The Redcat Racing RER37073 is a set of specialized 2.5x7mm shoulder hex head machine screws. Unlike standard screws, these feature a smooth unthreaded "shoulder" section below the head. This design allows a component—such as a steering knuckle or a suspension arm—to pivot freely around the screw while the threaded portion stays securely fastened to the axle or chassis.
Vehicle Compatibility
These shoulder screws are standard hardware for Redcat’s 1/18 scale LCG crawler platform:
-
Ascent-18 (LCG Rock Crawler)
-
Ascent-18 Brushless
-
Ascent-18 Scout II
Key Features
-
Pivot Functionality: The 2.5mm shoulder acts as a precision bushing, allowing for smooth mechanical movement without the friction of threads rubbing against moving parts.
-
Hex Head Drive: Uses a standard metric hex driver for a secure fit that is much more resistant to stripping than traditional Phillips head screws.
-
Machine Thread: Designed for installation into metal components or pre-threaded plastic inserts, providing a strong and vibration-resistant hold.
-
Essential Maintenance: These screws are often used in high-movement areas like steering kingpins; having a spare set is vital for trail-side repairs.
