

Set Screws are often used for holding a pulley, gear, or other parts from turning relative to a shaft.

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. Good for permanent setting of parts, the sharp point of the Cone penetrates deep into the surface to lock in place.

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.

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
