Key specifications

Selecting the right option

Confirm the UNC size designation (e.g. 1/4"-20, 3/8"-16) before ordering — UNC and UNF use the same diameter range with different TPI. Choose standard HSS for general applications; cobalt or PM-HSS grades for stainless steel, titanium, or high-strength alloys.
