Locking Set Screw
Product Overview
Locking Set Screws are critical fastening components used to secure one object within another without protrusion. These screws are commonly employed in mechanical assemblies to prevent relative movement between two parts, particularly where space constraints require internal fastening solutions. Locking set screws feature a headless design and are driven via an internal socket (usually hex or square) or slotted drive. They are widely applied in securing pulleys, gears, collars, and other rotating parts to shafts in a wide array of industries. Engineered to resist loosening under vibration and torque, Locking Set Screws are an essential choice for reliable, secure fastening.
At Flybear Fastener, our commitment to excellence ensures that every Locking Set Screw we produce meets the highest standards for performance and durability.

Material and Manufacturing Process
Locking Set Screws from Flybear Fastener are manufactured using premium materials such as:
- Stainless Steel grades: A2-70, A4-80
- Alloy Steel with thermal hardening
- Carbon Steel (Grade 8.8, 10.9, 12.9)
To ensure performance and durability:
- Raw materials are sourced from certified suppliers.
- Bar cutting and cold forging precede thread rolling.
- Heat treatment is conducted to enhance mechanical strength.
- Surface coatings are applied based on the application: Zinc plating for general corrosion resistance, Black Oxide for low-friction applications, and Hot Dip Galvanization for maximum rust protection.
- Final inspection and automatic sorting devices assure 100% quality control.
Industries and Typical Applications
Locking Set Screws are used across various industries where vibration resistance and secure positioning are essential:
- Automotive Industry: securing bearings, engine components
- Aerospace: fastening in limited access areas
- Machinery and Tooling: fixed pulleys and collars to shafts
- Electronics: grounding terminals and precision assemblies
- Medical Devices: non-invasive fastening
Common search terms include “anti-vibration screw,” “shaft locking screw,” and “socket set screws for pulleys” — proving their critical role in niche applications.
