Knurled Knobs

Knurled Texture

The knurled texture on the surface provides better grip, making it easier to tighten or loosen the knob. Safe and secure knurled thumb screws for the ultimate in adjusting and tightening control.

Clear Threads

The threads are neat and clear, the force is even and deep, not easy to slip, and there are no burrs. Screw on type design for easy installation.

Durable Plastic Knob

Durable plastic clamping knobs provide a smooth and beautiful surface as well as a comfortable grip.

Wide Applications

Knurled knobs with hand bolts are commonly used in applications that require frequent adjustments or tightening.

Widely used in lathes, drill presses, sawing machines, packaging and woodworking machinery, printing, instrument and industrial equipment, and fixtures.

Do not over-tighten the knob as this may damage or strip the threads in the mating assembly. Replace the knob if necessary.

I purchased these for one purpose and that is to use them on my Logitech G920 and G923 pedals. They do the job, and not to the item's fault, they only turned two times before the plastic portion made contact with the pedal mount bracket. I would've preferred that I got a minimum of 4 turns, but that is just me.They are of good quality and the knobs are very handy compared to using a hex or torx bit/driver to tighten them.

These work great for mounting the pedals and wheel to a basic metal couch stand. So long as your material thickness isn't thicker than a few mm.

Used these for a home made CNC/Laser tumbler jig. They work just fine.

Product is well made with uniform size & shape of knobs. My application was to connect some modular outdoor furniture sections. They worked well hand tightening. The only issue I had was the head size was close to being too large due to the close spacing of the hole pattern. Not an issue from the Mfr, oversight on my part.
