The DU-BRO Socket Head Bolts With Lock Nuts give RC builders a strong, dependable way to mount important parts on their models. These aircraft-quality fasteners are perfect for areas where strength and reliability are essential—such as engine mounts, landing gear blocks, servo trays, and other structural components.
Each package includes four socket head bolts, four flat washers, and four nylon-insert lock nuts, giving you a complete mounting set in one pack. The socket head design provides excellent grip with an Allen wrench, making the bolts easy to tighten without slipping or stripping. This is especially helpful in tight spaces or when working with harder materials.
The lock nuts include a nylon insert that keeps the hardware from loosening due to vibration—a common issue in RC aircraft, cars, boats, and drones. Paired with the included washers, they help protect wood, composite, and metal mounting surfaces from damage.
You can choose from two versions depending on your model’s size and hardware needs:
-
#178: Uses a 3/32" wrench — Weight: 7 g/pkg
-
#179: Uses a 7/64" wrench — Weight: 13 g/pkg
These bolt sets are great for:
-
Engine mounting
-
Landing gear installation
-
Servo tray mounting
-
Control linkage hardware
-
RC cars, boats, drones, and robotics projects
Made from high-strength aircraft-grade steel, these fasteners are built to last and provide secure, vibration-resistant performance. With DU-BRO’s trusted quality, the Socket Head Bolts With Lock Nuts are a must-have for any RC builder’s workshop or field box.
