Northwestern Tools 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.

Reid Supply has a wide range of 4-lobed knobs, from plastic knobs to stainless steel and iron in a variety of thread sizes and mounting types.

Learn more about what solutions exist for your application in our article on selecting the right knobs and handles.

Utilizing shallow lobes, 7-arm prong knobs provide grip with both male and female threaded inserts made from high-durability brass or steel.

Knurling comes in a variety of patterns depending on the application of the knobs you need to help clamp or adjust tools across a variety of workspaces.

Knurled knobs in vertical or diamond patterns increase grip ability, which makes it ideal for scenarios where grip may not be guaranteed due to contact with water or lubricants.

There are many types of knobs that use knurling. Explore all your options for materials and types of knobs by downloading our Guide to Knobs and Handles e-book.

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.
