The DU-BRO Socket Head Cap Screws (Standard) are strong, dependable fasteners designed for a wide variety of RC building needs. Whether you're assembling a new model or replacing older hardware, these screws provide the secure hold and durability your project requires. Each screw is made from high-quality steel and finished with a black oxide coating. This coating helps prevent rust, gives the screws a clean, professional look, and allows them to thread smoothly into place. The socket (Allen) head design makes installation easy and reduces the chance of stripping, even when tightening in tight or awkward spaces.
These screws are commonly used for:
- Mounting engines and motor plates
- Installing servos and electronics
- Securing landing gear blocks
- Attaching control horns and linkages
- General workshop, robotics, and custom mechanical projects
Because socket head cap screws can be tightened firmly without slipping, they're a favorite choice among RC hobbyists who want strong and reliable hardware. Their consistent size and clean threading make them easy to work with on glow, gas, and electric models.
Each package includes 4 screws 4-40 x 1-1/2", making it convenient to keep extras on hand for repairs, upgrades, or new builds. With DU-BRO's reputation for precision and quality, you can trust these cap screws to deliver long-lasting performance in any application.
