Enhance fastening reliability with the Set Screws Socket Knurled Cup Point Alloy Thermal Black Oxide 5/16-18 x 5/8. Crafted for tough industrial tasks, this socket set screw features a knurled cup point that delivers secure engagement and consistent load distribution.

Key Features

• Material: Alloy steel for exceptional strength and durability
• Point Type: Knurled cup point provides positive engagement and even load distribution
• Finish: Thermally black oxide offers corrosion resistance with a non-reflective surface
• Drive Type: Socket drive (internal hex) for easy installation with standard Allen wrenches
• Size: 5/16-18 thread, 5/8 in length

Why It Stands Out

The knurled cup point minimizes loosening in high-vibration environments, while the alloy steel core handles demanding applications. The thermally black oxide finish reduces glare and resists corrosion, making it suitable for machinery, automotive, and general hardware assemblies.

Applications

Ideal for securing pulleys, gears, shafts, and flange assemblies, or any component where a firm, vibration-resistant set screw is required. Suitable for equipment exposed to challenging conditions or frequent disassembly.
