5-40 nuts for using a prop-stud
Hey all, Thought I'd throw this out there for anyone wanting to try them.
Running a 5-40 prop screw or "stud" all the way into the crank, is said to strengthen the front crank-housing in the event of a hard impact.
Some of us use long screws and cut them to size... so why not make a "stud" and secure your prop with a nut and washer? or a heavier "brass" nut/washer (tail heavy?)... or a "lock-nut" (no explanation needed...)
McMaster-Carr Co. carries 5-40 size hardware, for a variety of our uses.
STUDS

LOCK-NUTS

HEX NUTS

WASHERS

They also stock 5-40 hex head cap screws, as well as traditional slotted screws, in the lengths we typically need. (check out their selection of 2-56 screws too)
