Cone Point Set Screws

Cone Point Set Screws for Positive, High-Strength Locking

Cone Point Set Screws are precision-engineered fasteners designed to deliver secure, positive locking in mechanical assemblies where alignment, adjustment, and resistance to movement are critical. Featuring a sharply tapered cone-shaped point, these set screws penetrate the mating surface to create a strong, localized grip that resists both rotational and axial motion. Manufactured to ANSI B18.3, ISO 4027, or DIN 914 standards, cone point set screws are widely used in industrial and precision-driven applications.

Durable Materials and Finish Options

Cone point set screws are produced from high-quality materials such as alloy steel, stainless steel, and case-hardened carbon steel to meet varying strength and environmental requirements. Alloy steel versions provide exceptional tensile strength and wear resistance, making them ideal for high-load and vibration-prone environments. These fasteners are often finished with thermal baked black oxide, which enhances corrosion resistance, improves torque consistency, and provides a clean, professional appearance.
Stainless steel cone point set screws offer superior resistance to rust and oxidation, making them well suited for outdoor, marine, and high-humidity environments.

Cone Point Design for Precision Positioning

The defining feature of a cone point set screw is its pointed tip, which embeds into the mating surface and creates a permanent indentation. This ensures repeatable positioning and prevents loosening under vibration, torque, or load fluctuations. The cone point design is especially effective in applications requiring precise alignment and long-term holding power.

Threading and Installation Advantages

Available in both fractional and metric sizes, cone point set screws are offered with UNC, UNF, and metric coarse threads for broad compatibility. An internal hex (socket) drive allows for precise torque application using a hex key, even in confined or recessed spaces.
