Key Features Thread Size: 1"-8 UNC (Coarse Thread) Point Type: Knurled Cup Point for superior vibration resistance Material: Alloy steel for enhanced strength and reliability Finish: Thermal black oxide for mild corrosion protection and a smooth, dark appearance Drive Style: Internal Hex Socket (Allen wrench/hex key required) Application: Securing collars, gears, pulleys, and shafts in rotating or high-torque assemblies Bulk Availability: Cost-efficient packs designed for heavy-duty projects Why Knurled Cup Point Set Screws? The knurled cup point design features serrated edges that dig into mating surfaces, significantly reducing loosening due to vibration or torque. This makes them particularly effective in industrial applications where maintaining a secure hold is critical, even under harsh operating conditions. Ideal Applications Heavy Equipment & Machinery Automotive & Truck Repair Construction & Industrial Assemblies Power Transmission Components (Collars, Gears, Pulleys) Rotating & High-Torque Applications Installation Tips Use a hex socket/Allen wrench correctly sized for the internal drive. Apply consistent, even torque to secure without over-tightening. Ensure the contact surface is clean and free of debris for optimal grip. Periodically check for proper tightness in high-vibration environments.
