The bolt knob is designed with a hexagon-shaped star pattern, providing better grip and making it easier to tighten or loosen the knob.
- The surface of the thread is galvanized, resulting in an overall smooth finish with no burrs. The depth of the thread is complete and clear, and the force distribution is uniform.
- This thumb screw can be effortlessly installed and dismantled without tools, and the Thumb Screw offers adjustable tightening control for a secure clamping force.
- Commonly used in applications requiring frequent adjustments, such as printing, instrumentation, industrial equipment, lathes, sawing machines, woodworking machinery, 3D printer beds, mechanical equipment, and grinding machines, this knurled knob screw is a versatile and reliable component.

Threads were good quality and length was perfect. I had to hacksaw the old one into to get it out, replaced the internal nut reassembled the walker. All went perfect. She has her favorite walker back, 1 week after she fell and broke her arm, oops.

I needed two to replace two that broke on my shooting rest. This product works just fine. The only reason I gave it 4 stars is because the black plastic knob is on the small side where as the product picture makes it look larger that what it is.

I got the pack to use for my camera rig and the screws are the correct thread but longer than described. Maybe they sent me the wrong ones? Either way I was able to cut them down and make them work. Just know you may be forced to cut them down.

Was a little tight when first started but after a few turns was a perfect fit to replace on a fog machine

Not super comfortable to operate due to the small size of the knob.
