They help a bunch...nice to hold an object with both hands while looking at it..
Great pin pointer from Garrett and Metal Detecting Stuff is my #1 source for products. Excellent service
Notes:
These hexes are designed to fit RC4WD wheels. Understand that some wheels internal width may be too wide for the SCX30 axle stub and may not allow a nut to fully seat on the axle to hold the wheel in place.
