These contoured Button Knobs have a generous dome to shank ratio which makes them ideal for both push and pull operations. Threaded Button Knobs have an internal metric thread. The Knock-on type are easily assembled onto a plain shaft/stud by use of a plastic hammer, eliminating threading operations. Once fitted, they are not prone to rotate or loosen with use or vibration.
Material - High-Impact-Resistant Thermoplastic
