Description: Knobs have galvanized carbon steel threaded studs to ensure durability, strength, functionality and abrasion resistance. Solid metal threaded studs ensure a secure connection of parts and are suitable for a variety of applications.
The surface knob has a non-slip texture, which makes it easier to tighten and loosen the knob. Threads are neat, the force is even, deep, skidproof, and burr-free.
Safe and secure non-slip thumb screws are perfect for adjusting and tightening control. Premium plastic clamping knobs provide a smooth, beautiful surface and comfortable grip.
Knobs with hand bolts are commonly used in applications where frequent adjustments and tightening are required. Widely used in lathes, drill press, cutting machines, packaging machines, woodworking machinery, printing machines, instruments and industrial equipment, and fixtures etc.
Always tighten the knob tightly to avoid movement of the fixed assembly. Please note that excessive tightening of knobs may damage or peel threads in the joining assembly. Replace knobs as needed.
