Square Head Set Screw, Cup Point, 1/2-13 x 6 Case Hardened Steel Thermal Black Oxide Full Thread (Quantity: 25) Coarse Thread, 1/2 inch Square Head Bolts, Length: 6 inch
Square Head for Secure Wrench Engagement Allows high torque installation and easy access in tight or recessed applications.
Cup Point for Reliable Holding Power Indents into mating material to resist loosening under vibration or load.
1/2"-13 UNC Thread – Full Thread Length Standard coarse thread provides strong grip and maximum surface engagement.
Thermal Black Oxide Finish. Provides mild corrosion resistance and a clean, low-glare industrial look. Black Oxide is not a protective finish and will rust if exposed to moisture. Stainless Steel material is recommended for environments with moisture
Standard/Spec: ASME B18.6.2. Square Head - High torque application without stripping; easy to grip with wrenches
Case Hardened Steel for Surface Toughness Heat-treated exterior resists wear while maintaining a ductile core.
Industrial Machinery & Equipment Manufacturers - To lock shafts, collars, pulleys, or gears in place on rotating equipment. Often found in heavy-duty mechanical assemblies that need high holding force
Used in steel frameworks, grating panels, and support brackets. Square heads are easier to grip and turn with adjustable wrenches on job sites
Ideal for dirty, oily environments where hex drives slip or round out. Durable under high vibration and harsh environmental conditions
Preferred in older or legacy machinery where square sockets were standard. Easier to install/remove when worn or partially corroded
