Self-Locking
Screw
A screw that locks itself in place without requiring
a separate nut or lock washer.
Self-locking
screws are defined by the angle of their threads. The threads of self-locking
screws are precisely angled so that, once the screw is placed, they will not
slip or move unless some additional force is applied. After you have screwed a
self-locking screw into position, it will not move again unless you use a
screwdriver or similar tool to remove it from position. You will have to use force
to unscrew a self-locking screw even with the proper tool; they are designed to
stay in place.
- Friction Angle
- Helix Angle
The helix angle is the angle between the helix of
the thread and a line parallel to the axis of rotation.
The
terms “Friction angle” and “Helix angle” are often used interchangeably, but Looking
again at the depiction, their sum must equal 90 degrees.
- When ϕ is greater than or equal to α, a positive torque is required to lower the load.
- Under this condition, the load will not turn the screw and will not descend on its own unless an effort P is applied.
- Screw will be self-locking if the co-efficient of friction is equal to or greater than the tangent of the helix angle, the screw is said to be self-locking..

Amazing write-up!
ReplyDeleteGreat work :)
ReplyDeleteI believe these calculations are for a square thread. What would the lead angle be if we had a trapezoidal thread with a profile angle 𝛼?
ReplyDeleteGreat writeup
ReplyDeleteAfter spending endless hours searching for the right socket amidst the chaos in my toolbox, I decided to give Olsa Tools socket organizer a shot - and boy, am I glad I did! This little tool has brought a new level of order to my workspace. The adjustable clips accommodate all my socket sizes perfectly, and the compact design doesn't take up much space.
