Square Head 18-8 Stainless Steel Cup Point Set Screws
Fractional Sizes for Corrosion-Resistant Shaft Locking
Square head 18-8 stainless steel fractional size cup point set screws are precision fasteners designed for secure holding power, corrosion resistance, and long-term reliability in demanding environments. These set screws are commonly used to lock components such as gears, collars, pulleys, and bearings onto shafts where dependable torque resistance and precise positioning are required.
18-8 Stainless Steel Construction
Strength with Excellent Corrosion Resistance
Manufactured from 18-8 (304) stainless steel, these set screws offer excellent resistance to rust, oxidation, and many chemicals. This material is ideal for applications exposed to moisture, washdowns, humidity, or mildly corrosive environments. While providing strong mechanical performance, 18-8 stainless steel also maintains a clean, professional appearance, making it suitable for both industrial and visible assemblies.
Cup Point Design
Positive Grip and Vibration Resistance
The cup point tip features a concave cutting edge that bites into the mating surface, creating a strong mechanical lock. This design provides superior resistance to loosening caused by vibration or rotational forces. Cup point set screws are especially effective when securing components to shafts where slip prevention is critical for performance and safety.
Square Head Configuration
Easy Installation and Precise Adjustment
The square head allows installation and removal using standard open-end or adjustable wrenches. This design provides excellent torque control and is ideal for applications requiring frequent adjustments, maintenance, or alignment. Square head set screws are a practical choice in industrial settings where accessibility and reliability matter most.
Fractional Thread Sizes
Compatibility with Standard Shafting
Available in fractional inch thread sizes, these set screws are designed for use with standard U.S. shafting and components. The precise thread geometry ensures smooth engagement, consistent clamping force, and dependable performance across repeated installations.
Common Applications
Trusted Across Multiple Industries
Square head 18-8 stainless steel cup point set screws are widely used in food processing equipment, marine applications, HVAC systems, manufacturing machinery, material handling equipment, and general MRO operations. Their combination of corrosion resistance, secure holding power, and ease of installation makes them a dependable fastening solution for professionals who demand performance and longevity.
