The 1-8 x 2 1/2 Cup Point Square Head Set Screw is made for applications where a square external head remains easier to grip than an internal drive. Because there is no internal recess, the drive is less likely to pack with debris during plant maintenance or field repair.

Agricultural implements and tillage equipment often keep square-head set screw callouts because field adjustment with common wrenches matters.

Cold Headers is a practical sourcing contact when a print still calls for square-head cup point hardware in a specific size. Review the thread, length, square-head dimensions, and cup point diameter before substituting another set screw style.
