Set Screws

Set screws (also known as grub screws) are headless threaded fasteners specifically designed to secure the relative position between shafts and rotating components such as hubs, gears, and pulleys. Manufactured from high-hardness alloy steel or stainless steel, they are available with various point types including cup point, cone point, flat point, and dog point to meet different holding force and installation requirements. The cup point design bites into the shaft surface for maximum holding power, the flat point suits frequent adjustment applications, and the cone point is used for precise positioning. Available in metric and inch thread specifications with surface finishes including black oxide, zinc plating, and nickel plating. Widely used in mechanical equipment, transmission devices, mold manufacturing, power tools, and household appliances.
Flat Point Set Screw

Flat Point Set Screw

Flat Point Set Screw (also known as Flat End Grub Screw) is a precision headless fastener engineered for secure positioning and fixation in mechanical, structural, and industrial applications. Crafted from 304 stainless steel, this screw features a hexagonal socket drive (for high-torque installation and anti-slip performance) and a flat end tip (ensuring flush mounting without protrusions, preventing damage to mating parts). Its corrosion-resistant, high-strength properties make it suitable for harsh environments, including food processing, marine use, and automotive manufacturing.
