Titanium Set Screws Manufacturing Process

At Long Hung, our titanium set screws are crafted with precision to meet the demanding standards of industrial applications. The manufacturing process begins with high-purity titanium wire, ensuring corrosion resistance, lightweight performance, and strength. The wire undergoes direct cold forging, a method that shapes the screws without heating, preserving the material’s structural integrity and enhancing its durability.

During forging, the inner shape of the set screw, such as the hex socket, is accurately formed to guarantee a snug fit with wrenches or drivers, preventing slippage and minimizing tool wear. This precision ensures consistent torque transfer and reliable fastening performance, even in high-stress environments.

After forging, screws are threaded using high-precision rolling or cutting techniques, maintaining tight tolerances for both standard and fine threads. Thread quality is essential for axial positioning and part fastening, ensuring smooth assembly and disassembly. The screws then undergo surface finishing and inspection, which further enhances their longevity and resistance to corrosion, oxidation, and wear.

What a Set Screw Is

A set screw is a headless fastener used to secure one part onto another. It stays inside a threaded hole and applies pressure to a shaft or surface to stop movement. Set screws keep components aligned and prevent sliding or rotation in machines, tools, and mechanical assemblies.

This simple structure is why set screws remain one of the most dependable locking fasteners in engineering and industrial applications.

How a Set Screw Works

When a set screw tightens, the tip presses into the mating surface. Friction and contact pressure hold the part in place. The result is stable positioning without the need for external heads or bulky hardware.

Performance depends on:

The point style
The material hardness
The torque applied
The smoothness of the shaft

This direct pressure makes set screws effective for both rotational and axial holding tasks.

Materials Used for Set Screws

Set screws come in alloy steel, stainless steel, brass, nylon, and titanium. Material affects strength, corrosion resistance, weight, and temperature tolerance.
