Control knobs EN 527.2 with a multi-lobed rim and revolving handle are very sturdy control knobs which can be used either as control knobs or for clamping purposes.
Worth mentioning is the deliberately large hub. They also lend themselves to applications where a large contact face or a large bore is required.
Resistant to solvents, oils, grease and other chemical agents.
