For hard-working shafts, collars, and adjustments, the 1-14 x 1/2 Cup Point Square Head Set Screw provides a cup point with a four-flat wrench head. This pattern remains valuable on equipment where operators repeatedly loosen, reset, and tighten the same fastener.

Mixer and auger shafts may specify square heads so crews can reset collars, hubs, or followers without a special key. Because a square head protrudes and rotates with the shaft, exposed rotating assemblies near personnel may call for a guarded headless set screw instead.

Cold Headers can help confirm pricing and availability for exact-size square-head cup point set screws without making unsupported availability promises. Review the thread, length, square-head dimensions, and cup point diameter before substituting another set screw style.
