Professor Motor PMTR1146 4-40×1/8″ BRASS Setscrews

Professor Motor #4-40 x1/8-inch BRASS Oval Point Hex Drive Setscrews for Front Axle Height Adjustment

10 setscrews/package

These setscrews are the right size for NSR applications.

These use an Allen wrench that is 0.050 inch (1.27mm) for application.

Brass material and oval point configuration provide the LOWEST FRICTION running against the steel axle and is FAR less likely to gall from lack of lubrication since the brass material is “dissimilar” from the normal steel against steel with more conventional setscrews.
