Cast Iron Knobs

Lobed knobs, also called clamping knobs, have a scalloped edge with four grip points to allow for maximum grip and comfort, even while wearing gloves.

These durable lobed knobs are impact- and chemical-resistant and provide a neat appearance for finished applications that require precision adjustments.

Sometimes referred to as fluted knobs, lobed knobs with 10 lobes bridge a valuable gap between lobed knobs and knurled knobs by bringing wider grips than a typical knurled knob, while increasing the number of lobes over much wider gaps in knobs with fewer lobes.

They are ideal in setups where a "soft" grip is desired for hand cranking on equipment or workpieces.
