Cup Point Socket Set Screws
Cup Point Set Screws for Secure, Adjustable Mechanical Locking
Durable Materials and Construction Options
Cup point set screws are commonly produced from hardened alloy steel, case-hardened carbon steel, or stainless steel to meet a wide range of strength and environmental requirements. Alloy steel set screws provide outstanding tensile strength and wear resistance, making them ideal for high-load and high-vibration environments. Many alloy steel versions feature a thermal baked black oxide finish, which enhances corrosion resistance, improves torque consistency, and provides a clean, professional appearance.
Stainless steel cup point set screws offer superior resistance to rust, oxidation, and moisture exposure. These versions are especially well suited for outdoor, marine, food-processing, and high-humidity environments where corrosion protection is critical.
Cup Point Design for Maximum Holding Power
The defining cup point geometry allows the screw to embed slightly into the shaft or mating surface. This creates excellent resistance to both rotational and axial movement, ensuring components remain securely positioned under load, shock, or vibration. This design is highly effective for maintaining precise alignment in rotating assemblies.
Threading and Installation Benefits
Cup point set screws are available in a full range of fractional UNC and UNF as well as metric thread sizes, providing compatibility with nearly any application. An internal hex drive allows for easy installation and removal using an Allen key, even in confined or recessed spaces.
