High-Quality Slotted Set Screws

What is a Slotted Set Screw?

A slotted set screw (also frequently referred to as a grub screw) is a specialized, headless fastener designed with a completely fully threaded body. Engineered to be driven entirely into a pre-tapped hole, these unique fasteners are primarily utilized to securely lock an object within or against another object—such as affixing a gear, collar, or pulley firmly to a rotating shaft. Manufactured from premium, industrial-grade materials, they provide a reliable, high-friction hold for critical mechanical assemblies.

Design Features and Mechanical Advantages

Because they are designed without a traditional protruding head, slotted set screws offer several specific mechanical benefits for tight-clearance and internal fastening applications:

• Fully Threaded Body: The threads extend seamlessly across the entire length of the fastener, right to the end of the part, maximizing thread engagement and gripping power within the mating assembly.
• Traditional Slotted Drive: Engineered with a straight, horizontal slot cut directly into the top of the threaded body. This allows the fastener to be easily driven, adjusted, or removed using a standard flat-blade screwdriver, making them highly accessible for routine maintenance.
• Flush Installation: By eliminating a protruding head, the entire screw can sit perfectly flush with or completely recessed beneath the surface of the assembly, ensuring moving parts remain snag-free and functionally safe.
