This is a 4pcs set of stainless steel king pin screws intended for the AXIAL Racing SCX10 II front knuckle on RC-scale crawlers. The fasteners are replacement items for the front-knuckle king pin mounting and are supplied as a matched set to keep front-end connections consistent across both sides.
Material: stainless steel, providing basic corrosion resistance appropriate for hobby use on RC crawlers. Do not interpret corrosion resistance as lifetime protection; regular inspection is advised after extended exposure to wet or abrasive conditions.
Dimensions provided from the source: neck diameter 3.97mm, thread diameter 3mm, total length 10.5mm. Confirm these sizes against your existing hardware before installation to ensure correct thread engagement and fit in the front knuckle.
Installation notes: replace the four screws as a set when servicing the front knuckle, start each screw by hand to avoid cross-threading, and tighten until secure without over-torquing to protect knuckle threads. These items are for RC-scale model use only.
