Our industrial iron cast bar knobs are used for tightening, fastening, and pulling on an object . Engineered and manufactured to strict standards, our industrial knobs can be used in every industrial product. Our knobs are available in several styles including: grip knobs, instrument knobs, metal knobs, ball knobs, lobed knobs, plastic soft touch knobs and wing knobs. These knobs are also available in many materials including: plastic, stainless steel, zinc and steel. Many of our handles are available in several color options.
When hand-tightening isn't possible, insert a metal bar between the arms for leverage.
