This set contains four stainless steel king pin screws engineered for the AXIAL Racing SCX10 II front knuckle used on RC-scale crawlers. The components function as direct replacement fasteners for front-knuckle king pin mounting and are supplied as a matched set to maintain consistent geometry and load distribution across both sides.
Material: stainless steel chosen for hobby-grade corrosion resistance and strength. While stainless improves service life versus plated alternatives, routine inspection is advised following extended exposure to water, grit, or corrosive environments.
Dimensions provided from the source: neck diameter 3.97mm, thread diameter 3mm, total length 10.5mm. Verify these dimensions against existing hardware prior to installation to ensure correct thread engagement and clearance within the knuckle assembly.
Assembly notes: replace the four screws together during knuckle service, begin each screw by hand to prevent cross-threading, and torque to a firm but non-destructive setting to preserve knuckle thread integrity. Intended for RC-scale model repair and maintenance only.
