Jergens 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.

Industrial-strength bar knobs can be tightened by hand and further secured by inserting a bar between the four prongs for leverage in heavy clamping applications.

These bar knobs are constructed of malleable iron and available in blank, reamed, or tapped styles. They are ideally used in areas where high pressure is needed and a lever or other clamping device doesn’t fit.

We carry bar knobs in 3/4 inch and 7/8 inch sizes. Find out if bar knobs are right for your application by reading about other knob materials and applications in our knowledge center.

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.
