Hello!
I could use some advice on selecting a material for a splined shaft. This is a newly designed prototype.
The shaft is small (0.707" OD, 0.375" ID, and about 24" long). It connects an internal combustion engine (prime mover) to a hydraulic pump. At peak design load of the hydraulic...
Hello all.
We are working on a design where a carbon composite panel is fastened to a 4130 steel subframe. The subframe has flat mounting flanges for the carbon panel. The carbon will be attached to the mounting flanges using both an epoxy paste adhesive and Hi-Lok pins. Basically, the...
Hello everyone!
We are having a debate with the mechanical people who actually have to assemble, disassemble and service our designs. They have a strong preference to apply grease or anti-seize to all bolt shanks before assembly, as they think it makes the parts easier to assemble and...
Hi guys.
We have an aluminum part (7050) with several 10-32 tapped Helicoil holes. The Helicoils are the "screw locking" variety.
When we install the fastener, the fit is tight, as you would expect. But the Helicoil seems to strip the cadmium plating off the screw. Is this normal? See...

Resurrecting this old thread, I have a batch of NAS1351-3 (#10-32) socket head cap screws that are drilled for lock wire. The heads strip at a torque value that is below the desired installation torque value. Specifically, they strip at about 65-70 in-lbs (we were attempting to...
How do you decide whether or not a given fastener should get lockwire?
Obviously, through-bolts with a nut don't need lock wire, since the nut is considered reliable enough against loosening (except in the most severe of circumstances).
But for bolts threaded into a blind hole, how do you make...
