Cup Point Square Head Set Screw, Case Hardened, Plain (Inch)
Case‑hardened cup point square head set screws deliver rugged, high‑torque fastening ideal for mechanical, agricultural, and industrial equipment. The square‑shaped external head provides excellent tool grip for installation using wrenches or pliers, making these screws especially valuable in applications where fast adjustments, strong clamping force, and reliable surface bite are required.
The cup point design features a concave tip that bites securely into the mating surface, providing high holding strength while minimizing surface damage. This makes cup point square head set screws ideal for securing shafts, pulleys, collars, couplings, and other rotating or vibration‑prone components.
The plain (uncoated) finish allows consistent torque transfer and is suited for indoor or controlled environments where additional corrosion protection is not required.

These case‑hardened square head cup point set screws feature a tough, wear‑resistant outer layer with a ductile core, delivering durability and resistance to rounding, stripping, and deformation under heavy torque. The external square head makes them easy to adjust and remove even in greasy, dirty, or outdoor conditions where socket drives may not be ideal.
The cup point offers a combination of secure seating, strong grip, and reduced surface penetration, making these screws a dependable solution for machinery maintenance, industrial repair, farm equipment, conveyors, and mechanical assemblies requiring robust holding power.
Available in a full range of thread sizes and lengths to support OEM, MRO, and general mechanical applications.
