Fractional Sizes Cone Point 18-8 Stainless Steel Socket Set Screws
18-8 Stainless Steel Cone Point Socket Set Screws in Fractional Sizes
Fractional size cone point socket set screws manufactured from 18-8 stainless steel are precision fasteners engineered for applications that demand strong holding power, corrosion resistance, and long-term reliability. Featuring a sharply tapered cone point, these set screws are designed to penetrate the mating surface, creating a secure mechanical lock that resists both rotational and axial movement.
Cone Point Design for Precise Alignment
The cone point provides a focused contact area that bites firmly into the mating material. This design delivers exceptional holding strength, making these set screws ideal for permanent or semi-permanent installations where precise alignment is critical. They perform especially well when securing shafts, collars, gears, knobs, and rotating components, even in vibration-prone environments. The penetrating tip ensures consistent positioning and minimizes the risk of loosening under load.
18-8 Stainless Steel Material Advantages
Crafted from 18-8 stainless steel (Type 304), these socket set screws offer excellent resistance to corrosion, rust, and oxidation. This non-magnetic alloy is well suited for outdoor, marine, food processing, and chemical-exposed environments where carbon steel fasteners may fail. In addition to corrosion resistance, 18-8 stainless steel maintains reliable strength across a wide temperature range, ensuring dependable performance in demanding conditions.
Internal Hex Drive for Secure Installation
An internal hex (Allen) drive allows for accurate torque application and easy installation using standard hex keys. This drive style enables secure tightening in tight or recessed locations while maintaining a flush, headless profile that does not interfere with surrounding components.
Manufacturing Standards and Size Range
These cone point set screws are produced to ASME B18.3 standards, ensuring dimensional accuracy and consistent performance. Available in fractional UNC and UNF thread sizes, they typically range from #4-40 through 1/2-13, providing flexibility for a wide range of mechanical and industrial applications.
