Square head set screws are heavy‑duty fastening components designed with a square‑shaped external head for strong wrench or plier engagement. Built for tough mechanical applications, these screws provide secure holding and precise positioning for collars, machinery components, industrial assemblies, and equipment where high torque and strong clamping force are required.
The square head design offers excellent grip and reduces the risk of tool slippage, making these screws ideal for field work, repairs, and environments where fast, reliable tightening is essential. Square head set screws are a traditional style preferred in maintenance, agricultural machinery, industrial equipment, and applications requiring robust, easy‑to‑adjust fasteners.

Square head set screws are commonly used to secure shafts, couplings, rollers, collars, and rotating parts in heavy equipment. Their design allows for quick adjustments using simple hand tools, even in greasy, dirty, or outdoor environments where socket‑drive tools may not be practical.
These screws are available in various points—such as cup, cone, dog, or flat point—allowing them to accommodate different levels of grip, penetration, and holding strength depending on the application. Their rugged design and ease of use make them popular in OEM machinery, repair operations, and industrial settings.
Available in multiple materials, finishes, sizes, and point styles to meet engineering, agricultural, mechanical, and maintenance needs.
